# 1 Safety

The Vector is inten ded to be used exclusively for recreational purposes in model planes, boats and cars. Using the Vector for other purposes is not supported. Further, using the Vector in situations where its use or failure could result in loss of life, bodily injury or prop erty damage is expressly prohibited.

Eagle Tree Systems, LLC, is not responsible for your use of this product, or for any damages or injuries you may cause or sustain as a result of its usage.



# 1.1 Read the Manual!

This manual contains important instructions related to safety. Read the entire manual before proceeding, to become familiar with the features and operation of the Vector. Failure to correctly configure or operate the Vector could cause damage to personal property or serious injury!

The latest v ersion of this manual is available in the Product Manuals section of the Support tab on http://www.eagletreesystems.com

. If, after you read the manual, you have further questions or problems, see the “How to Get H elp” section below.

Reading this manual is probably more enjoyable, and will probably take less time, than rebuilding your model!



# 1.2 Special Symbols used in the Manual

Warning that could affect safety or result in injury, a crash

, property damage or Vector hardware damage if not heeded

.

Under construction. This feature is experimental, incomplete, or under active development.

Information applicable only for fixed wing models

Information applicable only for multirotor models

Helpful Not e or Tip



# 1.3 General Safety Precautions

In addition to other warnings and other precautions in this manual, the following should always be
observed:

 The Vector is intended for recreational use only, in model aircraft. Any other use is not supported

.

 Never connect ESCs or servos to the Vector until you have verified the airframe type is correctly selected! Doing so can cause multirotor propellers to spin at high speed, or can destroy fixe d wing

servos.

 Always remove propeller(s) or otherwise disable motor(s) when configuring the Vector!

 Always move a safe distance away from the model before starting the motor(s), and never approach the model with the propeller(s) spinning! Never approac h a multirotor when it is armed!

 Always wear eye protection when operating models with propellers!

# USER GUIDE

7  RC models and accessories are not toys! The Vector should not be used by children.

 You should always use a spotter if your eyes are not on your model. For USA customers, please refer
to the Academy of Model Aeronautic s Safety Code at http://www.modelaircraft.org/files/105.PDF and
FPV related code at http://www.modelaircraft.org/files/550.pdf

 Always obey the law when flying. Most video transmitters used for FPV flying requi re an amateur radio license to operate legally.

 If you have never set u p or operated an RC model before, you will need help from an experienced modeler. Local RC clubs are great ways to meet experienced modelers, and receive the required training. T his requirement is especially true for FPV flying, which can be more challenging.

 Never operate your model aircraft near or over buildings, power/telephone lines, or other obstacles. Never operate your model aircraft near or over people or animals ! Nev er operate your model after consuming drugs or alcohol!

 Never operate the Vector in a situation where it may get wet, such as on a rainy day.

 Do not change wiring in your model when any power is applied.

## 2.5.3 Updating your Vector Firmware

Even if you will be configuring the Vector using the stick menus, it’s a good idea to keep your Vector firmware updated, in case we add a feature or resolve an issue that is relevant to your airframe. Our latest software always has the latest Vector firmware included with it.

To check to see if you have the latest firmware, first check
what firmware version is installed on your Vector, which is displayed at the bottom of the Vector boot

- up OSD screen. Or, you can check the version by using the firmware update utility described below. Then, compare your version
number with the latest Vector firmware version we have
relea sed (listed on the software download page on our website).

To update the Vector firmware, install the latest software, connect the Vector to USB, click the “Firmware Update” button in the software (in the bottom row of buttons), and
follow the instructions

.
Make sure that your GPS/Mag is connected to your Vector before updating firmware. The firmware on the GPS/Mag will also be updated automatically, if needed.
Also, note that if you install new software and it detects that the Vector’s firmware needs an update, it will automatically run the firmware update utility.

# 2.7 Glossary of Terms used in the Manual

Here are definitions for some of the terms used throughout the manual.

FPV

– FPV stands for First Person View. If you are not familiar with FPV, there are many websites devoted to it. Our FPV overview web page at http://www.eagletreesystems.com/OSD has a brief tutorial on FPV, which is a good place to start.

OSD

– OSD stands for On Screen Display. The OSD shows flight information, overlaid on the video camera

i mage

.
RTH

– Return to Home. The Vector can optionally return your model to the home point if R/C link is lost.

Software

– the term “ software ” in the manual refers to our Windows PC software application

.
Firmware

– the firmware is the code that runs on th e Vector itself. The latest Vector firmware is included
with the software.

Flight Controller or Stabilizer

– the aspect of the Vector that stabilizes your model during flight

Pitch

– Lift or descent of the nose and tail of the
model (front to back tilt on multirotor s) . Normally controlled by the elevator, or moveme nt of elevons in
same direction

. Roll

– Rocking movement of the wings, side to side (side to side tilt on multirotors) . Normally controlled by ailerons, or movement of elevons in opposite
di rections

.
Yaw

– Turning of the airplane without banking (rotation on multirotors) . No rmally controlled by
the rudder

.
Axis

– an imaginary line drawn horizontally through your model’s wing (for Pitch), horizontally through your fuselage (for roll), or ve rtically through the center of your fuselage (for yaw).

Gain

– a setting that controls how hard the stabilizer works to hold the orientation of the model around a
certain axis

. Oscillations

– rapid swings of your model around one of its axes, due to a gain setting being too high

. Mode 2 Radio : Transmitters with rudder and throttle on the left stick, and aileron and elevator on the right
stick.

Control Stick

– The stick on Mode 2 radios that controls elevator and aileron functions (pitch and roll).

Attitude

– The orientation of the model with respect to the horizon.

2D Mode

– A mode where the model is brought to a level attitude (level flight and level wings) by the Vector
when the control stick is centered.

3D Mode

– A mode where the Vector attempts to hol d the mod el’s present attitude when the control s tick is centered, by moving the model’s control surfaces automatically.

Gyro Mode

– A mode where the stabilizer responds similarly to having gyros installed on the control surface outputs.
Heading

– The pres ent direction of travel of the model with respect to North.

Control Surfaces

– Your model’s elevator, ailerons (or elevons) , flaperons, and /or rudder (if equipped).

# USER GUIDE

12 Mode Switch

– A two or three position switch on your radio transmitter which you have conf igured to control the “Mod” input on the Vector ’s Receiver Connection Harness.

Toggle

– One fairly rapid movement the Mode Switch between its extents. (UP/DOWN or DOWN/UP)

Configuration Gestures

– A series of toggles of the Mode Switch. The number of tim es you toggle the switch determines which configuration step is performed.

PSU

- Power Supply Unit. This refers to the 5V and 12V switching regulators built into the Vector current

sensor.

# 3 Connecting the Vector

This section describes the Vector’s cabling and connections, and how to connect the Vector to your
RC receiver , your servos or ESCs, and your FPV video
transmitter and camera

. 

# 3.1 Vector Controller Connections

The figure below shows the function of each of the Vector’s ports , and other Vector information.



## 3.1.1 Backup Power

If you want the Vector to use a redundant power supply for safety, t he middle pin of the RSSI/5V Backup

connection can be used to supply backup power to the Vector. Normally the Vector is powered by 5V from the Current Sensor/PSU, but the Vector will take power from the backup connection whenever the voltage at this pin is approximately 0.5V higher than the voltage coming from the Current Sensor/PSU.

# USER GUIDE

14 For example, if the backup power is connected to the BEC of your ESC (via your receiver) , and that is supplying 5.0V, the Vector will use the PSU power unless the PSU voltage drops below 4.5V. Likewise, if your BEC is providing 6.0V to the backup power port , the backup power port will always be powering the Vector unless the BEC output fails.

Note that the backup power input will NOT power your camera or video tran smitter. Only the Vector and accessories connected to the “Bus” port will be powered.



# 3.2 Vector GPS/Mag and Current Sensor/PSU Connections

Connections to the Current Sensor/PSU ( Deans TM version shown), the GPS/Mag , and the optional Pitot Airspeed

sensor are shown in the figure below

.

The “Bus” connectors on the GPS/Mag and Airspeed sensors are internally conn ected together . W iring order, or which of the two connectors on each sensor is used

, does not

matter.

In other words, you can plug int o either “Bus” connector, and if you “daisy

- chain” the Airspeed with the GPS/Mag , either unit can be at the head of the chain.

Never connect the GPS/Mag or pitot sensor to the Vector’s AUDIO connection. Doing so will destroy the sensor!

# USER GUIDE

15 

# 3.3 Vector Current Sensor/PSU Power Output

The Vector’s high efficiency and low noise PSU accepts up to 6S voltage input, and provides filtered 5V and up to 12V output at 1A max per channel. It's perfect for powering most FPV gear, and can also power your receiver on multir otors (when NO servos are being powered by the RX!), eliminating the need for an external BEC.

Never use the PSU to power any servos on your model! The PSU can shut off due to excessive power draw, causing a crash! Servos MUST be powered by a stand alon e BEC, a BEC built into your ESC, or a separate radio flight pack!
Note that the 12V regulator does NOT boost the voltage , like a SEPIC. However, the Vector's 12V PSU has a unique Low Voltage Loss feature that drops the regulator’s output by only about 0.5 V if you are using a 3S pack operating below 12.5V. For example, if your 3S pack is at 11.5V, the regulator outputs about 11V. Other

non

- boost switching regulators typically drop the output voltage by 1.3V or more.

SEPIC and other voltage boost regulato rs are generally much less efficient and generate much more UHF band noise, and in many cases you don’t need one. You never need one if your pack is 4s or above, and a ll known cameras and many transmitters will operate well across the 3S pack voltage ran ge. Typically, 1.3GHz
transmitters may provide reduced power output with less than 12V voltage, and 5.8GHz transmitters work fine
at less than 12V. Be sure to check your transmitter manual’s specs to determine this. If your transmitter does
need a boos t when operating at the lower end of 3S, a JST equipped boost regulator can easily be connected into the Vector's video harness (between connections “A” and “E” in the video harness drawing below)

.


# 3.4 Current Sensor Maxim um Continuous Current
, and Load Testin g

The current sensor’s continuous current capability depends on the type of connectors/wires you are using, and
other factors.
If your model draws a large amount of current (greater than approximately 60 amps continuous) m ake sure you verify that your po wer system , including the current sensor, can handle your worst case continuous
current load

.
In high current applications it is recommended (if you can do so safely) that you run your model in an extended stationary “bench” test, similar in duration and p ower usage to your most aggressive modeling, to ensure there are no problems with any connections, wiring doesn’t get too hot, etc. DO NOT OPERATE YOUR MODEL IF
YOU HAVE PROBLEMS DURING THIS EXTENDED STATIONARY TEST!

It is also recommended that the cur rent sensor be mounted so that airflow is directed through one of the openings of the sensor.
Never exceed the manufacturer’s continuous current rating for the types of connectors installed on your current sensor! If the current sensor or wiring becomes too hot during flight due to too much current, the connectors can fail, or the PSU can shut off, causing a crash!

Make sure that the connector contacts on your current sensor and mating connectors are not damaged or weakened. A damaged or weakened con tact can potentially fold over and short when connected, or cause
intermittent in

- flight failures!

# 3.5 Vector Wiring

The Vector’s wire harnesses are shown below. Note that a set of replacement wire harnesses is available ( p/n VEC

CAB

- SET)

. Having additi onal sets make it easier to move your Vector from model to model.

Video Harness

– routes video signals, and provides power from the Current Sensor/PSU to the Vector, and optionally to your video transmitter, camera, and microphone.

Audio Harness

– this cab le connects to your microphone, and also to the audio output of your video transmitter.

Receiver Connection Harness

– this cable connects
between the Vector and your RC receiver/LRS.

GPS Harness

– this cable connects between the Vector and the GPS/Mag

.



## 3.5.1 Vec tor Video Harness + Connecting your Video Camera and Transmitter

The Vector's innovative video harness makes it easy to connect your 5V or 12V cameras and transmitters without keeping an electrician on standby

. The figure below shows a typical hookup, w ith a 12V camera, 12V
transmitter , and a microphone.

# USER GUIDE

17 The first step to wiring your camera and transmitter is to install servo connectors on the wire harnesses that
came with these components , if they don’t have them already . Servo connectors and cri mpers are available online or at your local hobby store. Either FutabaTM or JRTM style connectors will work.

Refer to the figure at right

. Consult the manuals for your camera and video transmitter, identify the signal, power and ground wires, and i ns tall the servo

connectors on these wires.

Alternatively, FPV shops like http://www.readymaderc.com supply Vector compatible servo adapter cables for most cameras
and video transmitters.

Make sure the polarity of th e servo connector is correct, so that the “S, + and

– ” pins of the connector align correctly the “S, + and

– ” pins of the mating female connector on the video harness!

If you are using a camera with a built

- in battery, such as a Go ProTM, the power servo lead does not need to be connected.
Referring to the video harness diagram below , connect the camera’s servo connector to camera connector “F”,
and the video transmitter’s servo connector to transmitter connector “C” on the video har ness. Inside the Vector, the red wire of the camera power connector “D” is internally connected to the red wire of the camera connector “F”, and the red wire of transmitter power connector “E” is internally connected to the red wire of transmitter connecto r “C”. Also, all ground (black) wires are internally connected in the
Vector.



## 3.5.2 Providing power to your Video Transmitter and Camera

Powering your video equipment is typically very easy with the Vector.

# USER GUIDE

18 Here are typical wiring strategies, depending on t he number of batteries desired, transmitter and camera voltages, etc.

Video Setup Wiring Method

Single Battery, 12V camera, 12V transmitter Connect both red PSU power taps “A” to camera and transmitter power inputs “D”
and “E”

Single Battery, 5V

camera, 12V transmitter Connect the white PSU power tap “B” to camera power input “D”. Connect a red PSU power tap “A” to transmitter power input “E”.

Single Battery, 12V camera, 5V transmitter Connect the white PSU power tap “B” to transmitter power input “E”. Connect a red PSU power tap “A” to camera power input “D”.

Single Battery, 5V camera, 5V transmitter Construct or purchase a JST Y cable. Connect the female end of the Y cable to the white PSU power tap “B”, and connect the two male ends of the Y cable to transmitter power input “E” and camera power input “D”.

Separate Video battery(s) Connect video battery(s) of appropriate voltage(s) to camera power input “D” and/or transmitter power input “E”. Note that if you want to use one video battery for both camera and transmitter, a JST Y cable will be needed.

Make sure that you do not make a mistake in the wiring that causes 12V power to be used with a 5V camera or transmitter! This will likely destroy the camera or transmitter.

Remember that if you us e a 3s or lower pack, the 12V power taps will provide a voltage that is about 0.5V less than the present pack voltage. If your video transmitter reduces output power with voltages less than 12V, and you need maximum range, you will need to insert a “boo st” or “SEPIC” regulator between the power tap “A” and the transmitter power input “E” , or use a separate video battery

. Never exceed the 1 amp current limit for ei ther the 5V tap or the 12V taps. The affected voltage regulator may shut off if this is exceeded, which can cause the Vector to turn off during flight if the 5V regulator is affected , as well as shutting off the affected video equipment! Never use the taps for powering equipment other than your video equipment!

Normally, only extremely high power video transmitters would exceed 1 amp, but check your video equipment
manual.

It is ok if you draw up to 1 amp from the 5V regulator and up to 1 amp from the 12V regulator simultaneously.



## 3.5.3 Vector Audio Harness and Audio Connections

If you do not w ant to hear Vector voice alerts or the acoustic variometer , it is not necessary to use the audio harness, so this step can be skipped.

Refer to the figure:

To hear voice alerts or the acoustic variometer from the Vector, connect the audio harness to the Ve ctor’s Audio

connector, and connect your video transmitter’s audio in servo connector (descr ibed above) to the “Tx Audio”

connector on the audio harness

.

To use an external microphone in this configuration, connect the microphone to the audio harness “Mic rophn”

connector , paying attention to the correct pinout

.

# USER GUIDE

19 Note that the voltage supplied to the red wire of the “Camera/Mic” power input connector “D” on the video harness will be supplied to the red wire on the “Microphn” audio harness connector.



## 3.5.4 Vecto r Receiver Harness

The Receiver Harness is used to connect the Vector to the outputs of your receiver. The pin

- out for the
Receiver Harness is shown below.

Do not power your receiver with a voltage higher than 16V.

The Vector does not power your rece iver or servos. You will need to power your receiver and servos as you would in a non

- Vector model, such as with a stand

- alone BEC, a BEC built into your ESC, or a separate battery p ack.
Whatever power is provided to your receiver will be routed through the Vector to your servos. Whatever power is provided by an ESC ’ s BEC will be routed through the Vector to your receiver and servos.
You can alternatively use the 5 volt tap from the PSU (if not being used to power a 5 volt camera or video TX) to

power y our receiver on multirotors. Please see section 3.5.6

, “ Powering your Receiver on Multirotors" f or additional info.
Three types of receiver inputs are supported with the Vector:

Traditional (parallel) : each of the relevant harness connections need s to be connected to the appropriate
output port on the receiver. See section 3.5.7 below for information on connecting the receiver harness inputs to your receiver

.
Serial PPM (SPPM) and S.BUSTM (serial modes) : only the “Ail” connector of the receiver h arness should be connected to the SPPM or S.BUSTM output of your receiver. Your receiver’s outputs are programmed in the Vector, as described later.

Note: Connect only the “Ail” wire to your receiver when using a serial mode. Never connect other wires from the receiver harness to your receiver if you are using a serial mode!

To reduce wiring, if you use a serial mode you can use a needle or small probe to carefully pry up the tabs of the other connections of the receiver harness, remove the unused wires , and save them for later use. Or, just trim off the extra wires.

# USER GUIDE

20 

## 3.5.5 Receiver Connection Harness Load Capacity (Fixed Wing Only)

With typical fixed wing electric model wiring , the ESC’s BEC is conne cted to the Vector’s throttle output channel. This BEC powers the servos, and all servos are connected to the Vector’s servo outputs. If you have this configuration, please skip this section.

Also, skip this section if you do not have large servos, or if the BEC or battery powering your servos is rated at 6

amps continuous o r less (the vast majority are).

If, however, the AIL lead of the Vector’s receiver connection harness takes power from your receiver, and this

powers large servos you have connected to the Vector , OR, you have large servos connected to both your receiver and the Vector, please read the following :

You should not allow more than 6 amps continuous current to flow through the AIL wire.

Note also that the AIL lead of the harness shou ld not be excessively warm after flying, which could indicate that too much current is passing through it.

If your configuration could result in more than 6 amps continuous current flowing through the AIL wire , there are two ways to supply additional power to your servos:

 If you are not using all the servo output connections on your Vector , a male to male servo wire (with the signal line cut!) can be connected between a free servo channel on the Vector , and a free channel on your receiver.

 If all the servo connections on the Vector are being used, a male/male/female Y cable (ET p/n CAB

- Y

- 1 or similar) with the signal line cut can be used to provide additional power to the servos, as shown in Figure 3.



## 3.5.6 Powering your Receiver on Multirotors

Voltage from the 5V tap “B” can normally be used to power your receiver on multirotors , eliminating
the need to have an additional BEC

. One way to do this, assuming the 5V tap is not being used for your camera

or transmitter

, is to connect a female JST to male servo a dapter cable from the 5V tap to a spare receiver
channel. If the 5V tap is already being used, you will need a Y cable to do this.
However, remember that power will go from your receiver to the Vector’s servo outputs, via the red wire of the
“Ail” connec tor on the Vector receiver harness. If your ESCs are not optoisolated from their receiver inputs, this voltage will power the ESCs even if the ESC main power connector is not plugged into the Current Sensor/PSU

. If your ESCs produce startup tones when t he receiver is powered from the Vector, but the ESC main power connector is not plugged into the Current Sensor/PSU, the ESCs are not optoisolated.

# USER GUIDE

21 In this case , it’s important that you make sure you never arm your multirotor when the main ESC power

conne ctor is disconnected from the Current Sensor/PSU. Or, you can address this issue in some other ways:

a) remove/disconnect the red wire from the “Ail” connector, so that power will not pass from your receiver to the ESCs when using the 5V
tap to power your receiver. b) Or, remove/disconnect the power servo wire
from each ESC. This may be required anyway,

as some non

- optoisolated ESCs could be damaged if the red wires are connected together. c) Or, be sure to n ever connect your main pack to the current sensor wi thout having the ESC main power connector also plugged in to the current sensor

.
If one of these steps is not followed , your ESCs will receive power even when the ESC main power connector is not plugged in to the current sensor . This can cause at least tw o potential problems if you
arm the multirotor in this condition:

 The propellers can spin even though the main pack is not connected to the ESCs!

 With some ESCs, a brownout can occur in this condition that has been known to cause these ESCs to

re program th eir endpoints . This can lead to unpredictable results such as propellers spinning at different speeds after arming, possibly creating an unsafe condition!

# USER GUIDE

22 

## 3.5.7 Connecting Receiver and Servos/ESCs to the Vector

First

, connect your ESC or servo wires to the Ve ctor output port s without powering the Vector

, to make sure they reach the desired Vector mounting location . Th en disconnect them before proceeding to the configuration
section.
Never connect ESCs or servos to the Vector servo outputs until you have veri fied the Vector airframe type is correctly selected! If a fixed wing airframe type is selected with a multirotor, the propellers can spin uncontrollably at high speed at power

- up! Likewise, if a multrotor airframe type is selected with fixed wing, the servos can be pushed beyond their endpoints and be destroyed !
The figure below shows the supported airframe types. For each airframe, the arrow indicates t he direction of forward travel, which corresponds to the forward direction of the arrow on the Vec tor label when the Vector is mounted correctly.

If you have dedicated flaps, they d o not connect to the Vector. Connect the flaps directly to your receiver channel t hat is controlled by the desired flap switch.

For the multirotor airframe types, the nu mbers in the figure correspond to the motor numbers on the Vector servo connector label ( 1 = M1, etc.). For quadcopters and hexacopters the curved arrows indicate the correct

motor rotation.

For tricopters, the motor rotation directions are arbitrary

. Also, the yaw servo MUST be digital!

Tricopter rudder control of the yaw servo is initially disabled when the throttle is at its off position. In order to test yaw, you will need to increase the throttle stick slight l y with the system disa r med

.
For He xacopter Y6 and IY6, the blue motors in the figure s below are ON TOP.

## 3.5.8 Connecting you Receiver’s RSSI Output (if available)

Note: If you have a PPM capable receiver that outputs RSSI and/or l ink q uality in the PPM stream, instead of through a separate wire, skip to the next section.

If you wish to display the receiver’s signal strength (RSSI), and your receiver supports this feature, you will need to connect the top (signal) pin of the “ RSSI/5V Backup ” connection of the Vector to your receiver’s RSSI
output. The Vector’s RSSI input is fully buffered wit h a high impedance op amp.
In general, only “LRS” and SpektrumTM receivers support RSSI externally. However, s ome clever people have posted ways of retrieving the RSSI output from traditional receivers on the RC forums.
Make sure you range test your receiver after connecting the R SSI output to the Vector. Some early LRS receivers could lose range when the RSSI output was utilized.

The Vector supports 3 types of RSSI via this connection, depending on your receiver type:

1. Analog RSSI output

- this is the most common RSSI output

2. Pul se Width Modulated (PWM) output

– EZUHFTM and perhaps other receivers use this method.

3. Spektrum FlightlogTM

- The signal pin of the “data” port of your SpektrumTM receiver normally provides FlightlogTM data, which the Vector can display.

Never connect a vo ltage higher than 3.3V to the RSSI input pin! No known receiver outputs an RSSI greater than 3.3V.

For types 1 and 2 above, the minimum and maximum RSSI output of your receiver is learned during the Receiver Analysis Wizard.
If you use an S.BUSTM receiver without an analog RSSI output , a very simple RSSI is provided automatically. The OSD RSSI readout drops to 25% if the receiver indicates packet loss, and goes to 0% if the recevier indicates failsafe.



## 3.5.9 Configuring SPPM Based RSSI and Link Quality

If you have a n SPPM capable receiver that outputs RSSI and/or link quality in the S PPM stream

, and you wish

to view RSSI information

, the RSSI setup steps are as follows:

1) Make sure your receiver is configured for SPPM, and connected to the Vector as described els ewhere in this
manual.

2) Start the software, and run the Receiver Analysis wizard, which should configure the SPPM input to the
Vector.
3) Navigate to the RC Configuration tab, and in the Serial PPM/S

- BUS section, select the PPM channel(s) used for RSSI, and/or Link Quality. You’ll need to consult with your receiver manual to determine these channels. Note that presumably these channels should change greatly when the transmitter is turned on
and off.

4) After you have selected the channel(s) to use, rerun the Rec eiver Analysis Wizard (you can skip the SPPM setup part of the wizard) so that the Vector can learn the minimum and maximum RSSI and link quality outputs.

# 4 Mounting the Vector and Accessories

4.1 Mounting the Vector

4.1.1 Mounting Location and Orientation

Mount the V ector flat and level with the label facing toward the sky and the red arrow on the Vector case facing toward the nose of your model (the direction of forward travel).

The Vector should be mounted as near to the model’s Center of Gravity (CG) as practi cal. Ideally, the Vector
will be mounted with the mark shown in section 3.1 (just behind the red arrow) directly above your model’s CG. However, precise centering may not be critical.



## 4.1.2 Mounting Technique

The Vector should b e firmly and securely mounted to your model, so it won’t come loose or vibrate. The best way to mount it is to use double sided, closed cell (solid, gum like) foam tape. A g reat choice is Scotch/3M
indoor

- outdoor tape, model 411

- DC, but there are many g ood options.

If the Vector is not mounted correctly, or if it comes loose during flight, your model may become
uncontrollable and crash!

It is recommended to do a “test fit” of all your model’s wiring and components before permanently mounting the Vector.
When removing the Vector from mounting tape, twist the Vector rather than trying to pull the Vector up. It’s easier that way 

. Try to mount the Vector and other components so that the USB connection is easily accessible

. If this is not possible, USB extender cables are available at many FPV shops. 

### GOOD AND BAD WAYS TO MOUNT THE VECTOR

# USER GUIDE

27 

# 4.2 Mounting the GPS/MAG Sensor

4.2.1 GPS Signal Interference

RF noise from video transmitters, cameras, and other devices can interfere with GPS reception. It’s important
to mount the GPS/MAG as far away from the se sources as practical

.
Also, obstructions such as trees or buildings that block the Vector from having a clear, unobstructed view of the sky can cause issues with GPS reception.

If the GPS loses signal during GPS flight modes, such as RTH or loiter, the Vect or will exit these flight
modes.

GPS satellites are constantly moving around in the sky, and GPS signals are affected by changes in weather, so GPS fix quality can vary greatly over time, even at the same location.



## 4.2.2 Magnetometer Interference

Power line s generate electromagnetic fields when current flows through them . These magnetic fields will interfere with the compass function of the GPS if insufficient separation is observed . Unless you don’t plan to use the compass ( it ’ s required for multirotor G PS modes and optional for fixed wing GPS modes) you must
mount the GPS/MAG at least 8cm (3.5”) away in all directions from any high current carrying wires, such as your battery wires, ESC w ires, or motor wires . Additionally, magnets (such as motor magne ts or canopy magnets) can interfere with the compass , and the GPS/MAG should be mounted as far away from them as is
feasible

.
If the compass is enabled, and there is electromagnetic interference, GPS flight modes such as RTH and
loiter will not work corre ctly , and the model may fly erratically when in these modes ! Multirotor models could “toilet bowl” and the model may fly the wrong direction in RTH!



## 4.2.3 GPS/MAG Mounting Orientation

The GPS must be mounted so that the top of the GPS (the label) normally f aces toward the sky.

If you are going to use the compass, the GPS/MAG must be mounted flat and level, and facing forward. The GPS/MAG cannot be tilted or rotated relative to the

Vector. The arrow on the GPS/MAG must be pointing in the same direction a s the

Vector arrow.

If the compass is enabled, and the GPS/MAG is not mounted in the correct orientation or detaches from its mounting during flight, flight modes such as RTH and loiter will not work correctly, and the model may fly away at high speed when in these modes! Multirotor models could “toilet bowl” and the model may fly the wrong direction at high speed during RTH!

The GPS/MAG must be flat relative to the Vector. Mounting errors of even a few degrees in the pitch or roll axes can introdu ce noticeable error in the compass heading, leading to toilet bowl behavior in multirotors or inaccurate navigation in planes.
The Vector automatically computes the magnetic declination (compass error) at your location, so it is normally not necessary to r otate the GPS/MAG to correct for compass error.
The GPS/MAG has an LED, which can be viewed from the back of the unit (see the arrow on the label). When the LED is OFF (not blinking) the GPS/MAG has attained a 3D GPS Fix.

# USER GUIDE

28 

## 4.2.4 The GPS Stand and Clip

The GP S Stand is designed for multirotors

, where i t lifts the GPS/MAG sufficiently above the
multirotor frame to avoid electromagnetic interference. However, it can be used for any type of model. The stand must be mounted vertically, and the base can be moun ted either by placing it under 2 or more of the multirotor ’ s arm mounting bolts, or with closed cell, double sided foam tape.

The stand also has a slot that can be used to neatly route the GPS cable.

Make sure that the screw that holds the mounting clip t o the stand is tightened sufficiently to keep the GPS from rotating easily, but don’t tighten it so tightly that the threads are stripped.

If the stand comes loose or rotates during flight and the compass is enabled, GPS flight modes such as
RTH and loi ter will not work correctly, and the model may fly away at high speed when in these modes!

Consider using a small amount of glue or double sided foam tape on the top of the GPS stalk where it meets the clip, to permanently set the direction the GPS/MA G is facing.



# 4.3 Mounting the Current Sensor/PSU

The Current Sensor/PSU can be mounted with double sided foam tape, or with other methods. Before mounting the Current Sensor/PSU, make sure that your ESC/Motor connector, battery connector and video
harness wi ll reach.

It is recommended that the Current Sensor/PSU be mounted so that cooling air can flow into the one of the openings of the current sensor during flight.



# 4.4 Mounting the Optional Pitot Tube

If you have the optional airspeed sensor, the pitot tube shou ld be mounted as follows.

Using two lengths of the included sm all diameter silicon tube, the pressure and static connections of the pitot tube connect to the “+” and “

- ” ports of the MicroSensor, respectively, as shown below.

It is best to mount the pitot tube in your model first, then determine where you will mount the sensor , and then cut the two lengths of silicon tube so they reach between
the two. Note that the sensor itself can be mounted anywhere in the
model.

Follow these guidelines when

mount ing the pitot tube:

1) The pickup end of the pitot tube (the silver colored tip) should be pointing toward the direction of the model’s travel. While best results will be obtained if the pitot tube is perfectly aligned with the direction
of travel in both axes, the “Prandtl” design of the tube will compensate somewhat for higher angles of
attack.

# USER GUIDE

29 2) The static holes on the pitot tube (shown in the figure) should extend at least 1/2” (13mm) past the wing’s leading edge or the nose cone , or past any other obstr uctions

- the farther out, the better. This is to ensure that the static holes and pitot pickup are in undisturbed air.

3) For prop planes, it’s important that the tube be placed so that it is not directly in the plane’s prop

- wash,
which will result in e rroneous readings. The best place to install the tube is on the leading edge of the wing several inches out from the fuselage, as shown in the figure.

4) For jets, gliders, or “pusher” prop planes, the nose cone often provides a perfect mounting location.

After pitot t ube installation, it is recommended that you glue or otherwise attach the silicon hose to the airframe, to reduce the chance that hose vibration or movement which could cause erroneous readings.

Note: the pitot airspeed can be calibrated as de scribed in the “Pitot Airspeed Calibration” section.



# 4.5 Controlling the Vector

The Vector is controlled and optionally configured with the following radio switch inputs:



## 4.5.1 The Mode Switch

The Mode s witch (a 2 or 3 position switch on your radio that is mapped to the “Mod” input of the receiver harness, or mapped to an SPPM or S.BUSTM channel) is the primary way that you communicate with the Vector via your radio.

The mode switch serves two purposes:

1) The position of the switch determines the Vector’s present fli ght mode 2) Toggling the switch (rapid back and forth movement of the switch) invokes the Vector menu system, letting you configure the Vector via your radio sticks, and perform s other operations based on the number of toggles:

 One T o g g l e : switches OSD screen s to the next screen (if multiple screens are configured) , and serves as

an “OK” switch during menus

 Two t o F o u r T oggles: initiates menu mode

 Five t o S i x Toggles: initiates the Vector leveling procedure

.

 Seven t o N i n e Toggles: starts the compass calibration procedure.

 Ten o r m o r e To ggles: reset s G P S home position (when not fl ying)



## 4.5.2 The Submode Switch

The Submode switch is an optional 2 or 3 position switch on your radio, which allows selection of additional flight modes. This switch is useful if you need to utilize more than 3 flight mode s, which is the limit when using just the Mode switch.

The Submode function can be mapped to the “ Aux ” input of the receiver harness, or to an SPPM or S.BUSTM
channel.



## 4.5.3 The Gain Knob

The g ain knob is an optional control that can be used for adjusting stabilizer gains during flight.
The g ain knob can be mapped to the “Aux” input of the receiver harness, o r to an SPPM or S.BUSTM
channel

.

# USER GUIDE

30 

## 4.5.4 The Kill Switch (for Multirotors Only)

The kill switch is an optional control for multirotors that can be used to instantly kill all motors. This can be especially useful for initial flight testing.

A momentary (spri ng loaded) switch can help reduce the likelihood of inadvertent triggering

. The kill switch can be mapped to the “Aux” input of the receiver harness, or to an SPPM or S.BUSTM channel

. Note that the multirotor will rearm instantly when the kill swit ch is disengaged, until about 3 seconds after it’s engaged (in case the kill was accidental). Once 3 seconds have elapsed with the Kill Switch set

, the multi rotor is permanently disarmed until you rearm it.
During RTH (including RTH test modes) the Gain K nob and Kill Switch inputs are disabled, to prevent inadvertant changes in these inputs due to loss of reliable Rx signal.
Make sure that your radio does not trigger the kill switch during fa i lsafe! If it does, the multirotor will shut off, and not re arm until RTH engages (if at all)!



# 5 Configuring the Vector

5.1 Configuration Overview

The Vector can be completely configured using either the onscreen (stick) menus, or the Vector Windows Software (the software). At a high level, c onfiguration consists of thes e steps:

 Configuring your radio to work with the Vector

 Teaching the Vec tor about your radio’s serial channel mapping, if you are using the SPPM or S.BUSTM receiver protocol

 Selecting the airframe type (airframe type must be confirmed with Mode switch after rebooting

– see section 5.6)

 Teaching the Vector about your receiver co nnections , radio stick directions and throws

 Programming the Mode/Submode switches for selecting the desired flight modes

 Configuring the flight controller/ stabilizer

 Configuring Return to Home and other Safety settings

 Configuring the OSD to display wha t you want to see (and hear)

 Configuring and c alibrating the compass , if used

 Configuring the EagleEyesTM FPV Station, if used



# 5.2 Transmitter Channel Mixing

For correct operation, you must make sure that you have disabled channel mixing in your radio, since the Vector does the mixing for you.

For example, if you are using an elevon (fly ing wing) model, your radio must be configured for traditional airframe type rather than elevon type.
Note: if you have selected the traditional fixed wing airframe type, and have secondary control surfaces like dual ailerons or flaperons, you can either h ave the transmitter do the mixing, or have the Vector do simple mixing.

# USER GUIDE

31 

# 5.3 Configuring with the Windows Software

The manual focuses primarily on configuring the Vector using the stick menus, but the concepts are the same
for the software.

Generally, the Vect or can be more quickly and easily configured with the software, especially for first time

users. However, both methods have been made as straightforward as possible.

To configure with the Software, follow these high level steps . These steps primaril y refer to the “Overview”

screen shown below : 1) Read through the rest of the manual to understand the setup steps, warnings, etc.

2) Run the software with the Vector connected to USB. You will also need to have your transmitter bound to your receiver and funct ioning correctly

. 3) Select your airframe by clicking the “Choose Airframe” button.

4) Run the Receiver Analysis Wizard by clicking the “Run Rx Analysis Wizard” button.

5) Make sure that the graphical indicators in the “Receiver Input Monitor and Switch Mapping” section move correctly as you move your radio sticks

, switches , and/or knobs . The sliders representing the control surfaces should move proportionally with your control stick, and in the same direction. If they don’t, something is wrong

– DON’T FLY un til the issue is resolved! 6) Program the desired functions of your mode/submode switch e s using the dropdown menu items in the input monitor section. After completing this step, hit “Apply”, then make sure that as you move your switches, the “Presently Selec ted Flight Mode” displays the correct mode for the switch positions. 7) Assuming you will be using Safety Mode /RTH features, verify that receiver failsafe detection is working correctly by turning off your radio, and making sure that “ In Failsafe Now: Yes! ” appears. Configure Safety
Mode options by clicking the “Configure Safety Mode” button. 8) Configure the controller gains , multirotor settings (if applicable) and other controller settings on the Flight Controller Settings tab , by clicking on that tab, or clicking the “Configure Multirotor Settings” button

.

# USER GUIDE

32 9) With the Vector and the model perfectly level, record flat level mounting by clicking the “Record Flat Level” button. Now, the artificial horizon (AHI) display should show level, and should closely fol low your

movements as you pitch and roll the model. If the AHI is moving sluggishly and not keeping up with your movements, or is rotating on its own, DON’T FLY and contact support. 10) Configure sensors and the compass by clicking the “Configure Compass” bu tton. Note that, if used, the compass must be calibrated at the field, via the described methods. 11) Configure the OSD display by selecting the OSD Setup item in the “tree view” on the left side of the software. 12) Configure data logging and the EagleEyes (if desired) from the “EagleEyes, Data Logging and Flight Map”

tree. 13) If desired, configure manual waypoints from the Waypoints Setup tab.



# 5.4 Configuring the Vector via Stick Menus

This section describes configuring the Vector using the OSD stick menus. This se ction assumes you have already configured your RC transmitter and bound it to your receiver , and connected your receiver and video display to the Vector

, as these steps are required to do stick menu configuration.

You do not need a camera or video transmit ter to configure the Vector with the stick menus. You can directly connect the “composite” input of your video monitor or goggles to the "Vid Tx” output of the Vector Video Harness, and configure without a camera.
All of the steps below can also be complet ed using the software, if desired.



## 5.4.1 Teaching the Vector about SPPM or S.BUSTM Channel Mappings

If you are using SPPM or S.BUSTM, the Vector must fi r st learn how your sticks, switch es and other outputs are mapped to the serial output channels , so that you can control the menus for further confi guration.

The Vector expects the four primary receiver outputs (throttle, aileron, elevator and rudder) to be assigned to serial channels 1 through 4 (in any order). All known radios use channels 1

- 4 for these outputs. If for some reason you have co nfigured your transmitter to use channel 5 or higher for one of these primary outputs, those channels will not be detected by the wizard, and you will need to use the Radio Control Configuration tab of the software to manually configure your serial channel s. If using S.BUS2TM with the FutabaTM RX R7008SB receiver, be sure you select FASTTtestTM 18 channel or 14 channel mode s and link to the receiver from the transmitter’s menu.
Here are the steps to follow to teach the Vector about your serial channel mappin g :

1. Make sure transmitter mixing is disabled, except as described in
the section above.

2. Decide which knobs and switches you want to use for the mode switch, the submode switch, the gain knob, flaps, and/or the kill switch, as desired. Make sure that these knobs and switches are programmed correctly in your transmitter.

3. Turn on your radio transmitter.

4. Apply power to the Current Sensor/PSU, which should power your Vector and receiver.
5. The Vector will automatically detect your receiver mode during startup, and will run the “ Serial Rx Input
Learn Wizard ” (shown at right) if you are using a serial receiver mode

.
If you are using a serial mode, the Wizard will ask you to follow a series of steps. These are detailed below.

# USER GUIDE

33 IMPORTANT: follow these instructions carefully. If you make a mistake, it may be impossible to
continue with stick menu configuration, since the Vector menus cannot be accessed unless the Vector knows the mappings for the Mode switch and the control stick. If you find you cannot invoke the menus after running the wizard, you will need to either rewire your receiver for standard receiver input mode (using the labeled connectors of the receiver harness) and rerun the wizard , or use the software for SPPM/S.BUSTM configuration.

Wizard Prompt Wh at to Do

Click Mode to Learn PPM/SBUS For this step, toggle the switch that you want to be the Mode switch. If the
Vector detects the toggle , the wizard will advance.

Disconnect Motor/Toggle
Mode Make sure your motor(s) or propeller(s) are disabled, and toggle the Mode switch up and down to continue. Note: all Vector outputs are disabled during the wizard.

Throttle Up and Toggle Mode Move your throttle to the full upp throttle position, and toggle Mode.

Throttle Off/Toggle Mode Move your throttle to the off position, and toggle Mode.

Hold Aileron Left/Toggle Mod Hold your aileron stick full left, and while holding, toggle Mode.

Hold Elvtr Back(Climb)/Tog
Md Hold your elevator stick all the way back (for a climb)

, and while holding, toggle Mode.

Hold Rudder Stick Left/Tog Md Hold the rudder stick all the way left, and while holding, toggle Mode.

Flip Submode if Used/Tog
Mode If you are going to use a Submode switch, move that switch to a new position (don’t move it back) and toggle Mode. If y ou are not going to use it, just toggle Mode without moving any switches.

Rotate Gain if Used/Tog Mode Rotate the Gain knob to a new position (make sure that it moves at least
40 % of its maximum turn) and toggle Mode. If you are not going to use it, jus t toggle Mode without moving any knobs

.

Kill switch on if Used/Tog
Md If you wish to use a Kill switch for your multirotor , change its position (hold it in the new position if it’s momentary) and toggle Mode. If you are not going to use it, just toggle M ode without moving any switches.

Flip Flaps Sw if Used/Tog
Md If you wish to use a flap switch or knob with the Vector, change its position and toggle Mode. If you are not going to use it, just toggle Mode without moving any switches.

Learn Done! Clik M d to reboot The Vector has now learned your serial Rx mappings. Click the mode switch to reboot, and continue with the steps below.

If you ever need to change your serial mappings later , just invoke the “ Serial Rx Input Learn Wizard ” menu item in the Ra dio Control Settings menu.



## 5.4.2 Navigating the Stick Menus

Your Vector should now be configured so that you can access the stick menus.

Now t oggle your mode switch twice (two rapid, full movements between the switch’s extents, in less than 2 seconds).

# USER GUIDE

34 This sh ould initiate menu mode, and the Main M enu should appear.

To navigate menus, the elevator stick is used to scroll up and down the
menu list. The aileron stick is used to select or deselect a menu item. When a menu item is selected, the elevator stick is used to increase or decrease the value of the parameter being changed.

Until you run the Receiver Analysis Wizard (described later), you may find that the aileron and/or the elevator directions are backwards when navigating the menus , requiring you to move the sticks opposite to what is shown in the figure.



## 5.4.3 Exiting Menu Mode

There are 4 ways to exit menu mode:

1. Moving the rudder stick . This will immediately exit menu mode, in a ll conditions except when running a wizard.

2. Toggling the Mode switch. Whe n not editing a menu item, this will cause menu mode to be exited immediately.

3. Using left

- aileron to back out of the menu tree (this may not work if you are in a menu wizard)

. 4. Allowing one minute to pass without moving your sticks, unless you are in a wiza rd.

Changes you make to menu settings are NOT finalized until you fully exit menu mode, by one of the methods described above. In other words, if you make a change to a menu item, and then just
disconnect power to the Vector, the setting will not be sav ed!

If you use the rudder or mode switch to immediately exit menu mode, the next time you enter menu mode, you will be taken back to the last used menu for convenience

.


## 5.4.4 Accessing Menus during Flight

For advanced users, the Vector’s menu system can be conf igured so that menus are accessible in

- flight . To do this, invoke menu mode, go to the “ Radio Control Settings ” menu, and set “ Disable Menus When Flying? ” to
“No.”

Note that by default, your control stick is disabled when in menu mode (“ Disable Stick when in Menu? ”) meaning that the control stick will NOT control flight

. The controller is placed in 2D Flight Mode with Hold when menus are invoked, which should keep your model in level flight while navigating menus , assuming level flight is achieved by the controller when not in menu mode.

If you de cide to use in

- flight menus, you must first verify that the Vector has been correctly configured to fly your model straight and
level when in 2D Flight Mode with Hold!



# 5.5 Selecting the Airframe type

The nex t configuration step is to select the Airframe type. Please review the chart in section 3.5.7 to determine the airframe type you should select.

Then, invoke menu mode, select the “ Change Airframe Type... ” menu item
under the “New Model Checklist” menu , an d follow the instructions.

# USER GUIDE

35 Whenever the airframe type is changed, many settings, such as controller gains , receiver settings

, compass calibration, RTH settings, mode switch mappings, and any other airframe specific settings may be changed to their default values for that airframe type. So, remember to change the airframe type first, before making other settings.

Make sure the airframe type is correctly selected! If a fixed wing airframe type is selected with a multirotor, the propellers can spin unco ntrollably at high speed at power

- up! Likewise, if a
multirotor airframe type is selected with fixed wing, the servos can be pushed beyond their endpoints and be destroyed!



# 5.6 Accepting the Airframe Type

For safety, the Vector will ask you to confirm the newly selected airframe type on the next boot

- up after you change it, but only after USB is
disconnected . The Vector’s outputs will not be turned on until you OK the airframe type.

The message at right will appear on the screen dur ing boot for about 30 seconds. T oggle the mode switch to accept the new type, if it’s correct.



# 5.7 Telling the Vector about Transmitter Dual Surface Mixing

If your traditional fixed wing model has dual ailerons /flaperons , elevators, or rudders, and the transmitter does the mixing for these, you need to follow these steps:

 If you are using a standard receiver (not SPPM or S.BUSTM) make sure the “Aux” receiver harness connector is connected to the correct secondary output channel of your receiver (for example, the 2 nd aileron chan nel)

 If you are using a serial receiver mode , you should have enabled this mixing before running the Serial Rx Input Learn Wizard . If you did not, you’ll need to rerun that
wizard.

 Invoke menu mode, and c hange the “Tx Mixed Dual Contrl Surfaces” menu ite m under the “New Airframe Checklist” menu to correspond to the type of second channel you have

.

 Before flying, you will need to connect the servo for the secondary channel to the "Aux1/M5/RPM” Vector output.

If you have two secondary channels, such as two ailerons and two elevators, and you want your transmitter to do the mixing on both channels, you must use a serial receiver mode (SPPM or S.BUSTM) since there is only one Aux input in standard receiver mode. You can select the correct inputs and outputs f or your setup as described in section 5.8 below.



# 5.8 Running the Receiver Analysis Wizard

The Receiver Analysis Wizard (the Wizard ) learns about your
radio stick directions and throws, the minimum and maximum RSSI output of your receiver, your receiver’s fail safe positions, and
other information.

If you make a mistake when you run the wizard, just rerun it later.
Before running the Wizard, make sure that you have hooked up your RSSI (if used), turned off any radio mixing ( except as described earlier ), and set your radio trims as desir ed.

# USER GUIDE

36 Next, invoke menu mode, select the “ Run Receiver Analysis Wizard” menu item under the “ New Airframe
Checklist ” menu, and follow the instructions below:

Wizard Prompt What to Do

DISCONNECT MOTOR/Toggle
Mode Make sure your mo tor(s) or propeller(s) are disabled, and toggle the Mode switch up and down to continue.

During the wizard, the Vector shuts off the Vector throttle output channel for fixed wing, and all the Vector output channels for multirotors.

Turn Transmitter off n ow You have 10 seconds to turn off your transmitter. Make sure your
transmitter is off before the countdown reaches 0!

Turn Tx On and Toggle Mode Turn your transmitter back on, and toggle the mode switch once it has bound to your receiver.

Hold Aile rn Stick Left/Tog Md Hold your aileron stick full left , and while holding, toggle Mode.

Hold Elvtr Back(Climb)/Tog Md Hold your elevator stick all the way back (for a climb) , and while holding, toggle Mode.

Hold Rudder Stick Left/Tog Md Hold the rudder stick all the way left , and while holding, toggle Mode.

Set sticks/throt at cruise/Tg

Control Stick Centered/Tog Md For fixed wing , make sure your control stick (aileron/elevator) is centered, and place the throttle in the position that you think will provide a good cruising speed during RTH, then toggle Mode. Note that you can adjust this cruising speed later in the “Advanced RTH”

menu , even while in flight.

For multirotors, make sure your control stick (aileron/elevator) is centered, and toggle mode

. The throttle position does not matter in this step.

Set throttle at climb/Tog Mod For fixed wing, m ove your throttle to a position that you think will provide a safe climbing throttle. It is better to have your throttle too high here than too low. T h is throttle setting will be used to gain
altitude , compensate for high wind, or attempt to recover from a stall during RTH.

For multirotors, m ove your throttle stick all the way up, and toggle
Mode.

Set throttle off/Toggle Mode Move your throttle sti ck all the way off, and toggle Mode.

Wizard Done

- Tog Mod to reboot The Vector has now learned your receiver settings. Once you click Mode, the Vector will reboot, and the Vector’s servo outputs will be enabled (assuming everything was done correctly).

The Vector will enable its outputs channels after you reboot. MAKE SURE that your airframe type is correct before rebooting!

# USER GUIDE

37 

# 5.9 Configuring Auxiliary Receiver Inputs and Servo Outputs

The Vector lets you configure several different auxiliary inputs (for transmitter mixed second aileron and other secondary control surfaces) and for additional Vector control inputs.

Also, for fixed wing models, the Vector lets you configure up to two auxiliary servo outputs, for secondary

servos.



## 5.9.1 Configuring the Auxilia ry Input C hannel (for non

- serial Rx inputs)

For serial Rx modes (SPP M and S.BUSTM ) , these inputs are mapped automatically wh en the Serial Rx Wizard was run, so this step can be skipped.
With standard receiver mode ( not serial receiver modes) , you can configure the “Aux” input of

the receiver harness to be one of the followi ng:

 Gain knob for adjusting the stabilizer gain in flight

 Submode input for additional flight mode access

Flaps, Second Aileron, Elevator , or Rudder (with transmitter mixing)

.
Motor Kill switch

To configure the input , navigate to the “ New Airframe Check list ”, and select the “ Set Up Aux Inputs/Outputs ” menu item. Then, select the “ Aux Input Function(nonserial) ” menu item and set the input as desired.

Remember to connect the Aux receiver harness input to the correct output on your receiver!



## 5.9.2 Configur ing th e Vector Auxiliary Output Channels (Fixed wing only)

For fixed wing models, the Vector’s two auxiliary outputs can be configured for Second Aileron, Elevator, and/or Second Rudder.

If you don’t have secondary control surfaces, or you selected a mixed se condary channel in the “ Tx Mixed Dual Contrl Surfaces ” menu, you can skip this step.
If your transmitter does the mixing for these auxiliary channels

, the appropriate inputs need to be mapped as
described above . If you want the Vector to do the mixing, do not select an input corresponding to that channel. Instead, just select the correct output as described below.
To configure the outputs, navigate to the “ New Airframe Checklist ”, and select the “ Set Up Aux Inputs/Outputs ” menu item. Then, select the “ Aux 1 Output Channel Functon ” or “Aux 2 Output
Channel Functon ” menu item and set the output as desired.

If you find that you need to have an output channel reversed, do that with the “ Reverse Aux 1 Output? ” or “Reverse Aux 2 Output? ” menu items.

For mult irotors, the auxiliary output channels are set automatically, if needed.

# 5.10 Flight Modes, and C onfiguring the Mode/Submode Switches

5.10.1 Flight Mode Description

The Vector supports a wide variety of flight modes, which you can select in flight using your Mode sw itch, and optionally a Submode switch. The table below describes these modes, and also indicates whether the GPS (with a good 3D fix) and the magnetic compass are required. The fallback flight mode is listed for when either the GPS or Compass is deemed untrustworthy.

Flight Mode Flight

M ode Indicator Description for Multirotors Description for Fixed Wing

2D Mode (No Hold) 2D Control stick sets the amount of pitch or roll. Returns to level flight when control stick is
released. No altitude hold. Sam e

2D Mode with
Hold 2DH Same as 2D Mode, except that altitude hold is
enabled. When in altitude hold mode, the
throttle works as follows:

 Throttle centered: present altitude is held

 Above or below center: multirotor climbs or descends, at a rate determ ined by the position of the throttle. Same as 2D Mode, except that altitude and heading
hold are enabled. Heading
hold uses the ailerons or elevons to hold the present

## 5.10.2 Control Stick Function in Multirotor Modes

The figure below shows the behavior of the multirotor when the control stick is moved , for the prese ntly selected flight mode.



## 5.10.3 2D Hold Flight Mode Information for Fixed Wing

When 2D Hold flight mode is selected for fixed wing, both heading hold and altitude hold will be enabled. Heading hold uses the ailerons or elevons to hold the present hea ding, and altitude hold uses the elevator. The altitude hold's lock is reset every time the e levator stick is moved.

Also, note that if the Vector detects stall

- like conditions (severe roll) , or the model is traveling at a ground speed (based on the GPS) t hat is less than the “Minimum Ground Speed” setting on the Safety Setup tab of the software, both altitude and heading hold will be temporarily disabled.

Since the Vector will use the elevator to attempt to hold the present altitude when the control stick is centered , it’s important that sufficient airspeed be maintained when in 2D Hold mode, to avoid a stall ! Also, caution should be used when attempting to land in 2D Hold mode.

If you want to have altitude hold disabled in 2D Hold mode when your current draw is below a certain level (or permanently if you are flying a sailplane without a motor)

, an altitude hold disable feature is available.

To enable this feature , enter a nonzero amp erage value in the “Disable Altitude Hold when Amps are lower than

___ Amps” setting, on the “Flight Controller Setup” tab of the
software. When set to a nonzero value, and when the Vector detects amp draw below the chosen value, altit ude ho ld is turned off when 2D Hold flight mode is selected during normal flight, and duri ng RTH. Setting this to 0 disables the feature.



## 5.10.4 Programming the Mode Switch

During flight, you can change the Vector flight mode using your mode switch, and optionally a submode switch for additional flight modes. The position of the mode switch
dete rmines the flight mode, and can also be programmed to turn off the OSD screen during flight.

At least one “non

- GPS” flight mode must be configured on the mode or submode switches. Non GPS flight modes, such as 2D and 3D, do not have the “(GPS)”

# 5.11 Configuring the Flight Controller/Stabilizer

The main steps involved in configuring and tuning the flight controller are:

 Setting the controller gains for initial flight

Confirming that the control surfaces are moving in the correct direction

Confirmin g ESC endpoints are correctly programmed

Setting idle throttle, and confirming motor order and rotation direction are correct
Configuring low battery autoland

 S etting flat level mounting , which lets the Vector compensate for small mounting offsets

 Rezeroing the gyros

If you are not familiar with some of the terms used bel ow, please refer to the glossary at the start of the manual, or consider searching for the terms on http:// wikipedia .org

. The concept of controller stabilization gains can be hard to
understand , and many people (including many very experienced pilots) have trouble grasping these concepts

– you are not alone! Fortunately, with the Vector, only a basic knowledge of how

# USER GUIDE

43 gains work is required in most circumstances.

Basic Gains There are four main axes (or directions) th at are controlled by separate gains: pitch, roll, yaw, and altitude hold (vertical). The gains that control these are referred to as “Basic Gains”.

The basic gain s control how strongly the Vector responds to perturbations (stick movements, air turbulen ce, etc.) in each axis.

When you are in a 2D (model leveling) mode, basic gains control
how hard the controller will push your control surfaces (or motors) to return to level flight, when your control stick is
centered

.
If a gain value is too low, the Vector will not push your control surface or motors hard enough to return to level quickly. For example, with a fixed wing plane in 2D Mode , if the roll gain is not high enough, the wings may not return to level quickly (or at all) when you release the st icks.

If a gain value is too high, the Vector may push your control surfaces or motors too hard to return to level,
which can cause oscillations.

If a gain value is excessively high for your airframe, the oscillations can make the model become

unc ontrollable!

When you are in 3D Heading Hold (Direct Rate) mode, the basic gains dictate how strongly the controller will work to keep the model in its current orientation.

Stabilizer Responsiveness The responsiveness control is applicable only in 2D (l eveling) modes. The responsiveness dictates how smoothly the model will follow the user’s stick commands. A higher responsiveness will make your model more stiff and twitchy. A lower responsiveness will make the model feel slower, and more flui d. It is recommended that you change responsiveness only one increment at a time, as a small change can have a significant impact on handling.



### 5.11.1.2 Adjusting Gains The Vector gains are adjusted by invoking menu mode, selecting “Stabilizer Settings” from the main m enu, and changing the gains from that menu.

NEVER use gain settings specified for a different controller with the Vector! Gain values are NOT interchangable between flight controllers!

It is recommended that gains be adjusted up or down in small incre ments (about 10% at a time) until the best setting is found. The chart below shows how too high or too low gains can affect flight:

### 5.11.1.3 Gain Adjustment for Initial Flight

The default gains for the Vector were chosen so that most airframes will fly reasonably well without major adjustments.

However, airframe types vary widely, so the default gains may cause problems with your model. There are
three ways to reduce the likelihood of gain related problems with your first flights:

a) Set up a gain knob as described below , so you can control the gains of one or more axes quickly from your radio, during flight . To do this, you will need to map a knob from your transmitter, as described earlier in the manual

. The Gain Kn ob works differently between fixed wing and multirotor models, as described below

. b) Program your Mode switch so that one or more positions will invoke a flight mode that does not do 2D leveling, in case you need to switch quickly out of leveling mode due to gain or other issues. c) Check an RC forum to see if anyone has posted good Vector gain settings for your particular airframe. Don’t use gain settings for other controllers with the Vector!



### 5.11.1.4 Configuring the Gain Knob for Fixed Wing

For fixed wing, the gain k nob controls overall gain, which scales (multiplies) the pitch, roll, and yaw gains
all at once. The overall gain can be turned to zero (stabilization off) at the lowest knob setting , which effectively lets you use the knob as a stabilizer on/off switch.

For fixed wing, the present value of the gain knob is displayed in the notification area each time you turn the
knob. This readout can be used for setting the “Default/RTH Overall Gain” menu item. Once you find a good overall knob gain setting for your model, you can set this menu item to the value displayed for the knob , which will then be used during RTH, or if the gain knob is otherwise not available

.



### 5.11.1.5 Configuring the Gain Knob for Multirotors

For multirotors, you can select which of the individual ba sic gains (pitch, roll , yaw , and/or altitude) that will be controlled by the knob. To select which axes are controlled by the gain knob, invoke menu mode, select “Stabilizer Settings” from the main menu, and change “ Knob for X Gain control ?” to “Yes” for each gain you want controlled by the knob.

# USER GUIDE

45 For multirotors, the knob will adjust the gains from 50% to 200% of their default values. To see the present settings for these gains, navigate to the Stabilizer Settings menu item, and observe the values di splayed. Values that are mapped to the knob will change in real time on the menu screen.

The basic gain settings(s) are remembered each time you rotate the gain knob. If the gain knob is later disconnected or disabled, the remembered settings are sti ll used.



### 5.11.1.6 Advanced Gains and Settings
Advanced users who fully understand stabilizer concepts can make adjustments in the “Advanced Setup” menu from the
Stabilizer menu.

Don’t change advanced gain settings unless you know what you are doing!

PID Gains: T he Vector employs an “Inner / Outer Loop Flybarless PID Controller” design. Specific loop gains are adjustable in the “Advanced Setup” menu.

PID control theory and PID loop gain adjustments are beyond the scope of this document, and support for making cha nges to the advanced gains cannot be provided.

General information on PID controllers can be found here:

http://en.wikipedia.org/wiki/PID_controller

T he basic gains act as a multiplier on top of the inner loop PID gains. For example, increasing the Pitch/Elevator Basic Gain has the effect of increasing each of the Inner P, I, and D pitch gains by the same proportion.

Pitch and Roll: Th e “Maximum Pitch” and “Maximum Roll” angle settings control the maximum pitch and roll to which your model will be commanded by the controller, when in a 2D mode.

For multirotors, the maximum pitch and roll angles will effectively limit the top speed and the acceleration/deceleration capability of the multirotor, s ince these angles should not be exceeded, even at
full control stick deflection.
Note that the “Maximum Pitch” and “Maximum Roll” settings are not necessarily honored for fixed wing models. At low gain values , the control stick will overcome the Vector’ s stabilization and exceed the specified maximum angles.

3D Direct Rate: When in 3D Heading Hold (direct rate) mode, each 3D Direct Rate setting controls the
rotational rate of the model in the respective axis

, in rotations per second (Hz)

, when t he stick is fully deflected
in the direction controlling that axis . For example, if you wanted your multirotor to attempt a 360 d egree flip
in the roll axis in 0.5 second s ( when the aileron stick is fully deflected ) , set “ 3D Direct Rate Roll Freq ” to 2 Hz

.
If yo u intend to do flips with your multir otor in 3D or center stick flig ht modes, you will likely need to set the pitch and roll direct gains higher than the defaults. 2Hz to 2.5Hz are typical settings for doing flips.

Default Stabilization: The “Default Stab ilization Mode” chooses the flight mode that will be used if the mode switch input is not detected.

# USER GUIDE

46 Correct and Incorrect Control Surface Movement 

## 5.11.2 Verifying Correct Control Surfaces Movement (Fixed Wing)

In addition to making sure that your radio sticks move the control surfaces in the correct directio n, you also must ensure that the Vector’s stabilizer moves the surfaces in the right direction to keep the model in level flight.

To make sure the stabilizer is correctly moving the control surfaces, first select either a 2D or 3D flight mode. If

you are using a gain knob, make sure the gain is turned up enough to have an effect.

Then , pitch , roll and yaw the model as shown in the figure below. As you move the model, the surfaces should move to COUNTERACT (fight) the movement you ’ve made, as shown in the figure. If your surfaces don’t move in the correct direction, something has gone wrong with your setup. Most likely, servo directions will need to be change d in your radio programming. Make sure you rerun the Receiver Analysis Wizard after changing any
servo directions.
Do not fly your model if the control surfaces are not moving in the correct direction. Doing so will
result in loss of control and a crash!



## 5.11.3 Confirming ESC Endpoints are set Correctly (Multirotor only)

For correct mult irotor operation, all of your ESC endpoints must be set the same, so that the idle throttle setting causes each motor to spin at the same speed, and so that the full range of your throttle is utilized by
the ESCs.

Consult the manual for your ESCs to determ ine how to set endpoints, and set them all the same.

Make sure your ESC endpoints are set correctly! If they are not, the motors could spin at different speeds, or at high speed, when armed!

# USER GUIDE

47 

## 5.11.4 Arming and Disarming your Multirotor (Multirotor only)

5.11.4.1 Arm an d Disarm Gestures

The multirotor is armed by moving the throttle stick to the off position and holding the rudder stick in the rightmost position for 2 to 3 second s , until the props spin continuously. For Mode 2 radios, this is done by simply holding the left (rudder/throttle) stick in the lower right

- hand corner (the ARM corner) for approximately 1 second.
Note that as you hold the stick(s) in the arm position, the motors will pulse or “twitch” twice before the props will continuously spin. You must continue holding the stick(s) in the arm position during this sequence , or the multirotor will not arm.

If prefered, the pre

- arming twitches can be disabled by selecting “Allow Fast Arming?” option in the “Advanced Multirotor” stick menu, or under “Other Advanced Settings” on the Flight Controller tab in the software.

The propellers will spin when the multirotor is armed. Do not arm your multirotor with propellers attached until you’ve verified that motor direction, propeller direction, motor o rder, idle throttle and other settings are correct! Make sure you don’t inadvertently move the stick(s) to the arm corner!

The multirotor is disarmed by moving the throttle stick to the off position , and holding the rudder stick in the leftmost position for 1 second. For Mode 2 radios, this is done by holding the left stick in the lower left

- hand corner (the DISARM corner) for approximately 1 second.

The figure below refers to the left stick of Mode 2 radios:

Don’t disarm your multirotor while flyin g unless there’s an emergency ! If you do, the propellers will not spin until you rearm it as described above

.



### 5.11.4.2 Issues that will prevent arming

Here are some conditions that will prevent the multirotor from arming , for safety reasons . An error message wi ll appe ar in the OSD notification area if these conditions are detected (see section 7 on notification messages).

 Arming in a GPS mode (including RTH Test mode) , unless you have set the “ Allow arming in GPS
Mode? ” menu item to “Yes” in the “ Advanced Multir otor ” stick menu. See the table in 6.8.3 if you are uncertain about which modes require a GPS.

 Arming in a leveling mode (2D, 2D with Hold, Cartesian, etc.) if the multirotor is not level. Note that the
multirotor can be armed in 3D mode if it is not lev el!

 Arming if the multirotor is not completely still.

# USER GUIDE

48  T hrottling up if the low battery auto

- land feature has been triggered (the multirotor will arm in this condition).

 Arming if a controller error was detected during Vector boot

- up.

 Arming if the Vector h as not been fully configured.

 Arming if USB is connected.



## 5.11.5 Setting Idle Throttle (Multirotor only)

When the multirotor is armed and the multirotor is level , the motors are commanded to spin at the idle throttle setting. You can change this setting by invo king menu mode , navigating to the “New Airframe Checklist” menu, and changing the “ Idle Throttle (microseconds) ” menu item.

The idle throttle should be adjusted so that the motors spin when armed, but not fast enough to lift the
multirotor. In addition, t he idle throttle should be set high enough so that the propellers will not stall in flight.

If the idle throttle is set too low, the motors won’t spin when armed, and the multirotor could stall during flight. If set too high, the multirotor could tak e off or flip over when armed!

Typically, a good idle throttle value will range from 1150 to 1200 microseconds. However, t his can vary from
ESC to ESC , and may depend on your ESC endpoint settings . Consult your ESC manufacturer for
recommendations.

One way to adjust idle throttle ( without propellers installed!) is to set the value low, arm the multirotor, and observe the motors. If the motors aren’t spinning, increase the idle throttle until they do.

Your Vector has a feature we call “Parachute Mode”, which tries to keep the multirotor level during descent, when you move your throttle all the way down. A good idle throttle adjustment is important for this feature to work correctly.



## 5.11.6 Confirming Correct Motor Order and Direction (Multirotor only)

For co rrect operation, you must ensure that you have connected your ESCs to the correct Vector outputs, and that the ESCs are turning the motors in the correct direction.

Remember that the numbers next to the motors in the airframe diagrams correspond with the

“ M” numbers on the Vector outputs, and that the circular arrows indicate correct prop

rotation.
For tricopters, the motor rotation direction is aribitrary , but don’t forget to match the correct propeller
orienation with the motor rotation direction !

One w ay to test if your setup is correct is to use the motor tester built into the Vector. To do this, invoke menu mode, select the “Multirotor Configuration” menu, and select “Motor
Tester”.

For safety, it is recommended that you r emove propellers before

ru nning the motor tester.

To test a particular motor, select the motor in the menu . I t should briefly spin.
Alternatively, if you select the “ Activate Mode Switch Control! ” item, you can use the Mode switch to control which motor spins. Toggle the m ode switch once for motor 1, twice for motor 2, etc. Deselect the menu item when done.

If t he wrong motor spins, you have made an error in your ESC connections. If the motor spins the wrong
direction , you need to reverse any two of the leads between the ESC and the motor.

The motor tester will be disabled if USB is connected.

# USER GUIDE

49 Also, when you install propellers, make sure that you have selected a propeller of the correct orientation for the direction the motor is spinning.

Make sure you have correctly set up your motor order

, directions and propeller orientations before arming the multirotor with propellers! The multirotor may flip over violently or fly away uncontrollably if these are wrong!



## 5.11.7 Configuring L ow B attery A utoland (Multirotor only)

In add ition to being able to monitor your battery via the OSD, you can also configure your multirotor to descend automatically when the battery is almost depleted , when the Vector is in a flight mode that supports altitude hold

. This option is ON by
default.

When triggered, a message will appear in the notification area, and if you are in an altitude hold enabled flight mode, your throttle setting will be reduced, requiring about 90%
throttle to climb.

If you are in a non

- altitude hold flight mode, the low bat tery alert will appear, but the throttle will not be affected.
To configure this feature , invoke menu mode and bring up the “ Multi rotor Configuration” menu from the main

menu. Here you can turn autoland on and off, as well as setting the cell voltage for l anding.

Since the Vector knows both the present voltage and present current provided by the battery, it is able to approximately determine the “no load” battery voltage even when the battery is under load, so you only need to enter the desired no load per

- cell voltage for landing, rather than trying to estimate the voltage under load. If for some reason you are not using the current sensor, you will need to experiment with the appropiate voltage settings, since the calculation above will be inaccurate. I f the current (amps) readout on the OSD is incorrect, disable low battery autoland!
The Vector automatically calculates the cell count, by default. If you wish to manually enter the cell

co unt, you can do this under the C alibration menu described later

.


## 5.11.8 Setting Flat Level Mounting

Before flying, the Vector needs to correct for any controller mounting offsets that could affect level flight. To do this, place the model so that it is perfectly level (on a level counter or floor) , invoke menu mode, and selec t “Record Flat Level Mounting ” from the “New Airframe Checklist” menu.



## 5.11.9 Rezeroing Gyros

The Vector gyros are factory zeroed, but it never hurts to rezero them occasionally, as this can potentially improve stabilizer performance. The Vector does not nee d to be perfectly level to rezero gyros, but it must remain COMPLETELY STILL during the rezeroing process. To rezero, select the "Rezero Gyros (must be still!) ” menu item under the “Preflight Checklist” menu.

It’s best to rezero the gyros after the mode l has adjusted to the temperature at your flying location.
Never try to rezero gyros with a fixed wing model in the wind, as the wind can buffet the model, which could cause a rezeroing error.

# 5.12 Configuring Return to Home and other Safety Modes

The Retur n to Home feature (RTH) , when configured properly, can return your model to the “home point” if your radio link is lost (in failsafe)

. Additionally, the Vector lets you program the maximum distance and maximum altitude that your model should never excee d.

Here are the steps to configur e Safety Settings :

 Configur ing your Vector and radio so that the Vector can
detect when your radio is in failsafe

 Selecting what you want the model to do when failsafe is detected (land, return home

, return home and land, e tc.)

 Setting the Maximum Distance and Maximum Altitude

 Testing RTH to make sure it’s working correctly (described later in the document)

 Making any necessary adjustments to improve RTH (though normally the default settings work well). See the RTH testing section later in the manual.



## 5.12.1 Configuring Failsafe Detection

You MUST have a receiver that lets you program failsafe positions to use RTH. All modern receivers should support this.

Note: After configuring RTH, make sure you test it as described in the “RTH Ground Testing” section!
The Vector can detect failsafe in one of 3 ways, depending on your receiver’s capabilities. First decide which method you want to use below, and then tell the Vector which method to use by invoking menu mode, navigating to t he “ Safety Configuration Menu ”, and changing the “ Failsafe Detection Method ” item as described below. Then, run the Receiver Analysis Wizard so that the Vector can learn about the failsafe settings.

a) S.BUSTM Method: If you are using S.BUSTM mode with your receiver

, the Vector will detect failsafe automatically. To do this, just select the “ S

- BUS ” option for

“ Failsafe Detection Method ”.

b) Mode Switch Method: If you programmed an “RTH Test” position on y our mode/submode switches, and if your radio supports it, you can program your radio to force the mode/submode switches into the positions that trigger RTH

Test when a failsafe occurs. This is the simplest way to set up failsafe for non S.BUSTM radios.

To do this, program your receiver failsafes as described above, and select the “ Mode Swch ” option for “ Failsafe
Detection Method ”.

c) Throttle Failsafe Method: If you are unable to program a
failsafe on your Mode switch position, or don’t want to use a
mode swi tch position for RTH, an alternative is to program your throttle failsa fe position to be very low

– at least 5%
lower than your normal throttle range. Then, when the Vector sees the throttle in this very low position, it can know

# USER GUIDE

51 that the receiver is in failsafe.

To do this, first select the "Thr Fsafe" option for “ Failsafe Detection Method ” in the menu

.
Then, program your receiver failsafes (following your radio manufacturer’s instructions) with your throttle trim all the way down, as shown in the left part of the illustration.

Next, trim your throttle back up to a higher position. D uring normal operation, you must keep your
throttle trim well above the failsafe setting, as shown in the right part of the illustration.

When you run the Receiver Analysi s wizard, the Vector will detect the low trim failsafe positio n when you turn off your radio. Whenever the throttle is trimmed that low, the Vector will assume the receiver is in failsafe. And, the Vector will learn your normal minimum throttle during t he wizard, when it asks you to set the throttle to the off position.

After you follow these steps, if the error "Throttle Failsafe Incorrect! " is displayed during Vector bootup, that means you did not do the throttle failsafe programming correctly, or the gap between normal and failsafe throttle trim is too small.
NOTE: If you use the throttle failsafe method with multirotors, the multirotor will descend rapidly between the time the throttle is driven low by the failsafe condition, and when RTH is t riggered. This is normally less than 1 second. This delay should not occur or should be reduced if you use the S

BUS or Mode Switch failsafe detection methods.

# USER GUIDE

52 

## 5.12.2 Configuring RTH/Safety Mode

5.12.2.1 Selecting the Desired Safety Mode

The Vector has a few options for what to do when failsafe is
detec te d, referred to as “Safety Modes.” To select the desired failsafe option, invoke the “ Safety Configuration Menu ” and change the “Select the Desired Safety Mode” item.

These options are available:

Land:

For fixed win g, the Vector will try to keep the wings level and shut the throttle off after failsafe is
detected , resulting in a “crash landing” (not a good idea for stall

- prone airframes!)

For multirotors, the multi will descend immediately after failsafe is detected

, at a controlled rate.

Return Home:
For fixed wing, the Vector attempts to bring the model to the home point, and begins circling above
home once there.

For multirotors, the multirotor returns home, and will either hover above the home point at the speci fied altitude, or land, depending on the “Automatically Land at Home” setting.

For fixed wing models, always assume that the propeller may spin when RTH is triggered, even on the ground!

The Vector attempts to detect when the model is on the ground, a nd disables the propeller during RTH if so, but in some conditions, such as with bad GPS readings, altimeter drift, or incorrect settings, the Vector may not be able to detect that the model is on the ground, and the propeller could spin!

Always have your radio turned on before your model is powered, and disconnect your model’s battery before turning off your transmitter. Never engage “RTH Test” via the mode/submode switches unless you are prepared for the propeller to spin!



### 5.12.2.2 Additional Options for RTH
There are several options that can be configured for RTH:

Fly home altitude: t he altitude to ascend or descend to when returning to home , and to maintain once the
model has returned . This is chosen with the “Fly home at this altitude:” setting.

If the altimeter drifts due to changes in barometric pressure or other causes, the fly home altitude will be higher or lower than the actual altitude by the amount of the drift. A very large decrease in barometric pressure , such as can occur if a storm is mov ing in

, might result in the model descending into t he ground when RTH is triggered , if your Fly Home Altitude is set too low !

Ya wing toward home: If you would like the multi rotor to turn (yaw) toward s home before returning
to home , set the “Yaw multi towa rd home for RTH” to “Yes”.

# USER GUIDE

53 This is not reco mmended for line of sight flying, since the multirotor will likely be pointing in a different direction than when you last had control over it, which can be confusing for line of sight.

Advanced Return to Home Options : There are several advanced options that can be configured for RTH, under the “Advanced Setup...” men u. These are described in the Advanced Features section in the document.



## 5.12.3 Configuring Maximum Altitude and Maximum Distance

These settings, found under the “ Safety Configuration Menu

, ” set a virtual boundary that limits how far your model can travel from the home point. This can be helpful to ensure that the model doesn’t fly away unintentionally.

Maximum Altitude: I f this setting is nonzero , the Vector will take over control whenever the model exceeds this limit, and attempt to return the model to the home point.

Maximum Distance Radius: I f this setting is nonzero, the Vector will take over control whenever the distance from the home point ex ceeds this setting , and attempt to return the model to the home point.

The m aximum distance feature will not function if the GPS does not have an adequate signal.
The maximum altitude and distance overrides can be canceled by moving the control stick. If either of the maximum limits continue to be exceeded, the Vector will continue to take over control as soon as the stick is centered. Once the model is back within the set maximum distance and altitude, the control stick can be centered without the Vector taking over control.



# 5.13 The Vector’s LED Indicator

The Vector’s OSD provides detailed information about Vector status, the present flight mode, and any errors that are detected. However, for Line of Sight flying, the LED can be used to determine the Vector’ s status at a glance. Here are the meanings of the Vector LED Indicator blinks:

Blink Pattern Meaning

During boot

- up: Vector is in FIXED WING mode.

If you see this during boot on your multirotor, get away!!!

During boot

- up: Vector is in MULTIROTOR m ode.

If you see this during boot with your fixed wing, disconnect power immediately !

During boot

- up, after airframe indication above: If the LED goes dark for several seconds after the
airframe indication blink above, you need to ok your airframe type with the mode switch . Make sure the type is correct!

An error has been detected. Check the OSD
notification area to determine the cause of the error. See section 9 for error message me anings.

# USER GUIDE

54 

# 5.14 Configuring the OSD

The Vector’s built

- in color OSD has many advanced features and display options. Even so, it can be easily configured to display basic information that is sufficient for most pilots.

The Vector’s OSD will automatically continue to show information on the screen (in grayscale) if your camera should stop functioning in flight. Note: EagleEyes telemetry is NOT available without a functioning camera con nected to the OSD.

Some SkyzoneTM goggles are not compatible with the Vector’s

no

- camera mode. We are investigating this issue. Make sure you test your goggles with no

- camera mode if you think you will need this mode.
All OSD settings are made in the “O SD Setup” menu, from the main

menu.

The steps for configuring the OSD are:

 Adjusting the display so that it is easily readable through your goggles or monitor

 Setting your preferred display units

 Deciding which items you want to display on the OSD

screen

 Setting desired alarms and alerts



## 5.14.1 Adjusting the Display

If yo u are happy with the appearance of the display, no further changes are needed.

If the OSD information is not centered on your screen, change the horizontal and vertical screen shift settings to reposition it. Multirotor is armed, but an error has been
detected. Check the OSD notification area to
determine the cause of the error.

Multirotor is armed.

A 2D Flight Mode is selected

A 3D flight mode (including ‘gyro mode’) is selected

A Loiter flight mode is selected

USB mode is active

# USER GUIDE

55 If the OSD information is too wide for your screen, select Narrow Screen Mode.

If you have trouble reading the text, try changing the black level

, or changing the colors of the text, as described
below.

To change color settings, select the “ Color Setup” menu. You can change the color brightness, intensity, and hue in this menu. Also, you can select which colors to use for text and graphics.

If you prefer a n entirely black and white display, select “white” for the colors of each item, and “black” for the highlight of each.



## 5.14.2 Setting Display Units (English or Metric)

To set the displayed units, navigate to the “English/Metric Units Setup” menu, from the main stick menu.

The Vector lets you set the overall system units, and if desired, differ ent units for individual classes of readouts (speeds, distances, and altitudes ).



## 5.14.3 Choosing what to Display on

the OSD Screen

The Vector’s displayed information is divided into three
classes:

 Numeric readouts

- numeric readouts are displayed
on the first two rows and last two rows of the display. Examples: RSSI, motor battery voltage.

 Graphic s and Indicators

– these are displayed in several different places on the screen. Examples: altitude and airspeed ladders

, compass.

 Notification area

– status and warn ing messages are displayed in this area To configure basic numeric readouts that are typically used , select the “ Numeric Readouts Setup” menu item from the OSD Setup menu. Here’s a description of these readouts:



## 5.14.4 Basic Numeric Readouts

Here is some infor mation on the basic numeric readouts available:



### 5.14.4.1 Electrical Readouts
Pack Voltage, Pack Current, Pack mAH Used: T hese display information about your main flight pack, which must be connected

to the current sensor for these readouts to be valid.

Video Tx Vo ltage : T his is the voltage being supplied to the “Vid Tx” plug “E” on the video harness. This readout would normally be displayed only if you are using a second video battery.

Receiver Voltage: T his is the voltage being supplied via the red wire of the r eceiver connection harness, or via the power pins of the Vector servo outputs.

# USER GUIDE

56 

### 5.14.4.2 Altitude, Speed and Distance Readouts

Barometric Altitude: T his displays the present barometric altitude of the model from the built in pressure

sensor , which is zero reference d (set to zero) when the Vector is powered up.

GPS Altitude: T his displays the present GPS provided altitude, assuming there is a 3D GPS fix. This is also set

to zero at power up

. Both the GPS and barometric altitudes are zeroed when you select the “Reset Home Position” option from the main menu, and for multirotors, each time you arm.

GPS Grounds peed: T his displays the horizontal speed the model is moving over ground, as reported by the GPS. Note that this speed is not the actual airspeed of you r model, if there is any wind.

Pitot Airspeed: I f you have the optional pitot airspeed sensor, this displays the airspeed.

Numeric Climbrate: T his displays the model’s climb or descend rate.

Distance To Pilot: T his displays the horizontal distance betwe en the home point and the model, as reported by
the GPS.

Initially, this readout is in the units selected for distances in the English/Metric Units Setup menu described above. But, when the distance exceeds 1km (for metric system units) the display swit ches to kilometers. Or, if English system units are chosen, if the distance exceeds 1 mile the display switches to miles.

Cumulative Distance: This displays the total distance you have traveled during the flight. This readout is
either in miles or kilome ters, depending on your system units.



### 5.14.4.3 Additional Basic Numeric Readouts

Home Arrow: The home arrow points straight up if you are presently flying toward home . If you are using the magnetic compass, the compass is used to determine the home direction. If you are not using the compass,
the GPS course is used.

If the compasss is not being used, and the model is moving very slowly or not at all relative to the ground, the home arrow will not be accurate , and may display a “?”.

Sensor Temperature: T his readout displays the temperature of the optional loop or micro temperature sensor, described in the Advanced Features section

.
Callsign: T his readout lets you program your amateur radio call sign , to be displayed for 15 seconds every 10
minutes. Th e call sign is programmed using the stick menu: left and right select the position to be changed, and up and down change s the character for that position

.
Flight Time remaining: T his readout shows the approximate flight time remaining, based on your pack mAH setting, and the present amp draw on the battery. This readout is only meaningful if you are flying with a relatively constant amp draw.

Receiver RSSI: T his is the RSSI (Received Signal Strength Indicator) percentage, derived from the Vector’s RSSI input pin described earlier. Note: if the RSSI input was not correctly connected during the Receiver Analysis Wizard, the RSSI indicator will show a “?”.

GPS Position (Lat/Lon): T he “Force Lat/Lon display when?” setting determines when the GPS position w ill be displayed on the screen.

The settings are as follows:

# USER GUIDE

57 Never: GPS position is never displayed
Trouble: GPS position is displayed when radio failsafe is detected, if RTH is triggered , or if an alarm has been triggered

. Low Alt: GPS position is dis played for Trouble, and additionally will display if the present altitude is less than 100 feet/30meters.
Distance: GPS position is displayed for Trouble, Low Alt, and additionally if the distance of the model from
home exceeds the “ RADAR Maximum Radius ” m enu item in the “ Graphics and Indicators Setup ” menu. Always: GPS position is always displayed

You can change the format of the displayed GPS position, depending on your requirements. See the “GPS Configuration” section later in this manual.

GPS Satellit e Count: T his readout shows the number of satellites being used by the GPS

GPS Course: T his shows the present course being returned by the GPS.



### 5.14.4.4 Units display

If “ Display Units for All Items” is set to Yes, the uni ts will be displayed for each readout that has units

.



## 5.14.5 Advanced Numeric Readouts

The Vector has a wealth of parameters that can be configured for display, and

, you can also customize the Vector to display numeric readouts on multiple screens, move the readouts around on the screen, and configure ad vanced features of the read outs, such as displaying “gauge ” and “swatch” readouts

.
These advanced features are configured using the “Advanced
Numeric Readouts...” menu. See the Advanced Features section
later in the document for information on how to do this.



## 5.14.6 Graphics and Indicator Readouts

A variety of graphical and indicator readouts are available with the Vector, which are configured under the “Graphics and

Indicators Setup” menu under the “OSD Setup” menu. Here is a brief description of these:



### 5.14.6.1 S

peed Ladder

T he speed ladder shows the present ground speed of the aircraft, on the left side of the screen.

If the optional pitot airspeed sensor is connected, you can display airspeed (instead of ground speed) on the ladder by changing the “ Use Pitot Spd for RTH/Ladder ” setting.



### 5.14.6.2 Altitude Ladder

T he altitude ladder shows the present barometric altitude of the aircraft, on the right side of the screen.



### 5.14.6.3 RADAR

The RADAR readout is an intuitive feature which makes it easier to keep track of your model’s locatio n relative to home, and the direction your model is travel ing relative to the direction the pilot is facing.

# USER GUIDE

58 There are two modes of RADAR operation :

Home Centered Mode:

The circular indicator in the center of the screen (Home/Center Screen marker) m arks the home point , in a "bird's eye" view map. The RADAR location and direction of travel indicator (the chevron) indicates whe re the model is in relation to home.

As your model moves relative to home, the chevron moves relative to the center of the

scre en. Also, the direction the chevron is pointing indicates the direction the model is traveling, relative to home. So, if your model is flying toward home, the chevron will point toward home, regardless of where it is on the display screen.

Set the “ RA DAR Center Screen is

... ” menu item to “Home” for this mode.

Radar Up Direction: This parameter sets the UP direction of the RADAR feature, when in home centered mode. For example, if you fly your model so that your body is facing 15 degrees N, you would set this to 15. This results in the RADAR icon flying “up” on the Vector screen when you are flying the model in the direction you are facing. Normally, the runway is perpendicular to the direction you are facing.

Model Centered Mode:

In this mode, an airplane icon placed in the center of the screen represents where the model is presently, and an icon representing home is placed on the screen relative to the distance from home, and the direction the model is flying relative to home. To return home , steer so that the home icon is directly above the model on the screen (the model always points up).

Set the “ RADAR Center Screen is... ” menu item to “Model” for this mode.

In both RADAR modes, if you are using the magnetic compass, the compass is used t o determine the direction the model is facing. Otherwise, the GPS course reading is used.

RADAR Maximum Radius: This sets the maximum radius for the RADAR display. Set this to the maximum distance away from home that you typically fly. For example, if you normally fly a maximum of 5000 feet away from home in any direction, set this to 5000. If your model exceeds this distance, the RADAR icon will change from
normal video colors to reverse video colors , to indicate you are out of range.



### 5.14.6.4 Flight Ti mer

The Vector provides a flight timer, which appears in the upper left

- hand corner of the screen, when enabled.

The Flight Timer display is in MM:SS until greater than 59 minutes is reached, then it switches to HH:MM:SS. The flight timer starts count ing up when the model is armed (for multirotors) or when it is flying (for fixed wing). The timer pauses when disarmed or landed.



### 5.14.6.5 Compass The graphical compass indicates the present heading of the model. If the magnetic compass is being used, that
readin g drives the graphical compass. If not, the GPS course drives the compass.

Since movement is required for the GPS course to read accurately, the compass will be inaccurate if your model is not moving relative to the ground, unless you are using the magnet ic compass.

# USER GUIDE

59 

### 5.14.6.6 Motor Batt ery Gauge The motor battery gauge graphically shows the main pack’s remaining mAH. Note that the total mAH must be set correctly for this feature to be accurate.



### 5.14.6.7 Home/Center Screen Marker

Places a small circle with “T” in the center of the screen.



### 5.14.6.8 Flight Mode Indicator
This indicator displays a 2 or 3 digit code for the flight mode presently being used. See the “Flight Mode
Indicator” column in the tabl e in section 5.9 .1 for the code displayed with each flight mode.

Normally the pr esent flight mode is the one being commanded by the positions of the mode/submode switches, but in some conditions, such as loss of GPS signal or receiver failsafe, a different flight mode may be in

use.



### 5.14.6.9 Graphical Variometer
The graphical charting variomet er shows you the present climb or sinks rate, as well as historic rates. You can adjust the graphical variometer as described below:

Graphical Vario Scale (+/

- ): This setting lets you set the maximum climb or sinkrate that will be displayed on
the vario meter. For example, if you set this to 1000, and your altitude units are in feet, the top of the chart will represent 1000 feet per minute (FPM), and the bottom of the chart will represent

- 1000 FPM.

Graphical Var io Update Rate: This setting lets you co ntrol how quickly the points on the chart get updated. If you want a longer history displayed on the screen, you would set the update rate to a lower number, and vice

versa.



### 5.14.6.10 Artificial Horizon Indicator

The Artificial Horizon Indicator (AHI) display grap hically shows you your model’s present orientation with respect to the horizon. There are three display options:

Simple: this option displays a simple, 2 line AHI.

F

- 16 Color: this option shows a full color version of the F

- 16 style AHI. The numbers displ ayed with the AHI indicate the degrees of pitch.

F

- 16 Mono: this displays a black and white version of the F

- 16 style AHI.



## 5.14.7 Setting OSD Alarms

Alarms can let you know about potential flight issues , such as low battery, high altitude, or flying out of range , before they become

serious . When an alarm is triggered for a numeric readout , the numeric readout will flash. Additionally, if you turn the setting on, the OSD will speak the present value of the readout whenever an alarm is triggered (via the audio connection to your video transmitter).

Setting up alarms for common conditions is quite easy with the

Vector. Just navigate to the “Alarms/Alerts Setup” menu from the OSD Setup screen, and select the alarms you

want.

# USER GUIDE

60 To be able to see when an alarm has t riggered, you must have the numeric readout for it displayed, so that you can see it flash.



### 5.14.7.1 Low Pack Voltage Alarm
The alarm for pack voltage is set by specifying the per cell voltage that will trigger the alarm. The Vector automatically detects the cell count for your pack, so you can switch between packs of different cell counts, without needing to reset the alarm each time.



### 5.14.7.2 Low Video Transmitter Voltage Alarm
If you use a separate video battery, you can set the alarm for that (in total volts rather tha n cell volts).



### 5.14.7.3 Low milliamp

- Hours (mAH) Remaining Alarm
When enabled, this alarm will trigger when the remaining mAH in your main pack falls below the specified
percentage. For example, if you want the alarm to trigger when only 20% of your pack’s charge remains, set
this to ‘20’. Note that you must correctly set the total mAH for your pack for this alarm to work.



### 5.14.7.4 High Barometric Altitude Alarm
When enabled, this alarm will trigger when the altitude of your model above the takeoff point exceeds the

spec ified barometric altitude.



### 5.14.7.5 Distance to Pilot Alarm
This alarm will trigger when the horizontal distance between the home point and the model exceeds the specified value. Note that this alarm is always programmed in either feet or meters (not miles or kilo meters)

.



### 5.14.7.6 Speaking Alarm Values
If the option is enabled, when an alarm occurs the OSD will make an alert sound, and read off the name and present value of the readout that is in an alarm condition.



# 5.15 Configuring and Calibrating the Magnetic Compass

5.15.1 Using th e Compass with Fixed Wing Airframes

The magnetic compass built into the GPS/Mag is automatically disabled for fixed wing airframes, and automatically enabled for multirotors.

For fixed wing airframes, using the compass offers these benefits:

 The magnetic c ompass operates even if the model is moving slowly, or not at all. If RTH is triggered downwind, and the wind is so strong that the model is moving very slowly toward home, or even losing ground, the GPS course readout may not be accurate, which could c ause the RTH system to not be able to identify the direction to home without the compass.

 Loiter and RTH circling modes may be more precise

 The compass reading can be used for easy determination of the “RADAR Up Direction” or the EagleEyes
tracker’s “ 0 deg ree pan ” settings

.
However, if you decide to use the compass with fixed wing, it’s very important that the mounting, installation and calibration guidelines for the GPS/Mag are followed, or the compass can make things much worse!

To enable the compass for fixed wing, navigate to the “ Calibration and Sensor Setup ” menu from the main menu, and change “ Enable Compass/Magnetometer ” to “Yes”.

# USER GUIDE

61 

## 5.15.2 Calibrating the Compass

Compass calibration should be done with the model away from electrical fields and metal object s. The best place to calibrate the compass is outdoors , at the field where you will be flying.



### 5.15.2.1 Steps before Calibrating

Before calibrating the compass, make sure that the compass is installed correctly, and that all equipment you plan to fly with,
includ ing cameras, canopies, etc., are fully installed on the model

, and turned on . Adding equipment later can impact the compass
calibration !



### 5.15.2.2 Calibrating using the Stick Menus

To calibrate the compass using the stick menus , follow these steps:

1) Invoke Compass Calibration mode by selec ting the “ Compass Working ok (if used)? ” menu item under the “Preflight Checklist” menu

.
2) When your model is away from metal objects, click the mode switch once to start the pro cess, which will cause the
OSD menu shown above to appe ar. Vector LED should now be solid GREEN

. Then, move your radio away from your

m odel.

3) Slowly tu mble (pitch, roll and yaw) the model in all directions, until the Calibration Progress reaches 100%, and
the Vector LED turns solid RED

. Tumble method doesn’t matter , but make sure model goes inverted during
tumble.

Note: for large fixed wing models
where the above calibration m ethod
is awkward , an alternate tumble method is to pitch and roll the model as much as possible, while slowly spinning (pirouetting) your body.

4) Hold the model horizontally level in front of you, with th e GPS arrow pointing directly toward your body.

5) Slowly spin (pirouette) your body around 360 degrees (full circle) while standing in approximately the same plac e. , until the Calibration Progress reaches 100%, and Vector’s RED LED flashes

. This spin
should take about 10 seconds.

6) The Vector will analyze calibration for 5 to 10 seconds. Rarely, if calibration is inadequate, tumble
calibration mode will start again, and the LED will turn solid GREEN again. Repeat steps 3

- 5 if this

occurs.
7) After calibration completes, verify proper compass operation as described in the “ Testing the Compass”
section below.

# USER GUIDE

62 

### 5.15.2.3 Calibrating using the Mode Switch
For your convenience, you can calibrate the compass without using your video display, as follows:

 Toggle mode switch 7 times

– the Vector’s LED should flash a fast RED/GREEN

 Follow steps 2

- 6 above.

 The LEDs should now return to normal

, indicating that the compass calibration is complete

 After calibration completes, verify proper compass operation as described in the “Testing the Compass”
section below.



## 5.15.3 Testing the Compass

5.15.3.1 Load Testing the C ompass If you are not sure that your compass is mounted far enough away from motor/ESC wiring, or other sources of interference, you can test it by operating your model under load, while it is stationary. First, make sure the compass is displayed, and no te the compass reading. Then, if you can do so safely, run the model at full throttle with propeller(s) attached, but with the model secured so that it cannot move . If the compass reading changes significantly (more than a few degrees), that suggests th e GPS/Mag is mounted too close to electrical wiring or
other sources of interference.



### 5.15.3.2 Field Testing the Compass

It’s a good idea to do a quick check of compass function before each day of flying. Display the compass (either on the Preflight Checklist men u or the main OSD screen) and make sure the compass is pointing in the correct direction.
If you don’t know what direction North is at your field and don’t have a mechanical compass, most mobile phones have apps avail a ble that will let you use your pho ne as a compass. Next, rotate the model slowly 360 degrees (full circle) and make sure the compass smoothly follows your
rotation.



# 5.16 Configuring the EagleEyesTM FPV Station

Please refer to the latest EagleEyes online manual (found on the Support tab on our website) for instructions on configuring the EagleEyes with the Vector.

When coupled with the Vector, the EagleEyes FPV ground statio n provides the following features , which can be configured and controlled directly from the Vector on

- screen menus:

 Receiver Diversity

- when you connect two NTSC or PAL audio/video receivers (of any frequency), the EagleEyes picks the better signal at

an y given time, which can greatly reduce video fades and improve your FPV experience.

 A ntenna Tracking

- t he EagleEyes can control most pan/tilt antenna
trackers , such as the ReadyMadeRCTM tracker . The EagleEyes uses telemetry received from the Vector to point the antenna toward the
model.

 Telemetry

– Telemetry data from the Vector is sent via your video
transmitter to your EagleEy e s, where you can visualize you r flight on your laptop in real time, using the Vector software.

Note: Antenna Tracking and Telemetry are NOT available when the Vector is operating without a camera!

# USER GUIDE

63  Four Channel A/V Distribution

- The EagleEyes has four buffered video/audio output s for connecting multiple sets of goggles and monitors at the same time.

 PowerPanel LCD Display support

– When the optional PowerPanel TM LCD display is connected to the EagleEyes, the model’s present GPS position is automatically displayed via the Vector telemetry . With the LCD, the last k nown GPS position is remembered and displayed, in case you lose contact with your
model.



# 6 First Flight s

Now that you’ve completed the Vector installation and configuration, and verified that the control surfaces

, motor(s), propeller(s), compass, etc., are working correctly, it’s time to prepare for the first flight!

For your initial flights, make sure you fly very conservatively, until you become familiar with the flight characteristics of the Vector on your airframe , and make adjustments as needed

.


# 6.1 Preflight Checklist

The Vector includes an interactive preflight checklist, which lists some of the common things that you should
check (or do) before flying. Of course, no generic list is complete, so this should only serve as a supplement to your normal checklist.

The preflight checklist is invoked from the main menu.

The cumulative time you will spend goi ng through your checklist before flying is probably much less than the time it takes to rebuild your model once.
Note that some of the items on the checklist do not necessarily need to be done each flight (such as setting the pack mAH, rezeroing gyros, set ting flat level mounting , and verifying the GPS/MAG is mounted away from power wires). They are there for your convenience.

Also, s ome of the compass/GPS related items, and the compass display, will not be present on the checklist if you are not using
the magnetic compass.



## 6.1.1 Resetting Home Position

On the preflight checklist, and on the main menu, you’ll find the “Reset Home Position” option. This option lets you finalize the home position for the Return to Home feature. You can also re set the home pos ition by toggling the mode switch 10 or more times. N o t e t h a t t h e h o m e p o s i t i o n c a n n o t b e r e s e t w h i l e f l y i n g

.
Typically, the GPS position accuracy improves over time, and resetting the home position just bef ore takeoff may more accurately set thi s position. Additionally, this feature can be used if you want your home position to
be at a slightly different location from where the GPS was first powered on.

Re setting the home position rezeros the altimeter, the pitot speed sensor (if used), and the GPS altitude readings.
If you are using the Eagle Eyes antenna tracker, make sure the tracker is located close to the home point, for best results.

# 6.2 First Flight Recommendations

6.2.1 Ground Tests before First Flight

6.2.1.1 Vibration Check for Fixed Wing

If you can do so safely, i t is recommended that you p erform a prop

- on engi ne run

- up on the ground with 2D
stabilizat ion enabled (and the gain knob at midpoint or higher , if used) , while watching your control
surfaces for drift. This is especially important to do if you have a nitro, gas, or other high vibration motor.

Don’ t fly your model if your control s urfaces are moving unexpectedly during engine run

- up! You’ll need to find ways of further isolating the Vector, or your airframe, from motor vibration , such as using a
cushioned motor mount.



### 6.2.1.2 Control Direction check for Mu ltirotors

If you can do so safely, after arming the multirotor and verifying that the motors are turning in the correct directions, do the following:

 If you’re in an altitude hold mode, activate the stabilizer by quickly moving the throttle past the halfwa y point and quickly back down.

 If you’re in a non

- altitude hold mode, activate the stabilizer by moving the throttle up slightly, and quickly back down.

 Then, with the throttle in the fully down position

, slowly and slightly move the control stick in the p itch and roll directions, and confirm that the multirotor seems to be responding correctly to the control
stick.

Remember to never arm the multirotor when you or anyone else is close to it, and never approach an
armed multirotor!



## 6.2.2 Flight Mode for Takeoffs

For fixed wing models, it is recommended that you take off either in a non 2D stabilized mode (3D mode, ‘Gyro’ mode, or Stabilization Off mode) , or in 2D mode WITHOUT Hold with your gain knob turned low, until you are sure that your gain and other settings are correct for your model. Once you take off, you can turn the gain up or switch into a 2D stabilized mode, but be prepared to exit that mode if there are problems.
In general, if you take off in 2D WITH Hold mode, note that the model will hold whatev er heading it was last pointing to UNTIL you unlock heading hold by moving the aileron or rudder stick. Make sure that you move one of these sticks after you have the model pointing in the takeoff direction, but before taking off!

For Multirotors, you sh ould always take off in a non

- GPS mode (2D, 2D with Heading Hold, Cartesian, 3D
with Hold , or Center Stick mode ). Once in the air, you can switch to a GPS mode as desired. Also, at least for your first flights it is recommended that a non

- altitude hol d flight mode (2D, 3D with Heading Hold, or Center Stick mode) be available on your mode/submode switches, in case excessive vibration causes issues
with altitude hold.



# 6.3 In

- air Leveling

If you find that your model is not flying or hovering level after you h ave performed the “Record Flat Level Mounting” procedure as described earlier , you can reset level flight while in the air. The procedure is as
follows:

# USER GUIDE

65 

## 6.3.1 Multirotor in

- air leveling

Slight adjustments to multirotor level offset can be corrected as follows: w hile hovering in a non

- GPS 2D flight mode (2D or 2D with Altitude Hold , but NOT Center Stick mode ), and when there is no wind, adjust your aileron and elevator radio trims so that the multirotor is hovering in a stationary position.

Then, land the multir otor, disarm, and toggle the mode switch 5 times. At this point your level trims have been saved. DO NOT undo the changes to your radio trims after doing these steps.

In

- air leveling does not work with Center Stick flight mode.



## 6.3.2 Fixed Wing in

- air levelin g

I f your model is not flying straight and level in 2D Mode WITHOUT H old, first level out the model with your
control stick , then ( while keeping the model level with the stick ) toggle the mode switch 5 times. This
records the level flight orientation fo r your model.

The Vector r emembers your control stick position the moment you first start to move the mode switch. So, you don’t need to worry about keeping the model perfectly level while you toggle the switch 5 times. It only needs to be level at th e start of the toggle sequence.



## 6.3.3 Optimal Fixed Wing leveling

If you want to tune your model for more efficien t flight , it is recommended that you follow these steps:

a) First fly your model with stabilization off (or with overall gain turned off with the gain knob ) and adjust your radio trims for level flight.

b) Land, and rerun the Receiver Analysis Wizard so that the Vector can learn about the new radio trim settings.
c) Perfor m the in

- air leveling procedure in section 6.3.2 above, if needed.



# 6.4 Return to Home Testing and Operation

6.4.1 RTH Limitations

Please be aware of the following RTH limitations:

d) If there are obstacles in the path between the model and home, RTH wi ll not be able to avoid them. You are responsible for your model, even when RTH is engaged! e) If the wind speed is higher than the RTH speed of the model, determined by its settings, the model will NOT return home if flying into the wind. f) RTH will NOT eng age if the GPS sig nal quality is not adequate. “Land” s afety mode will engage instead.

For multirotors

, additionally RTH will only work correctly if your compass is correctly installed and calibrated, as described elsewhere in this document.

For fixed wing, RTH throttle control will not engage if your altitude reading is less than about 60 feet/20 meters, or if your speed is less than 3 MPH or 3K/ H, when RTH is triggered. The throttle will
remain off in these conditions. Also, the RTH throttle will not engage until you have “armed” the throttle by moving the throttle stick up at least once after power

- up.

# USER GUIDE

66 

## 6.4.2 RTH Ground Testing

If RTH is configured correctly, after your GPS as acquired a fix and the home position is set, when you turn your

transm itter off ( ON THE GROUND ) the “RTH Engaged...” message should appear in the OSD notification area of
the video screen

. Additionally, the Flight Mode Indicator on the video screen should change to “RTH”. If you don’t see BOT H the se notifications , RTH will not activate in the event of a receiver failsafe. Please refer back to the RTH configuration section if RTH does not trigger correctly.

For fixed wing models, don’t forget that your propeller may spin at any time when RTH is triggered, even on the ground!



## 6.4.3 In

- air RTH Testing

The simplest way to test RTH in the air is to program a mode/submode switch position to “RTH Test”. When this switch position is selected, RTH should engage, and your model should fly toward the hom e point.

Never intentionally turn off your radio to test RTH in the air. There is a chance that your receiver will not link back up with your radio, w hich could result in a crash!

When in RTH test mode, moving the control stick causes RTH to disengage, a nd the model switches to 2D with Hold flight mode.

Note that for proper operation of RTH T est mode, your trim settings must have been recorded during the Radio
Control Wizard. If you have made significant changes to your trim settings since you ran the W izard, the message “RTH Engag ed: Release Sticks f or Test” may appear when RTH is activated, and RTH will not engage

.
Note: if your multirotor is in Polar or Cartesian flight mode and RTH Test is triggered, remember that it will switch to 2D with Hold fligh t mode during the RTH testing, so the control stick will control the multirotor differently during RTH testing!

If you find that your model returns home correctly, no further adjustments should be necessary. If problems occur, refer to the Troubleshootin g chart later in the document.

Don’t forget to switch out of RTH Test mode before landing!



# 7 Advanced Vector Setup and Calibration

This section covers some of the many Vector settings and features that will appeal to more advanced pilots.



# 7.1 Advanced OSD Set up

The Advanced OSD configuration tools let you configure many
additional readouts with multiple display options , set up multiple screens of readouts, set customized messages to display for alarms,
enable additional voice options, and many more features. See section 10 for a complete list of numeric readouts available.

It is generally faster and more intuitive to do advanced OSD configuration with the software, but full stick menu support is provided.

# USER GUIDE

67 

## 7.1.1 The Advanced Numeric Readouts Menu

Advanced numeric c onfiguration through the stick menus is done by navigating to the "Advanced Numeric
Readouts...." menu from the OSD Setup menu.

If you add advanced readouts to the display screen that are not available on the basic readouts menu, problems can occur if you try to add additional readouts later, using the basic menu. later.
Here is a description of this menu:

Readout Name: When this item is highlighted, moving the aileron stick left and right lets you select the readout you want to modify. Once you have se lected the desired readout, move the elevator stick down to
move to the next menu items. See section 10 for a description of all readouts.

Set Up Gauge/Swatch: This brings up the Gauge and Swatch Setup menu, described below.

Onscreen Label: Option lets yo u change the label displayed to the left of the readout, on the OSD screen. To edit, move the aileron stick right to begin. Then, moving the aileron stick left or right lets you select the position you want to edit, and moving the elevator stick up or do wn lets you select the character to display in that position. Note that some readouts let you optionally display an icon for the readout in the first position.

Display parameter as: This item lets you select the display mode of the readout, as Text, Gau ge, Swatch, or Swatch with Text. See the Gauge and Swatch section below.

Show on Scrns: This item l ets you select which screens (1 through 6 , or a combination thereof ) on whi ch this readout will display.

Display on which Row: The Vector’s numeric re adout display consists of 5 columns (from left to right) and 4 rows (from top to bottom), letting you display a total of 20 numeric readouts on each screen. Rows 1 and 2 are at the top of the OSD display, and rows 3 and 4 are at the bottom of the display. This menu item lets you select
the row where this readout will be located.

Display on which Column: This item lets you select the column on the OSD display where this readout will be
located.

If you select a screen, row and column for a readout that co nflicts with another previously configured readout, an error listing the name of the conflicting readout will display at the bottom of the menu screen, and “Show on Scrns” will be forced to “None”.
If you are setting up many readouts on multiple screens , you can either draw the desired screens ah ead of time on a piece of paper with row/column grids and use that as a setup guide, or use the software for configuration.
Alarm Type for Readout: If you would like to set an alarm for this readout, first decid e whether you want the alarm to be a high alarm (alarm will trigger if the readout’s value is higher than the alarm threshold, such as with distance or altitude), or a low alarm (alarm will trigger if the readout’s value is below the alarm threshold,
such as with voltages). Then, set the item accordingly.

Alarm Trigger Threshold: This item lets you set the point at which the alarm will trigger for the readout (see above).

Alarm Msg: This item lets you program a custom text message that will appear in the notification area when the alarm for this readout (if set) is triggered. See the “ Onscreen label ” item above for instructions on how to use the sticks to edit the message.

Switch to Screen if Alarm?: If you have set up multiple screens of readouts, set ting this item to “Yes” will cause the OSD to switch to the screen containing this readout, when an alarm for it is triggered.

Speak Readout if Alarm?: Setting this item to “Yes” will cause the readout to be spoken via the Vector’s audio output, when the alarm triggers.

# USER GUIDE

68 Periodically Speak Value: Setting this item to “Yes” will cause the readout to be spoken periodically via the Vector’s audio output (interval selected below).

Speech Interval in Seconds: This item chooses the interval between speaking this readout’s value (maximum 107 seconds). If you want this readout to be spoken once a minute, set this item to 60.

Speak Readout's Units? : If you have enabled this readout to be spoken either on alarm, or periodically, setting this item to “Yes” wil l result in the readout’s units (if applicable) to also be spoken. For example “Altitude 2

- 8

- 8

- 6 Feet”.

Display Readout's Units?: If this item is set to “Yes”, the units of the readout (if any ) will be displayed to the right of the readout.



## 7.1.2 Gauges and Sw atches

Most of the numeric readouts can be displayed in gauge and swatch format, as well as numeric format.

Gauge format

– I n this mode, the readout can be displayed in bar graph format, with up to 5 colors indicating the present status of the readout’s va lue.

Swatch format

– I n this mode, the readout is a simple colored square, with programmable color changes, letting you easily see when readout needs your attention. You can also display the numeric value of the readout next to the swatch, if desired.



### 7.1.2.1 Ga uge and Swatch Colors and Thresholds

The reading and color of a gauge (and the color of a swatch) is programmed by selecting the numeric thresholds for which a color change will occur, and selecting the total number of colors to choose from. For example, if you wanted a gauge that reads empty, and is red, when a readout reaches “10” or below, and that reads full, and is green, when the value reaches 20 or higher, you would set the number of colors to be 2, and you would set a threshold where you wanted th e color change to occur (presumably 15, the midway point between the range of the readings).



### 7.1.2.2 Configuring Gauges and Swatches

To configure a readout as a gauge or swatch, first select the readout in the
Advanced Numeric Readouts menu as described above, and select the type of display desired for that readout in the “ Display parameter as ” item. Then, navigate to the “Set Up Gauge/Swatch” menu.



### 7.1.2.3 The Gauge/Swatch Setup Menu
This menu lets you set up the colors and thresholds for a gauge or swatch readout.

Read out Name: This item indicates the readout being changed.

Number of Colors in Gauge: This item lets you select the number of colors that will be used for the gauge or swatch. The range is from 2 to 5. Here are the colors that will display if you selec t 5 colors:

g) Green (indicates the best value of the readout) h) Blue i) Yellow j) Magenta (purple) k) Red (indicates the worst value of the readout)

# USER GUIDE

69 If you select 4 colors, green, blue

, yellow and red are used. If you select 3 colors, green, yellow and red are
used . If you select 2 colors , only green and red are used.

Gauge/Swatch BEST Value: Here, you enter numeric value of the readout that you want to always display the

green color. If a lower number is better for the readout, such as with altitude, you wo uld enter the lowest value here. If a higher number is better, such as with voltages, you would enter the highest number here.

Please see the examples at right. For the “Transmitter Voltage” readout, the best value is set to 12.60 and the worst is 10 .80. The gauge will be green and show full at 12.60V or higher, and will show
empty and be red at 10.80V or lower.

For the “Barometric Altitude” readout, the best value is set to 0

, and
the worst value is set to 400. The gauge will be green and show empty at 0 or lower, and will show full and be red at 400 or higher.

Until you enter the WORST value below, and autofill the thresholds, a warning about the thresholds being incorrect will app ear at the bottom of the menu. This is normal.

Color Thres hold 1, Color Threshold 2, Color Thresh old 3,
Color Threshold 4: The color thresholds let you set the values for the readouts where the color changes will occur. The simplest way to set these up is to set up the best and worst values, and select “Autofil l Thresholds” below. This will divide the thresholds equally between the best and worst values. Or, you can manually change them if you want a different distribution.

Gauge/Swatch WORST Value: Here, you enter numeric value of the readout that you want t o always display
the red color. If a lower number is worse for the readout, such as with voltage, you would enter the lowest value here. If a higher number is worse , such as with altitude, you would enter the highest number here.

Autofill Thresholds !: Select this item to autofill the color thresholds as described above.



### 7.1.2.4 Special note about the Motor Voltage (Pack Voltage) Readout

For the Motor Voltage readout, the values entered for thresholds need to be per - cell voltages (i.e., 4.2) , rather
than over all pack voltages. The Vector automatically detects the cell count for your pack, so you can switch between packs of different cell counts, without needing to reset the pack voltage swatch settings each time.



## 7.1.3 The Advanced Graphics/Indicators Menu

The menu is similar to the basic Graphics/Indicators menu, except that it allows you to select the OSD screens on which the graphics and indicators appear, and you can also enable display of additional battery gauges and waypoints in this menu.



# 7.2 Using Optional RPM and Temperature Sensors

The Vector supports both a n external temperature sensor (micro or loop type) and a brushless RPM

sensor. As of this writing, the existing Eagle Tree temperature and RPM sensors require modifications
to work with the Vector. Eagle Tree plans to release Vector versions of these sensors later.

# USER GUIDE

70 

## 7.2.1 Temperature Sensor

Assuming the Aux2/M6/Temp Vector port is not being used to control a servo or motor output, you can connect a MODIFIED Eagle Tree “Micro Temp Sensor” (P/N TEMP

- MICRO) or “Motor Loop Temp Sensor” (P/N
TEMP

- LOOP) to that port, and display and log temperature.
The simple modification of the sensor involves carefully removing the sensor’s bottom wire from the servo housing, using a probe or needle to gently lift the tab on the housing, and placing that wire in the top position of the housing, as shown below.



## 7.2.2 Brushless RPM Sensor

7.2.2.1 Brushless RPM Sensor Setup

Assuming the Aux1/M5/RPM Vector port is not being used to control a servo or motor output, you can connect
a MODI FIED Ea gle Tree “Brushless RPM Sensor” (P/N RPM

- BRS

- V2 ) to that port, and display and log RPM

. DO NOT connect an Optical or Hall (Magnetic) RPM sensor to the Vector! It could be damaged if you do.

The simple modification of the sensor involves carefull y removing the sensor’s re d and black wires from the servo housing, using a probe or needle to gently lift the tabs on the housing, and reversing the red and black wires, as shown below.

Additionally, the following should be noted about using an RPM s ensor with the Vector:

1) Never power your receiver with greater than 6V when using an RPM sensor . Doing so could damage
the RPM sensor. 2) Dropouts of RPM readings can occur with high RPMs. If you see the RPM sensor reading 0 at higher RPM, an additiona l modification to the RPM sensor is required:

a. Obtain a n MA2C029TAF diode at digikey.com, or

an other distributor.
b. Install it in the black wire of the brushless RPM sensor, as shown. Temp Sensor BEFORE Modification Temp Sensor AFTER Modification

RPM Sensor BEFORE Modification RPM Sensor AFTER Modification

# USER GUIDE

71 

### 7.2.2.2 Brushless RPM Sensor Hookup and Configuration

For correct RPM sensor rea dings, you need to let the Vector know the number of “poles” your brushless motor has. This setting is entered in the “ Num Brushless Motor Poles ” section of the Calibration and Sensor Setup

menu.

Please refer to the Brushless RPM S ensor manual found on t he “manuals” tab of our website for information on how to connect the brushless RPM sensor to your motor, and how to determine the number of poles your
motor has.



# 7.3 Waypoints

The Vector supports up to 26 waypoints

. The Vector displays the Waypoints graphi cally on the OSD screen, making it easy for you to fly to them manually.

At this time, the Vector will not autonomously fly to waypoints.



## 7.3.1 Configuring Waypoints

Waypoints are configured in the software, by selecting the “GPS Waypoints Setup” tab.

Internet c onnection is required to configure waypoints.

On this tab, you can zoom in to the desired area, and add your waypoints by just clicking on the map.

You can also configure the first waypoint (Waypoint A) to be the home position. This lets you set the home point without needing to move the model physically to that point.

Check the “User Waypoint A as Home Position” checkbox to enable this feature.

For th e H ome W aypoint feature to work, the model must get its first GPS position fix within about 500 feet ( 152 meters) of the programmed home waypoint. Otherwise, an error message will appear in the notification area, and the current GPS position will be used instead

.



## 7.3.2 Showing Waypoints on the OSD

To display waypoints on the Vector OSD screen , navigate
to the “ Advanced Graphics/Indicators ” menu from the OSD Setup menu.

On that page, change the “ Waypoints ” item to “Scrn 1” to display the waypoints on the main OSD screen.

Once the GPS gets a good fix, the waypoints will appear graphically on the screen. The way points are color coded, to let you know which waypoint to fly to next (in sequence from Waypoint A to the last waypoint you configured).

l) Next waypoint

– yellow with black outline m) Visited waypoint s

– green with black outline

# USER GUIDE

72 n) Unvisited waypoint s

– purple wit h black outlin e
As you fly over the next waypoint, it changes from yellow to green, and the next waypoint in the sequence turns yellow.
The scaling of the waypoints on the screen is based on the “ RADAR Maximum Radius ” setting in the “Graphics
and Indicato rs Setup ” menu. If a waypoint is farther away than the maximum setting , the colors are inverted ( the next waypoint would be black with yellow outline

, for example)

.



# 7.4 Data Logging

Your Vector has a powerful built in Flight Data Recorder

, which logs a larg e number of flight parameters and notification messages

. Having data from your flight can take the guesswork out of troubleshooting in

- flight

issues , as well as keeping a record of your flights for later enjoyment. The logged data can be downloaded with the
software , and v iewed with our charting utility or with Google Maps

.



## 7.4.1 Configuring Data Logg ing

By default

, data logging is configured to log only when the model is flying (or armed), and the logged dat a will automatically be cleared to make room for new data when the logging buffer fills. These settings increase the likelihood that logged data will be available for analysis if something goes wrong with your flight.

Several additional options are available for choosing when to log data, which data to l og, and how often to log data. These options can be configured under the “ Data Logging Setup ” menu.
If you choose to have data logging stop when the buffer is full, don’t forget to clear the logging buffer before each flight, from the Preflight menu.



## 7.4.2 Down loading, Viewing and Saving Logged Flight Information

With the software, you can download flight information from the Vector, view the data, and save it for later
retrieval.



### 7.4.2.1 Downloading Data
To download and view logged data, connect the Vector to USB, and select the “ EagleEyes and Data Logging” tab

under the ”EagleEyes, Data Logging and Flight Map ” branch in the tree view, and click the “Download from
Vector” button.



### 7.4.2.2 Viewing Data To view logged data on a chart, click the “Display Chart of Logged Data ” butto n.

To view logged GPS Data with Google Maps TM

, navigate to the “Google Flight Map” tab

.

# USER GUIDE

73 

### 7.4.2.3 Viewing Flight Notifications
After downloading data, you can view the notification messages and warnings that appeared on the OSD screen during flight. To do this, click on the “View Flight Notifications” button. See section 9 for the meanings of flight notification messages.



### 7.4.2.4 Sessions
Each time you power on the Vector, a new “Session” is created in the data log. This makes it easy to differentiate data between
dif ferent flights. Sessions are indicated with vertical gray bars on the chart, and individual sessions can be selected on both the chart and the Google Flight Map views.



### 7.4.2.5 Saving and Loading Data Files To save a data log file for later use, click the “ Save Lo gged Data To Disk ” button in the “EagleEyes and Data Logging ” tab of the software.

To load a previously saved file, click the “Load Data File from Disk ” button.



### 7.4.2.6 Using ExcelTM to View Data
The log files are compatible with Excel TM spreadsheet software, and o ther spreadsheet products supporting space
delimited data files

.

To load a saved data file in Excel, click the Open option in Excel, and type “*.FDR” in the file name field

. Then navigate to
the location where you saved the .FDR file, and click on the file

.
Excel should then bring up the “Text Import Wizard”. Choose the “Delimited” option, and on the next page choose “ Space ”

delimiter . The data should then load correctly in Excel.



## 7.4.3 Additional Data Logging and Telemetry Features

# USER GUIDE

74 Several additi onal advanced features for data logging and telemetry are available . These features include:

o) Exporting flight data t o Google EarthTM or Google TracksTM p) P laying back data files with gauges and instruments q) Displaying live telemetry data from the EagleEyesTM FPV
Station , either numerically, via Google EarthTM, or on the
chart.
To access these features, check the “Show Advan ced Telemetry Page” checkbox on the “Eagle Eyes and Data Logging ” tab in the
software. Click on the “File” and “Setup” menu items on the advanced telemetry page for more information.



# 7.5 Advanced RTH Setup

Advanced RTH configuration is done on the “Advanced Sa fety Mode” menu, shown below.



## 7.5.1 Home Altitude Mode

The Home RTH Altitude feature lets you set up two different RTH altitudes, which can be useful if you need a higher RTH altitude for part of the return home. To configure home altitude mode, you set
the a ltitude you want the model to reach when it is close to home (the inner altitude), and choose the distance
from home that will specify when to use
the inner altitude.

To configure dual RTH altitudes, follow these steps:

1) F irst

, select the desired mode by
ch anging the “Home RTH Altitude Mode” on the Advanced Safety Mode menu. The settings available are as
follows:

r) Disable: T he second (inner) RTH altitude settings are ignored. This is the default. s) Normal: W hen your model comes closer than the “Home Altitude Radius” set below

, and RTH is active,
the model will descend or climb to the "Home RTH Altitude" specified below , and return home per your settings.

Throt Off: (fixed wing only) This is the same as “Normal” mode above, except that the t hrottle
is turned off when the model is closer than the “Home Altitude Radius,” which would normally cau se your model to descend to the ground, using the stabilizer to keep the wings level

. This feature is useful if your model returns home, but you still cannot regain RC li nk. Note: if your model easily stalls with the motor off, this may not be a good option for you!

2) Next, set the “ Home RTH Altitude” item to th e desired inner RTH altitude (the altitude that RTH will target when closer than the distance radius below). 3) Set t he “Home Altitude Radius” item to the desired distance from home at wh ich the model will target the
"H ome RTH Al titude" described above

.

# USER GUIDE

75 

## 7.5.2 Other Advanced RTH Settings

7.5.2.1 Minimum Speed for RTH

The “ Minimum Ground Spd (0 disable)” menu item is useful if you are f lying in windy areas, and RTH could be triggered downwind. If your model is returning to home at a speed lower than specified ground speed, RTH will use your 'Climb' throttle setting instead of the 'Cruise' throttle setting to attempt to increase your
R TH speed.



### 7.5.2.2 Enabling Low Altitude RTH (Fixed Wing only)

If you fly in such a way that it’s necessary to have RTH engage the propeller at altitudes below the normal altitude cutoff (such as if you fly off cliffs, or otherwise fly below the altitude of the ta keoff point ) you can set the “ Permit low alt RTH (Caution!)” menu item to “Yes”. Setting this to “Yes” defeats the Vector’s automatic disabling of RTH throttle control below altimeter readings of about 60 feet (20 m).

Since enabling this option incre ases the likelihood that RTH will inadvertently activate your throttle on the ground, it should be used with extreme caution!



### 7.5.2.3 Disabling PCM Glitch Detection
In addition to checking to see if your receiver is in failsafe mode, as an additional layer of pro tection the Vector also monitors the health of the signals coming from your receiver. If the Vector sees receiver pulses that are out of spec (too long or too short), or if servo pulses stop altogether for a channel, RTH will be triggered.

Eagle Tree occasionally gets reports of receivers (usually low cost ones) that will sometimes send invalid signals even when they have a good link . If you see RTH triggering with the message “ RTH Engaged: Too Many
Rx Glitches ” or “ RTH Engaged: Bad Rx Pulsewidths ” a nd you are certain that the receiver is not losing link , and
that there is not a loose connection when these occur, you can set “Disable PCM Glitch Detection” to “Yes”. Please note that if you do this, a broken wire or loose connection from your receiver will NOT trigger RTH!



# 7.6 Acoustic Variometer

The Vector includes a powerful acoustic variometer, with total energy compensation and other advanced
features. The variometer sounds are provided via the Vector’s audio output to your video transmitter.

The var iometer produces a varying tone, which changes as you ascend or descend at different rates. When ascending, the tone will be
broken into pulses , with the tone frequency and the frequency of the pulses increasing as the rate of ascent increases.

When d escending, the tone will be continuous, with the tone frequency decreasing as your rate of descent increases.
Total energy compensation, which helps to eliminate “stick thermals,” is done electronically, using the optional pitot airspeed sensor (preferred ) or the GPS ground speed if the pitot is not used.

The variometer is configured via the “ Audio/Variometer Setup ” menu, described below.

Mute Variometer: To enable the Variometer output, set this to “No.”

Set Variometer Volume: Sets the volume of the acou stic variometer. Note that the purpose of the volume control is to match the volume of the variometer with the volume of the flying sounds (if you use a microphone), and the voice alerts.

# USER GUIDE

76 Vario Averager Seconds : This setting controls the averaging per iod of the variometer, in 10ths of a second units. For faster response, lower periods are recommended, but in rougher air longer periods may be required
to avoid false alarms.

Vario Minimum Sinkrate (Deadband) : T his setting controls the minimum sinkrat e. Normally, this would be set to the standard sinkrate of your model , i.e., the rate at which it descends in smooth air with no thermals. When you descend at a rate greater than this sinkrate, the variometer will start to sound

Vario Minimum Climbrat e (Deadband) : T his setting controls the minimum climbrate. When you ascend at a rate greater than this climbrate, the variometer will start to sound,

Set Vario Audible Tone Gain: This setting changes the amount the variometer pitch cha nges as the climb rate
increases or decreases. If you are not hearing enough change, increase this parameter, and vice versa for too much frequency change.

Total Energy Comp Perc e nt: T his adjusts the scaling of the Total Energy Compensation calculation. 100%
means that Kinetic Energy is converted into Potential Energy directly, i.e., any change in airspeed is assumed to directly negate any change in altitude. Less than 100% reduces the degree which airspeed change affects Total Energy, and increasing it above 100% incr eases the amount.
Vario Off when Motor Running: This option disables the variometer tones when the motor is running, based on the amperage draw of the motor. This is useful for “motor gliders.” The variometer is off when motor current is more
tha n approximately 1.5 amps.



# 7.7 Vector Calibration

The Vector is factory calibrated, and normally no further calibration is necessary. However, user calibration of some

sensors can be performed

. Calibration options are located on
the “ Calibration and Sensor S etup” menu.



## 7.7.1 Electrical Calibration

The voltage and amperage (current) readings for your motor pack, and the voltage readings for your transmitter pack, camera pack and receiver pack (if used) can be calibrated.

These calibrations are performed in the “El ectrical Calibration” menu. For your convenience, all voltages and currents are displayed in re al time on the electrical calibration page, so you

can compare the Vector readings with the readings of your voltage and current meter as you change the settin gs

.
Voltage Calibration: To calibrate voltages, change the “Voltage Factor” for the appropriate voltage. Increasing the factor increases the reported voltage, and vice versa.

Current Calibration: Calibrating the current sensor typically involves just in creasing or decreasing the “Current Sensor Factor” as appropriate.

One additional calibration setting for the current sensor is the “Zero Offset”. The zero offset is chosen to match
the lowest level of current flow that the Vector’s current sensor can detect. Typically, this is about 300 mA (0.3 amps).

# USER GUIDE

77 If your current sensor’s true offset is 300mA, and the current offset is set to 0.3 in the menu , the Vector will always read 0.3 amps when the current draw is less than or equal 0.3 amps, but when t he current climbs above 0.3 amps, the Vector will correctly read that current. If your amp meter shows that you are drawing greater than 0.3 amps when your motor is not running (due to your video camera, video transmitter, the Vector, and
other accessorie s) , but the Vector is reading 0.3 amps, increase this setting until the Vector matches your meter’s reading. Note that an incorrectly set offset will only cause a very slight amount of error, so changing the offset is generally not needed.



## 7.7.2 Altimeter Cali bration

The Vector’s altimeter is factory calibrated. When the Vector has been unpowered for a while, it is normal for a small amount of altimeter drift to occur over a few minutes, as the Vector warms up. When you reset the home position, or when yo u arm your multirotor, the Vector’s altimeter is automatically rezeroed, erasing any drift.

But, if you see your Vector’s altimeter drifting more than a few feet (1

- 2meters) during warmup, and that is causing issues for you, you can calibrate it as follows :

1) Make sure that the weather is not changing, which can cause significant barometric pressure differences in a short period of time. 2) Leave the Vector completely unpowered for at least 30 minutes. 3) Have your transmitter ready, and apply power to the Vector ( do this indoors). 4) Within 1 minute (the quicker the better) navigate to the Calibration and Sensors menu, select the “Altimeter cal (read manual)” item, and click the mode switch. 5) Don’t move the Vector until the calibration process completes (about 3 minute s). 6) The calibration result (pass or fail) will remain in the notification area after the process completes.



## 7.7.3 Pitot Airspeed Calibration

If the optional pitot tube airspeed sensor is being used, and you find that the airspeed readings are too high or low, the "Airspeed Sensor Factor” on the Calibration screen can be used to adjust it. Increase this value if yo ur pitot speed is too low, and vice versa.



# 7.8 GPS Configuration

Several settings for the GPS are provided, on the GPS Configuration menu.



## 7.8.1 Choosing th e GPS Position Display Format

The GPS position can be displayed in 3 formats, controlled by
the “GPS

- On

- screen display format” setting:

t) Decimal degrees ( DDD.DDDDD° ) u) Degrees, minutes ( DDD° MM.MMMM' ) v) Degrees, minutes, seconds ( DDD° MM' SS.S" )

The GPS posit ion display is most useful for letting you locate a lost model by entering the last displayed GPS position into a mapping program (such as Google MapsTM) on your laptop or phone.

Many mapping programs will accept all three formats, but check to see which one s your program supports BEFORE you might need to use it!

# USER GUIDE

78 

## 7.8.2 Changing the GPS Fix Quality Settings

In the “ GPS Configuration ” menu, several options are available for setting criteria for the minimum fix quality required. These criteria must be met befor e the home GPS position is finalized after boot

- up.
Additionally, for multirotors these criteria must be met at all times for GPS flight modes (loiter, etc.) to be
enabled.
For multirotors, allowing for a worse than the factory default GPS signal to be u sed increases the
likelihood of problems during GPS flight modes, such as large amounts of sudden drift during loiter!

Set Minimum Satellite Count: This lets you set the minimum number of satellites that must be in view

. In general, the higher the numb er of satellites, the better the position reliability.

Require 3D GPS Fix: Set this to YES if you wish to wait until a 3D GPS fix is attained.

Set Maximum HDOP: Horizontal Dilution of Precision (HDOP) is a measure of the GPS fix quality. The lower
this number is , the better the fix. The HDOP can vary with a variety of factors, including the position of the satellites in view relative to each other. As a very general rule, HDOP of 2.0 or less is highly desirable. HDOP
less than 1.3 is desirable , but may not always be attainable.

Seconds to Wait post GPS Fix: Set this to a non

- zero value if you wish to specify the number of seconds that must elapse after the GPS signal meets the criteria above, before the home position is finalized. In ma ny cases, even after the GPS reports it has acquired a good fix, waiting for additional time can improve the accuracy of the home position.

Happy Flying!!

# 8 Troubleshooting

Issue Solutions

My multirotor does not hold horizontal position well in
the Loite r flight modes If you are using a high power video transmitter (especially 1.3GHz), try hovering with your video transmitter turned off to see if the issue goes away. If the transmitter is the cause, see the GPS Fix troubleshooting section below.

Make su re your GPS module is getting an unobstructed view of the sky.

Make sure your compass is calibrated correctly.
Try adjusting the “GPS Position Hold” gain in the Advanced Stabilizer Settings menu. We recommend you change this in 10% increments.

My multi rotor does not hold vertical position (altitude)
well in altitude hold modes. Try adjusting the “ Vertical/A l titude Gain ” gain in the Stabilizer Settings menu. We recommend you change this in 10% increments.

RTH: my fixed wing model doesn’t fly home fas t enough

, or flies home too fast Increase or decrease the “Cruise Throttle Position” parameter in the
Advanced Safety Mode menu, or rerun the Receiver Analysis Wizard and set a higher or lower cruise throttle position.

If high winds are causing slow return to home, you can program a minimum RTH ground speed

, by changing the “ Minimum Ground Spd(0 disable) ” parameter under the Advanced RTH menu. If the Vector detects the model is moving slower than this speed, it will increase the throttle from the “Cruise” setting to the “Climb” setting you provided when running the Receiver Analysis Wizard.

I cannot arm or get the motors to spin on my multi rotor. You cannot arm the system while connected to a USB connection. You
must disconnect the USB cable a nd then reboot the Vector.

You must confirm your frame type during your first reboot. After selecting your frame, you will need to disconnect from the USB
connection (if connected) , reboot the Vector and then toggle your mode switch when the message comes up on your video screen to accept your frame type. For this reason

, we recommend at least temporarily connecting a video monitor to the Vector to complete this step. Or, if you are certain you are correct about the frame type, you can reboot the Vector, w ait about 5 seconds, then toggle your mode switch to accept the frame type without verifying it on the video screen (not recommended).

Note that as you hold the stick(s) in the arm position, the motors will pulse or “twitch” twice before the props will co ntinuously spin. You must continue holding the stick(s) in the arm position during this sequence, or the multirotor will not arm. If preferred, the pre

- arming twitches can be disabled by selecting “Allow Fast Arming?” option in
the “Advanced Multirotor” st ick menu, or under “Other Advanced Settings” on the Flight Controller tab in the software.

Be sure you are using the correct arming procedure outlined in section

# USER GUIDE

80 "5.11.4 Arming and Disarming your Multirotor (Multirotor only)", specifically, you only move the throttle/rudder stick and must leave the elevator/aileron stick centered.

Why does my multirotor bounce when landing? Bouncing landings can usually be attributed to a few causes:

1) Pitch/Roll/Yaw Basic Gains are set higher than they need to be (try reducing these gains by steps of 20%) 2) The model has a very high thrust to weight ratio (it's too light) 3) Idle throttle is too high

In general, we recommend that the throttle level when in 2 D No Hold mode should be right around the center point w hen you're hovering. A larger battery, smaller props, lower kV rating, more weight, lower idle throttle or lower pack voltage can all accomplish these things. To assist in troubleshooting, adding some additional weight to the model in order to dampen o ut the bounce will let you rule insufficient weight
in or out.

The motors on my multirotor are not spinning at the same speed, what is wrong? As soon as the multirotor is commanded a positive throttle level (above mid

- point for altitude hold modes, an d above ~5% for non

hold modes ) while sitting on the ground, you will see the motors changing RPMs as its "integrator" functionality is activated. In simple terms, the Vector is constantly re

- trimming the motors so that it will fly accurately even with an imbalanced frame. When it's on the ground

, however, the motors will try to spin up or down until the
multirotor is matching the currently commanded pitch/roll angles from your control stick. The more level your model is, the slower the spin up will be. In addition, as soon as you're flying, the model will quickly trim itself to level.

The Vector has numerous fails afes to try to prevent a rming under
unsafe condition . When you arm your multirotor , you should see all of its props spinning at roughly the same speed. Once you increase throttle from 0%, the motors should all spin up. I t is normal for one

prop to begin gradually spinning up more than the others

. If any prop stops spinning or fails to start spinning when you are at 0% throttle,
then there is like ly a problem with either the Idle Throttle setting or your ESC calibration.

RTH: my multirotor returns home too fast or too slowly Increase or decrease the “ Return Home Ground Speed ” setting in the
Advanced RTH menu. It is recommended to change this set ting in small increments.

RTH /Loiter : My fixed wing
model turns too fast or too slowly toward home, when returning home or in loiter
mode Increase or decrease the “ Maximum Roll for RTH/Loiter” in the Advanced RTH menu. The angle should be increased if th e model is turning too slowly and vice versa. It’s recommended you change this setting in steps of 5 to 10 degrees.
Increase or decrease the “Turn Gain” setting in the Advanced RTH menu. The gain should be increased if the model is turning too slowly,

# USER GUIDE

81 a nd vice versa. It’s recommended you only change this setting after failing to fix the problem by adjusting the “ Maximum Roll for RTH/Loiter ” or if increasing that setting could create a stall risk for your airframe. Adjust this setting in about 10% incr ements.

RTH: My model pitches or rolls (banks) too sharply or too shallowly during RTH. Increase or decrease the “ Maximum Pitch for RTH /Loiter ” and/or

“ Maximum Roll for RTH /Loiter ” settings in the Advanced RTH menu

RTH: My model climbs or
descends too fast or too slowly during RTH Increase or decrease the “ Desired Climbrate ” and/or the “ Desired Descend/Sinkrate ” settings in the Advanced RTH menu

RTH/Loiter: my fixed wing model circles too widely or too tightly around the loiter or home point Increase o r decrease the “ RTH/Loiter Circle Radius ” setting in the
Advanced RTH menu.

See also the steps for troubleshooting if the model turns too fast or too slowly, above.

GPS: I am having trouble getting a GPS fix. Or, once GPS fix is acquired, it is periodic ally lost,
or the GPS position seem s to move around quite a bit when the model is stationary

. Always keep the GPS/MAG as far away from your video transmitter antenna, and your video camera, as feasible.

If you are using a 1.3GHz or 900 MHz video transmitte r, it is probably generating spurious noise on the frequencies used by GPS. A good description of the causes and solutions of this problem is located here: http://www.dpcav.com/data_sheet s/whitepaper_GPS.pdf

. Try testing the GPS with as many devices powered down as possible and then add them back one at a time, and look for GPS degradation. Note: You can connect the video output from the Vector’s "Video Tx" connector directly to a moni tor or goggles to test powering off your video
transmitter.

Audio: I hear static, buzzing or humming only when the OSD is showing information on the
video screen.  Increase your Vector “Black Level” setting in the OSD Setup menu.

 If you don’t have the audio input of your video transmitter connected to anything, try connecting it to the Vector Audio Harness , and plug ging the harness into the Vector ’s audio port

, as described earlier.

Audio: I have set up voice alarms, but am not hearing them, or they are faint.  Verify that “ Mute Voice Alerts ” is set to “No” in the Audio/Variometer Setup menu.

 Increase “ Set Voice Alerts Volume ” in the Audio/Variometer Setup menu if the sound is too low, compared to your microphone
volume.

 Verify that your wiring is correct. Especially, make sure that the audio channel (left or right) that is coming from the Vector is the same one you are listening to on the ground.

Video: I am seeing video “smearing” or lines on th e video screen, that correspond with the Increase your Vector “Black Level” setting in the OSD Setup menu.

82 location of text on the screen.

Video: I am having trouble reading the Vector text through my goggles.  Try increasing or decreasing the “Black Level” setting in the OSD Setup menu.

 Increase th e “ Color Brightness ” in the Color Setup menu.

 If a particular color is hard to read, either set intensity of that color to “High”

, or change your settings to not use that color

, in the Color Setup menu.

 S elect “White” for “Numeric Parameters Color” in th e Color Setup menu. Then, the “White Level” setting in the OSD Setup menu will let you change the brightness of the white text.

I am having problems with my
Vector which I haven’t been able
to resolve otherwise.  Make sure you are running the latest Vect or firmware, as described in the “Firmware Update” section.

 Consider performing a “Factory Reset” on your Vector, which will restore the Vector to factory defaults. This can be done either with the “Factory Reset” button in the software (at the bottom of the screen) or with the option in the Advanced Radio Control stick

menu.

Software: the configuration does not launch, or exits shortly after starting.  Try running the software in Windows XP Compatibility mode

 Try running the software “As Administrator”

The Vector is not detecting my receiver’s S.BUS output. If using S.BUS2TM with the FutabaTM RX R7008SB receiver, be sure you
select FASTTtestTM 18 channel or 14 channel mode s and link to the
receiver from the transmitter’s menu.

My receiver does not turn on

. The Vector does not power your receiver or servos. You will need to

power your receiver and servos as you would in a non

- Vector model, such
as with a stand

- alone BEC, a BEC built into your ESC, or a separate battery

p ack.

Whatever power is provided to your receiver will be routed through the Vector to your servos , via the Receiver Connection Harness . Whatever power is provided by an ESC ’ s BEC will be routed through the Vector to

your receiver and servos.

You can alternatively use the 5 volt tap from t he PSU (if not being used to power a 5 volt camera or video TX) to power your receiver on multirotors.
Please see section 3.5.6
