ZX5 Operations Manual 6

1 Safety

WARNING – The Trimble ZX5 is a sophisticated system. As such: 

*THIS SYSTEM SHOULD ONLY BE OPERATED BY TRAINED PERSONNEL. TRAINING EVENTS 

CAN BE COORDINATED THROUGH TRIMBLE. OPERATING THIS SYSTEM WITHOUT PROPPER 

TRAINING MAY RESULT IN SERIOUS INJURIES AND/OR EQUIPMENT DAMAGE. 

*ALWAYS MAINTAIN LINE OF SITE WITH THE AIRCRAFT WHILE OPERATING. 

*ANY DAMAGE OR INJURY THAT OCCURS AS A RESULT OF MISUSE OF THIS PRODUCT IS 

SOLELY THE OPERATOR’S RESPONSIBILITY.

To provide optimum performance, your Trimble ZX5 is powered by a Lithium Polymer (LiPo) battery 

pack. The same properties that make these batteries extremely powerful and lightweight also make 

them dangerous if handled incorrectly.

CAUTION – Read and understand all information regarding to battery usage and charging 

before first use.

*Refer to the “Trimble ZX5 Lithium Polymer Battery Manual For Maintenance & Use” for 

more detailed information and instruction.
ZX5 Operations Manual 7

2 System Features

The Trimble ZX5 is a radio controlled, electric powered aeronautical vehicle capable of vertical take-off 

and landing. Built with the latest electronic sensors and GPS-receivers, the aircraft is capable of selfstabilization. Thus the Trimble ZX5 can autonomously fly to pre-set waypoints and hold its position, even 

under windy conditions.

The aircraft can be configured with different payloads and position them in various ways. Considering 

this, it is possible to achieve stunning video recordings and images from completely new angles. The 

high-performance control unit in the aircraft provides unprecedented accuracy. The aircraft can be 

controlled by a modern radio control unit or an Apple iPad. To assist with recurring operations, the 

system can load pre-identified waypoints and fly them semi-automatically.

For advanced operations, complex missions can be planned on a computer and uploaded to the aircraft. 

With this feature, very large or complicated areas can be surveyed in order to create three-dimensional 

maps with extreme precision. 

Optionally, the aircraft and the payload can be controlled independently from two different control 

units. The pilot can concentrate on flying while the payload operator makes adjustments for the ideal 

camera view and provides the best possible data.

In the following, we want to explain the system with all its features.

4.1 Orientation

The ZX5 is built symmetrically to ensure balance and stability. To identify the front of the aircraft, locate 

the two extension arms with orange brackets. 

4.2 Propellers

The ZX5 can be equipped with either rigid or foldable propellers. Please note that each propeller will be 

configured to spin in either a clockwise or counter-clockwise direction. Take care to identify the 

direction of each propeller and make 

sure to install the clockwise rotating 

propellers on the clockwise rotating 

motors and the counter-clockwise 

rotating propellers on the counterclockwise rotating motors.

Figure 2: Propeller Mounting

Figure 3: Propeller Configuration
ZX5 Operations Manual 10

CAUTION – Failure to attach the correct propeller configuration to the corresponding motor 

will result in uncontrolled flight. Equipment damage may occur. 

To keep the aircraft’s overall weight down, the propellers are crafted to be very light. As a result, they 

are susceptible to damage if mishandled. Avoid contact with other objects during transportation and 

flight.

WARNING – Operating an aircraft with cracked or damaged propellers may result in 

equipment damage and/or personal injury. Never fly with a damaged propeller. Always 

replace it with a new one before operating..

CAUTION – Propellers require proper balance at all times or unstable flight may occur. If 

vibrations are observed, land the aircraft immediately and inspect all propellers for proper 

installation. Unbalanced propellers can cause blurry imagery and if left uncorrected will 

eventually result in uncontrollable flight and equipment damage.

CAUTION – Do not mix the propeller configurations you install on your ZX5 (rigid vs foldable). 

This will result in the aircraft being unbalanced. (See previous Caution.)

4.2.1 Foldable Propellers 

The foldable propellers are pre-installed by the manufacturer. For inspection and maintenance please 

refer to the “Maintenance Manual”.
ZX5 Operations Manual 11

CAUTION – Do not exchange single blades between propeller units. Failure to comply may 

result in equipment damage. 

*Each foldable propeller is a unit made of 2 blades and a centre piece. The propeller unit is 

balanced by the manufacturer to ensure stable operations at 8.000 rpms.

4.2.2 Rigid Propellers

Prior to using rigid propellers the system MUST first be aligned to a new set of parameters for engine 

control. The new set of parameters can only be uploaded by the manufacturer.

CAUTION – Never operate the ZX5 using rigid propellers without first confirming the system 

has been properly configured. Failure to comply may result in equipment damage. 

4.3 Power Supply (LiPo Battery Pack)

The Lithium Polymer battery is characterized by its low weight, high capacity and high power output. 

The ZX5 is operated by two high-power batteries connected in parallel. To get the best performance and 

lifetime, the two batteries should always be used together. However, in this way, the pair of batteries is 

only as good as the lesser functioning battery. The batteries are fixed with the hook-and-loop tape to 

the airframe and are then connected with the yellow plug.

Figure 4: Battery packs
ZX5 Operations Manual 12

Figure 5: Mounting the battery pack

The correct handling of the batteries is essential to delay the inevitable aging of the battery cells. With 

time and use the voltage level of the cell is reduced and the inner resistance is increased i.e. the 

batteries deliver less current. In order to delay the aging process the LiPo batteries should be used 

regularly (approx. 1x per month).

Life Expectancy

 The voltage in the individual cells should always be between 3.2 V and 4.2 V. Excess or low voltage 

causes damages beyond repair.

 Charge the LiPos shortly before use (max. 1 - 2 days before).

 Do not recharge LiPos if they are still full.

 Do not fly with a used battery, always recharge used batteries beforehand.

 Avoid transport or storage below 10 degrees Celsius (50 degrees Fahrenheit) (during flight the 

battery stays in temperature due to the current flow).

Storage

 Store the LiPos with a rest capacity of 20 - 30 % (if the batteries are full and you don’t need to use 

them for an unknown count of days, it is better to discharge them to the storage capacity level).

 Store the LiPos at about 15 – 20 degrees Celsius (59 – 68 degrees Fahrenheit).

Charging/Discharging

 Supervise the charging and discharging at any time (misuse or malfunction of the charger and 

connectors can cause fire).

 Charge always with connected balancer cable.

 Use only faultless charging cables.
ZX5 Operations Manual 13

 In low outdoor temperature (< 10 degrees Celsius, < 50 degrees Fahrenheit) the battery capacity 

reduces itself down to about 50 %.

General

 Never short-circuit a LiPo battery.

 Do not discharge below 3.2 V per cell.

 Do not recharge directly after use. Let them cool down first.

 Make sure that the charging device is well ventilated.

 In case of a fire do not extinct with water, use sand.

 Do not use deformed or damaged batteries.

LiPo batteries can be volatile if not used, stored or maintained properly. Please refer to the LiPo Manual

for a more in-depth overview of battery use and general precautions that should be taken. 

CAUTION – Never separate the battery packs. Failure to comply may result in battery failure 

and subsequent equipment damage. 

4.4 Dome

The dome protects the electronic components from humidity, dirt and debris. 

Removal of the dome is required for the following:

 Updating the firmware.

 To plug in the cables of the servos.

 To plug in the cable of the camera trigger.

To remove the dome, rotate the cap counter-clockwise and lift it up.

CAUTION – Always unplug the battery before removing the dome. Failure to comply may 

result in equipment damage and/or personal injury.
ZX5 Operations Manual 14

4.5 Circuit points

The ZX5 has numerous connector pins:

 6x 3-pin connector for up to 4 servo motors and one camera trigger .

 Socket for video access.

 Socket for firmware update.

 Socket for mission upload cable

4.5.1 Servo connectors

The connectors for the camera mount servos (if the mount has servos and not brushless motors) are 

located under the dome. The links are consecutively numbered from left to right as displayed:

1. Roll compensation

2. Pitch compensation

3. Trigger for camera

4. without function

5. without function

6. without function

 Figure 6: Servo connectors

CAUTION – Always disconnect the power supply before plugging in/unplugging the servo 

cables. Failure to comply may result in damage to internal electrical components. 

4.5.2 Firmware Update (MCU1, MCU2)

To update the firmware, connect the mainboard with a computer by using a special cable. There are two 

processors on the mainboard. Depending on which processor requires the update, the cable has to be 
ZX5 Operations Manual 15

plugged in directly or turned 180°. If the cable is improperly configured, the update will not be 

successful. 

Make sure to keep the firmware of the ZX5 up to date. We are always trying to improve the software 

and features. You can stay inform on all the new updates in your own account on our website. There you 

can also find the instruction on how to complete updates correctly.

CAUTION – Avoid contact with the electronic devices and the conducting paths on the board. 

Failure to comply may result in equipment damage.

Figure 7: Plug for firmware update

4.5.3 Mission Upload Cable Port

The Mission Upload Cable Port (depicted in the figure below) allows for connection of the Mission 

Upload Cable to upload self-defined missions created with the software “Ground-station”.

Figure 8: Mission Upload Cable Port
ZX5 Operations Manual 16

4.6 Remote control receiver with antenna

The remote control receiver works in a range of 2.4 GHz via a dipole-antenna to keep interference as 

low as possible. The yellow antennas are secured by a flexible hose.

Figure 9: RC-Antenna

Note: Pay attention to never bend the antennas. They should be aligned in a straight line and in a 90° 

angle to each other. Otherwise the range of the remote control will be degraded.

4.7 Video Transmitter with Antenna (Full Business 

Upgrade)

The video transmitter is installed into the camera gimbal. It works in a frequency range of 5.8 GHz. It is 

connected with a special video antenna as shown in the figure below. The antenna can be adjusted by 

turning it at the plug. You may need to make several small adjustments to the antenna position in order 

achieve the best possible connection. This will also depend on the external conditions and the camera in 

use (shadowing effects).

 
ZX5 Operations Manual 17

Figure 10: Video transmitter antenna

4.8 Flight Recorder

On the flight-control-panel under the dome there is a slot for a micro SD card. The flight recorder uses 

the micro SD card to store all system and sensor data during the flight. If you should have problems with 

your ZX5 you can import the flight data on the SD-card to your computer, save it and send it to the 

manufacturer for analysis. Special software is required to read the micro SD card. It is provided by the 

manufacturer. To get to the board you have to remove the dome. Press onto the card to release it. 

Figure 11: Flight recorder/micro SD card slot

Note: The data format is only readable with special software. Never process any activity (e.g. copy 

data, format etc.). The required material will be destroyed and is not usable for the UAV anymore.

The ZX5 can only be started when a micro SD card is plugged in. If you lose your card, or it gets 

damaged, contact the manufacturer to get a new one.

If you have problems it is best to contact the manufacturer first.

Note: In the event of a crash or malfunction, do not power on the aircraft afterward. This can cause 

overwriting of the last flight’s data and it can no longer be analysed to determine the malfunction.
ZX5 Operations Manual 18

4.9 Acoustical Signals

On the frame of the UAV there is a signal transmitter that gives acoustical signals to report different 

conditions. In addition, every motor gives a “buzz” after power-up. 

Acoustic signals after power up:

Legend: _ means a short beep, __ means a long beep

_ __ _ _ All Operations OK

_________ Warning: SD-card or GPS not connected 

_ _ _ _ _ _ _ _ _ etc. Warning: can’t receive remote control signal

__ _ _ _ _ Aircraft isn’t level

__ __ _ _ _ Malfunction: Motor switch is activated without minimum 

throttle or Coming Home is still active 

__ __ _ _ _ Aircraft is disabled: register with the manufacturer *1

Acoustic signals during flight:

_ _ _ _ _ _ _ _ etc. Alarm: Battery voltage too low

In addition there are more signals that indicate malfunction. Contact the manufacturer if you hear 

unusual signals. As a precaution in this case do not perform any flights furthermore.

Note: If there is an acoustic signal for low battery voltage during the flight, you cannot start the 

motors again after landing until you have disconnected the battery. 

*

If the ZX5 is not registered, it is possible to perform 10 demonstration flights. After that the aircraft is 

disabled. To unlock the aircraft contact the manufacturer.
ZX5 Operations Manual 19

5 Camera Gimbal 

The camera mount provides a stable platform to transport the cameras during flight. It provides a 

straight and stable field of view, even if the aircraft isn’t level during flight. The roll and yaw axis are 

controlled by brushless motors and an independent stabilising unit. The camera can be adjusted 

manually to define the needed pitch and focus on the desired object. 

Figure 12: Camera gimbal

The gimbal is powered on by its own power switch. It is located at the side of the gimbal. In addition to 

the power switch, there is a small push button for calibration. See the maintenance manual for more 

information on calibration.
ZX5 Operations Manual 20

6 Base Station

The base station is the main control unit. It consists of a remote control and a monitor with video 

receiver. The pilot operates the ZX5 with the remote control (RC). It is linked to the ZX5 with a 2.4 GHz 

radio contact. It receives and shows the telemetry data of the ZX5 (downlink). The remote control 

analyses the received telemetry data and sends acoustical messages to the pilot about the state of the 

ZX5 components (e.g. battery and GPS state, flight mode, etc.). 

In addition, it can send data and commands (e.g. geographical coordinates and waypoints) to the ZX5 

(uplink). The ZX5 can be operated with two kinds of remote control: Jeti DC16 or Jeti DS14. 

On the monitor the pilot can see the live view of the on-board camera. The monitor (with the video 

receiver) is powered by a LiPo battery.

7.1.4 Flying functions (flight mode)

The ZX5 comes with different flying functions. It is possible to fly it completely manually or fully 

automatic. Some functions will be explained in detail in the chapter “Tutorials”.

Note: There are different GPS-functions available for your ZX5, which can be bought and activated.

This means, that if applicable not all described functions can be used with your ZX5. Look in your 

contract of purchase, to know which GPS-functions you have bought. The manufacturer will inform 

you about the current available function packages.
ZX5 Operations Manual 24

ATTENTION – Some GPS-functions refer to the “starting point”. This means the point where 

the ZX5 has identify its GPS-position, after attaching the batteries (also known as the Firstfix-position). Generally this is the actual start position.

ATTENTION – If you start the ZX5 and take off before it has time to define its position, it will 

assign a position in flight. This will then be used as the “starting position”.

Additional Functions at DC16 (Full Business upgrade)

The automatic flight functions can be activated in multiple levels with the switch “sh” and “si”.

A higher level needs the activation of the levels below (e.g. GPS only works if the compass works, the 

compass only works if the altitude control works, etc.).

Figure 16: Flight mode switches

The following listing starts with the lowest automatic level:

Manual control

Manual Flight Control

In this mode all the dynamic flight characteristics of the ZX5 can be fully demonstrated. The control is 

very difficult.

Activation: pull the switch “si” backward (switch “sh” accordinglyl)

Performance: All flight stabilizing functions are deactivated. The pilot has to steer height, position and 

direction completely manual.

WARNING – Operation in manual mode should only be conducted by experienced 

R/C operators or personnel trained in manual operations. Failure to comply may 

result in equipment damage and/or personal injury. 

Height control

Automatic Height Control

In this mode the dynamic flight characteristics of the ZX5 can be fully demonstrated as the altitude is 

maintained automatically.
ZX5 Operations Manual 25

Manual control

Activation: Toggle the “si” switch to the middle position (switch sh accordingly)

Performance: The pilot controls the position and direction. The altitude is kept automatically, when 

the left stick is positioned in the middle.

WARNING – Operation using “Height control” should only be performed by 

advanced pilots. In this mode the ZX5 is susceptible to winds and may drift and/or 

rotate if the pilot doesn’t counter these movements. 

Mag control

Automatic Direction By Magnetic Field Sensor (Compass)

Activation: Toggle the “si” switch forward (switch “sh” backward)

Performance: The ZX5 keeps the direction and height automatically. The pilot has manual control over 

position..

WARNING – Operation using “Mag Control” should only be performed by advanced 

pilots. In this mode the ZX5 is susceptible to winds and may drift and/or rotate if the 

pilot doesn’t counter these movements.

Manual Flight

Flight Without GPS-Functions

Activation: Push the switch “sh” backward (switch si forward)

Performance: In this mode all GPS-functions are deactivated.

This mode is identical to the mode “Mag control“.

GPS Position Hold

Automatic position stabilisation by GPS

In this mode the movement of the ZX5 is controlled by GPS. The speed is limited. Acceleration and 

deceleration are carried out damped. If hovering in one position, it will be held automatic. In flight the 

flight direction is maintained. The ZX5 compensates for wind automatically. 

Activation: Put the switch sh in the middle position (switch si forward)

Performance: The ZX5 maintains the position and direction even in windy situations.

GPS Coming Home

Automatic return flight to the starting position

This mode is useful in case of loss of orientation by the pilot or if the mission is completed and the ZX5

should come back to the starting position to land. 

Activation: Push the switch sh to the top (switch si to the top)

Performance: The ZX5 flies back to the starting position 

Cancelation: This function can be cancelled by slightly moving either the left or the right stick. The ZX5

changes into the “Position-Hold“ mode.

CAUTION – Crash against barriers

Risk of damage! In flight mode “Coming Home” the ZX5 always takes the shortest and 

direct way back to its starting point. The pilot has to make sure it flies in an altitude 

with no barriers.
ZX5 Operations Manual 26

Note: If a problem should occur during the flight (a propeller is damaged etc.) the ZX5 may no longer 

be able to hold its GPS location. If this occurs, deactivate the GPS-function and activate the “Manual 

Flight” mode and initiate a landing.

WARNING –The ZX5 will automatically switch off the GPS-functions if either of the following 

conditions exists: 

Satellite receiving power drops below 6 satellites. 

The position accuracy is above 8 m. 

In this case the pilot has to initiate manual control. 

Possible causes: satellite problems, atmospheric disturbance, signal influence by other 

radio sources, etc.

7.1.5 Other Flying Functions 

There are further flight functions that you can apply in different situations that can help you accomplish 

your tasks.

Auto start

Automatic Start Function

Requirement: The ZX5 is positioned on the ground with motors are running at idle.

Activation: Push the “sc” switch forward

Performance: The ZX5 increases throttle and takes off, climbing to approx. 2 m.

Auto landing

Automatic landing function 

Requirement: The ZX5 is in flight.

Activation: Pull the “sc” switch backwards

Performance: The ZX5 lands automatically, motor speed decreases to idle.

Attention: Push the throttle stick to full down immediately after landing. Under certain circumstances, 

for safety reasons, the motor speed will increased again after 2 sec.

Note: Once the ZX5 touches down, you shouldn’t see any sideways movements. This can cause the 

aircraft to overturn. To eliminate this use the GPS-position-hold mode or keep the ZX5 in position 

manually. 

If the ZX5 is still over 10 m high it will descend faster, below 10 m the descent rate slows down.

Cancelation: This function can be cancelled by slightly moving the left stick.

CAUTION – If initiating an “Auto landing” on hilly terrain where the chosen landing place is 

greater than 10 m higher than the starting position, it is possible that the ZX5 will descend

too fast and touch ground with too much speed. This may result in equipment damage. In 

this case it is better to land manually.
ZX5 Operations Manual 27

Go Ahead

Automatic Alignment Function

This function is useful in the event the pilot doesn’t remember or can’t see in which direction the ZX5

is aligned. It turns the ZX5 once-only so that he has the starting point behind him. This means that the 

right-stick-steering conforms to the resulting movement of the ZX5.

Requirement: The ZX5 is flying and a minimum of 20 m away from the starting point.

Activation: Pull the “sb” switch backward

Performance: The ZX5 turns in place so that the starting point is oriented behind it.

Easy Move

Extended Automatic Alignment Function

This function helps the pilot to maneuver the ZX5 more easily. To keep the steering more intuitively, 

the alignment of the ZX5 is not considered anymore during conversion of the steering commands. This 

means that the ZX5 always flies in the direction in which the right stick is shifted regardless of where 

the ZX5 is located. The imaginary line between the starting point and the ZX5 equals the stick axis 

(forward – backward) of the right stick. 

Requirement: The ZX5 is flying and a minimum of 20 m away from the starting point. 

Activation: Push the “sb” switch forward 

Behaviour outside the 20 m radius: From the view of the pilot the ZX5 always moves equivalent to the 

movement of the right stick regardless in which position the ZX5 is directed. 

Example 1: Right stick to the front: the ZX5 always flies straight away from the starting point.

Example 2: Right stick to the back: the ZX5 always flies straight towards the starting point. 

Example 3: Right stick to the right: the ZX5 flies spirally around the starting point. 

Behaviour inside the 20 m radius: Inside the 20 m radius the ZX5 behaves slightly different to avoid 

the problems of the GPS inaccuracy. The directing of the ZX5 stays the same as it was on the point of 

activation. 

Example 4: The function is activated inside the 20 m radius, while the ZX5 is directed to the NW 

(45°). Right stick pushed forward: the ZX5 flies towards the NW. After passing the 20 m radius it 

carries on flying in this direction, because it behaves like it is described in example 1. 

Example 5: The function is activated inside the 20 m radius, while the ZX5 is directed to the NW 

(45°). Right stick pulled backward: the ZX5 flies towards the SE (225°/-135°). After passing the 20 

m radius it changes direction and flies backwards towards the starting point like it is described in 

example 2.

Example 6: The function is activated inside the 20 m radius, while the ZX5 is directed to the NW 

(45°). Right stick to the right: the ZX5 flies towards the SW (135°). After passing the 20 m radius it 

changes direction and flies spirally around the starting point like it is described in example 3.

Behaviour while entering the 20 m radius: When the ZX5 is flying into the 20 m radius, the current 

orientation is fixed set. That has the positive result that the ZX5 doesn’t change direction while 

entering (if the right stick is held continuously).

Behaviour while exiting the 20 m radius: When the ZX5 is flying out of the 20 m radius, the front is at 

the end of an imaginary line from the starting point to the ZX5. If applicable the ZX5 will change 

direction.

7.3 Announcements

Some conditions and events are announced via voice output. If there is a lot of noise around you, you 

can use earphones to ensure that you hear all notifications. The radio control provides a 3.5 mm 

connection. 

After connecting the ZX5 batteries, all motor control units give an acoustic signal (peep), followed by the 

announcement of the current flight mode. During the following flight status further announcements are 

made according to the events:

Announcement Significance

GPS OK The GPS satellite reception is very good. The GPS functions can be used.

GPS control The flight mode “Position-Hold“ is set. The ZX5 keeps its position 

automatically.

Height control The flight mode “Height Control“, which holds the height of the ZX5

automatically, is set.

Mag control The flight mode “Mag Control“, which holds the alignment of the ZX5, is 

set.

Coming home The “Coming-Home“ function is activated. The ZX5 flies back to the 

starting point.

Easy Move Mode The “Easy Move Mode“ is activated.

Set rear orientation The “Go-Ahead“ function is activated. The ZX5 aligns itself.

POI Mode The “POI” mode is activated.

Waypoint The “Waypoint” mode is activated.

Auto start The ZX5 starts automatically.

Auto landing The ZX5 lands automatically.

Attention: Emergency 

landing

The ZX5 conducts an emergency landing. The pilot can still readjust the 

position and the height.

Warning: No flight 

recorder

There is no SD-card in the flight recorder.

Warning: No GPS The reception of the GPS-satellites is very bad. The GPS functions are 

deactivated. 

Note: The ZX5 is flying in manual mode, the pilot has to hold the 

position.

Warning: Low battery The battery voltage is reaching minimum level. Pay attention to the 

voltage and make sure to land the ZX5 before it reaches a voltage of 3,5V 

per cell (that equals 14.0 V for a 4S battery).
ZX5 Operations Manual 36

8 Video Receiver (Full Business Upgrade)

The video receiver works independently from the rest of the RC functions. It has a separate electrical

power supply and receives the video signal direct from the ZX5. It reproduces the picture on the 

monitor. The complete package (receiver, monitor, battery) can be either fixed to the remote control or 

onto a tripod. To display the picture you have to attach the battery and switch on the monitor. 

If the battery capacity gets too low a red LED will illuminate. This is located on the bottom left corner of 

the monitor front side. 

Note: The battery type is LiPo battery. Make sure not to discharge the battery below 3.2 V per cell 

(equals 9.6 V for the 3S battery). Please consider the general guidance for all LiPos as described in 

chapter 4.3 of this manual, to ensure a long life expectancy.

ZX5 Operations Manual 37

9 Emergency Functions

The system possesses various emergency functions. 

9.1 RC-Loss (Remote Control Loses Contact)

9.1.1 RC-Loss in Manual Flight Mode With GPS Reception 

The ZX5 automatically goes into “GPS position hold”, waits 20 seconds and then conducts an emergency 

landing. When it touches ground you have to switch off the motors manually. 

9.1.2 RC-Loss in Manual Flight Mode Without Gps Reception

The ZX5 automatically conducts an emergency landing. When it touches ground you have to switch off 

the motors manually. 

9.1.3 RC-Loss in GPS Flight Mode

The ZX5 waits 20 seconds and then conducts an emergency landing. When it touches ground you have 

to switch off the motors manually. 

9.1.4 RC-Loss in WP Flight Mode

The ZX5 waits 20 seconds and then flies directly to the starting point (coming home). Then it lands 

automatically. When it touches ground you have to switch off the motors manually. 

Note: Even when the emergency mode is active the drone can be steered at all times.

As soon as the RC picks up a signal again, the procedure is cancelled. The ZX5 can be operated as usual.

9.2 Battery Low Voltage

If the battery voltage drops to “very low” the ZX5 automatically activates the “position-hold” mode and 

then conducts an emergency landing. The ZX5 is still controllable. When it touches ground you have to 

switch off the motors manually.

The very low voltage limit is 3.3 V per cell. That equals 13.2 V for a 4S battery.
ZX5 Operations Manual 38

10 Flight Time

The flight time depends on the used battery capacity, the weight of the battery, the weight of the load 

and the outside temperature. It can vary between several minutes up to an hour. 

You can ascertain the flight time for your ZX5 with camera equipped by letting initiating a hover in place 

at a 5m altitude until the battery voltage drops to 14.0V. That is your maximum flight time (this may be 

reduced depending on the flight dynamic and the age of the battery).
ZX5 Operations Manual 39

11 Charging

13 Tutorials

These tutorials will help you to get to know the various complex functions of the ZX5 and to learn how 

to operate the system effectively. Before you start, read the safety precautions carefully.

13.1 Safety Precautions 

WARNING – Before starting the motors ensure all personnel and objects are at a safe 

distances from the ZX5; a minimum of 3m.

WARNING – If the propellers are rotating, do not grab to the ZX5. Ensure all other persons do 

not grab to the ZX5. Do not leave the ZX5 unattended with the battery connected. Always 

disconnect the battery when not flying.

WARNING –

 Do not fly near people on the ground or objects in the air.

 Do not fly outside on rainy or windy days or at night.

 Do not fly near high tension lines, electrical substations, high structures or 

communication facilities.

 Never fly this aircraft where damage to property or injury to persons may result if loss 

of control occurs.

 Do not fly over gathering of people.

 Always fly in sight with the ZX5.

 Avoid flying over traffic on the ground.

 Always be prepared to make an emergency landing, without endangering others or 

damaging their properties.

 If you don’t have any experience with model helicopters or model multi-rotors, 

practice with a flight simulator on the computer.

CAUTION – Never fly without an industrial insurance and a special aviation liability 

insurance! We recommend taking out a comprehensive insurance policy. We cannot 

guarantee that a crash due to a mistake by the pilot or technical problems will never occur.

WARNING – Always inspect the ZX5 closely after a hard landing or a crash. A crooked arm or 

motor, for example, can cause unstable flight characteristics. If you are unsure contact a 

Trimble service station!
ZX5 Operations Manual 50

13.2 Position Hold, Flight in GPS Mode 

Purpose: 

Learning to fly the ZX5 with GPS, compass and altitude control.

Environmental Conditions: 

Little up to no wind, lots of space, no obstacles, even and soft ground with low vegetation.

Degree of Difficulty:

Simple

Switch Settings:

Remote control DC16:

 si: Mag control (forward)

 sh: GPS-Position-Hold (middle position)

Remote control DS14:

 se: GPS-Position-Hold (middle position)

sc: Neutral (middle position)

sb: Neutral (middle position)

Process:

 Start motors.

 Start: accelerate, let the ZX5 climb vertically to about 5m. (Make sure that the skids don’t get 

caught in vegetation.)

 Practice flying in all directions. 

Observe how the movement of the stick is interpreted by the ZX5. Try flying various figures; circle, 

triangle, rectangle, figure eight, etc. 

Try a different method: only use the right stick to fly forward and the left stick to steer the direction. 

Turn the ZX5 after a couple of meters. You should end up at the starting point.

 If you need a short brake or lose the orientation, just let go of the sticks. The ZX5 will immediately 

keep its position and hover even if it is windy. 

 Observe the battery voltage and the flight time. Consider that the landing takes a couple of minutes 

so plan your flight accordingly.

 Landing: reduce the acceleration slowly and attempt to descend. Within a few centimetres of 

touchdown take the throttle away completely and switch off the motors immediately after touching 

the ground. You can also use the auto-landing function (only with integrated camera).

Increase the degree of difficulty:

a. Perform this exercise in slightly windy conditions. 

b. Turn the ZX5 90/180/270 degrees and continue a controlled flight path. 
ZX5 Operations Manual 51

13.3 Start, Hover and Land Manually

Purpose: 

Learning how to fly the ZX5 without GPS functions, but with compass and altitude control. You should 

repeat this exercise until you can start, land and fly confidently. 

Environmental Conditions:

Remote control DC16:

 si: Mag control (forward)

 sh: Manual flight (backward)

Remote control DS14:

 se: Manual flight (backward)

sc: Neutral (middle position)

sb: Neutral (middle position)

Process:

 Start motors.

 Start: accelerate, let the ZX5 climb vertically up to about 5m. 

 Practice flying in all directions without turning the ZX5. 

 If you need a short brake or lose your orientation, activate the GPS position hold function (DC16: 

switch si in the middle position/ DS14: switch se in the middle position). The ZX5 will hover, 

holding its position and you can relax. 

 Landing: reduce the acceleration slowly and attempt to descend. Within a few centimetres of 

touchdown take the throttle away completely and switch off the motors immediately after touching 

the ground. 

Increase the degree of difficulty:

a) Perform this exercise in slightly windy conditions. 

b) Turn the ZX5 90/180/270 degrees and continue a controlled flight path.

Note: Even if flying with GPS easier, always practice flying manually as well. There are different 

reasons that the GPS could be interrupted (satellite problems, atmospheric disturbances, other radio 

transmitters, etc.). 
ZX5 Operations Manual 52

“se” (DS14). 
ZX5 Operations Manual 55

13.7 Easy Move

Purpose:

Learning how to use the easy move mode. For this we will imagine the following situation: You want to 

film a car driving on a straight road. The car should approach from behind, pass the ZX5 and then drive 

away to the front. The ZX5 should fly slower than the car, parallel next to the road. The difficulty is flying 

the ZX5 straight on and at the same time aligned with the car. That is made easier with the easy move 

mode. 

Degree of Difficulty: 

Simple

Switch Setting:

Remote control DC16:

 si: Mag control (forward)

 sh: GPS-Position-Hold (middle position)

Remote control DS14:

 se: GPS-Position-Hold (middle position)

sc: Neutral (middle position)

sb: Neutral (middle position)

Process:

 Choose a starting point at the desired distance to the road, about 30m before the point where the 

recording should start. 

 Start the ZX5 (when GPS ok).

 Align the ZX5 along an imaginary line parallel to the road. 

 Activate Easy Move. Push the “sb” switch forward, the current direction is now to the front, inside 

the 20m radius. Outside the 20m radius the front is always on the imaginary line from the ZX5 to 

the starting point. 

 Bring the ZX5 into the height you want. 

 Align the ZX5 backwards to the car. 

 Start the recording of the video image.

 Fly parallel to the road in the desired speed by simply pushing the right stick forward.

 At the same time turn the ZX5 with the left stick so that it is always aligned to the car. 

 After 150m fly the ZX5 back towards you by simply pulling the right stick backward or using the 

coming home function. 

 Land the ZX5.

13.8 POI-Mode (Full Business Upgrade)

Purpose:

Learning how to use the POI function. For this we will imagine the following situation: You want to fly 

around a tower in a defined non-varying distance and take pictures of it from all angles. 

Degree of Difficulty:

High

Switch Setting:

Remote control DC16:

 si: Mag control (forward)

 sh: GPS-Position-Hold (middle position)

Remote control DS14:

 se: GPS-Position-Hold (middle position)

sc: Neutral (middle position)

sb: Neutral (middle position)

Process:

 Start the ZX5 (when GPS ok).

 Fly exactly above the tower top (use the camera, which is directed vertically down, as help).

 Set this position as POI in the extended menu.

 For POI height set half of the height of the tower to record the total tower.

 Fly to the point where you want to start the recording of the video image. 

 Start the POI mode (in the extended menu).

 Start the recording of the video image.

 Fly around the tower at your desired speed (simply by pushing the right stick to the left or the right 

for the whole time). 

 Stop the recording of the video image.

 Deactivate POI mode (in the extended menu).

 Land the ZX5.

Note: The POI position is only stored as long as the ZX5 has power. If you change the batteries you 

have to set the POI again.
ZX5 Operations Manual 59

13.9 Flying Without Compass (Only Possible With RC 

DC16)

You can deactivate the automatic alignment function (compass) by toggling the “si”switch to the middle 

position (only DC16). If you fly without compass, all GPS functions will not work. During the flight, it is 

possible that the ZX5 will turn itself due to wind or torsional moments. Try to compensate this manually. 

Observe the direction of the ZX5 closely, so that you don’t lose the orientation.

13.10 Flying Without Height Control (Only Possible With 

RC DC16)

You can deactivate the automatic height control by pulling the “si” switch backward (only DC16). If you 

fly without height control, all GPS functions and the compass will not work. In this mode you have to 

command height, direction and position manually. This is the most complex flight mode. It is

recommended that only experts use it.

DANGER – If you switch the height control on or off during flight, it can cause an increase or 

loss of height (depending on the position of the throttle stick). You have to regulate the 

ZX5 by using the throttle stick. 

Change the height control only if you have enough space over and under the ZX5, so that 

you have time to get accustomed to the new control method.

13.11 Calibrating The Compass

The compass only has to be recalibrated in exceptional cases. Generally the calibration from the factory 

is sufficient.

If you notice that the ZX5 doesn’t fly directly to a waypoint, but flies around it, it can mean that the 

compass is not calibrated correctly.

DANGER – If the compass is calibrated wrong, the ZX5 cannot fly correctly. This may result in 

equipment damage or personnel injury.

13.11.1 Testing The Calibration of The Compass

You can test the correct calibration of the compass:

Take the ZX5 outside to a place without metal within a radius of a couple of meters.

 Put the ZX5 on the ground and adjust it with the help of a commercially available compass towards 

the north. 

 On the display of the remote control, telemetry data page 1, you should see a compass data of 

about 0°. The tolerance is +/-2 degrees. 

 Tilt the ZX5 slightly to the front but keep it facing north. The display should show 0°.

 Stand it back straight then tilt it to the left. The display still show 0°.

 Turn the ZX5 90° to the right. The display now has to show about 90°.

 Turn the ZX5 again 90° to the right. The display now has to show about 180°. 

 Turn the ZX5 again 90° to the right. The display now has to show about -90°.

If one compass point isn’t displayed correctly (more than +/- 2° off), the compass has to be calibrated 

(see the next chapter). 

13.11.2 Calibrating the Compass

How to calibrate the compass:

 Go into the extended menu and choose: “Calibration - Compass“

 Press the menu button 3 (arrow down) to display: “Rotate around the Pitch-Axis“

 Now the X-sensor is being calibrated. 

 Lift the ZX5 up, align it towards the north and turn it around its pitch-axis. You will hear a signal 

(peep). Now turn the ZX5 around this axis (at least one complete turn) and keep turning it until the 

signals stop. At the same time move the ZX5 slightly to the left and right (about +/- 10 degree). 

 Press the menu button 3 (arrow down) again to display: “Rotate around the Roll-Axis“

 Now the Y-sensor is being calibrated.

 Lift the ZX5 up, align it to the north turned 90° and turn it around the roll-axis. You will hear a signal 

again (peep). Now turn the ZX5 around this axis (at least one complete turn) and keep turning it 

until the signals stop. At the same time move the ZX5 slightly to the left and right (about +/- 10 

degree). 

 Press the menu button 3 (arrow down) again to display: “Again around the Roll-Axis“

 Now the Z-sensor is being calibrated.

 Lift the ZX5 up, hold it just like before and turn it again around the roll-axis. You will again hear a 

signal (peep). Now turn the ZX5 around this axis again (at least one complete turn) and keep turning 

it until the signals stop. At the same time move the ZX5 slightly to the left and right (about +/- 10 

degree). 

 Press the menu button 3 (arrow down) to display: “Offset (XYZ)“

 Press the menu button 3 (arrow down) to display: “Scale (XYZ)“

 Test the calibration as described in the previous chapter. 

 If the display differs in just one of the four points of the compass, you have to repeat the whole 

procedure.
