Introduction 

DJI iOSD is specially designed for DJI autopilot system during the FPV flight or other aero-modeling activates. DJI iOSD

can transmit video and iOSD information in real time, which will help you to obtain the aircraft status information during a

FPV flight. It can display power voltage, flight velocity, height, distance from the home point, horizontal attitude, GPS 

satellite number, etc. iOSD and video information are superposed on the receiver, making iOSD data clearly visible and 

bringing you a more involved flight experience.

DJI iOSD should be used in conjunction with a DJI autopilot system. It supports two video input sources under PAL or 

NTSC mode, which can be selected remotely by an R/C transmitter switch. The R/C TX switch can also change the 

wireless video transmitter channel remotely when user uses the wireless video transmitter specified by DJI. The iOSD

supports online upgrades. The iOSD has built-in BEC, which is on one hand for the power supply of the camera, on the 

other hand for the power supply of the autopilot system’s main controller to improve the power supply reliability of the 

main controller.

1000mA Battery Pack 

The Fat Shark dog bone shaped 1000mAh pack 

seats securely in the headset strap pocket. The 

battery cable extends out of the top of the pack to 

avoid contact with head strap. Barrel connector cable 

features high strand count wire for flexibility and long 

life. Wire stress is minimized by the additional rubber 

gasket around the cable exit. No special charger is 

needed as balance leads have been added for 

charging with standard RC chargers (battery includes 

discharge lead adapter for advanced chargers). 

Note: this battery can still be charged via the barrel 

connector with the original Fat Shark headset battery 

charger. 

Diopter lens 

For near sighted users, diopter lens insert sets are available that include -2, -4 and 

-6 dpt. See below inserting location. Lens orientation is not critical. 

Adjustable Earphones 

For simplicity and minimalist controls, the AttitudeV2 does not have volume control.

SpiroNET Circular Polarized 

Antenna 

The best performance enhancement for your dollar. 

SpiroNET circular polarized antennae are manufactured to 

machine tolerances and final tested with top end RF 

equipment for the best performing CP antenna on the 

market. 

CP antennae naturally reject multipathing (biggest cause of 

5G8 video breakup) and have no mismatch polarization 

when your aircraft banks – resulting in no rude range losses 

during acrobatic flight. 

Tiny Telemetry From ImmersionRC 

Conventional OSDs offer a host of features, some of which you don’t need 

if you’re just flying FPV around your local field or have a small and light 

FPV plane that can’t really carry a full OSD. All you really want in those 

cases is for your tracking antenna to point at the plane accurately and 

have GPS positional data along with vital statistics such as battery voltage 

and current consumption. 

TinyTelemetry is a minimal GPS locator that sends EzTelemetry data for the 

EzAntennaTracker down one of the audio channels on the audio/video transmitter. 

The EzAntennaTracker will then track the plane and offer battery statistics on its 

LCD display as well as other telemetry data such as positional info etc. 

The new v2.0 EzAntennaTracker will also offer audible warnings for battery voltage 

and total current consumption. 

The Tiny Telemetry plugs into the transmitter’s dongle power supply located on the 

back of the transmitter.

Operational advice  For best performance, select a channel that has the least amount of 

interference. While the transmitter is turned OFF, turn on the video 

headset and look at the screen as you check each channel. Clear 

channels will have a consistent static background. Channels with 

interference will have horizontal static lines. 

 Always perform a range test before flying. This includes AV and RC 

controls. Some RC receivers can be affected by the proximity of other 

electronic devices particularly the AV TX. 

 Try to space out your components as much as possible to avoid 

interference to your RC control range (keep stuff away from RX) 

 Until experienced, practice flying in a familiar area to avoid becoming 

disorientated. 

 Due to antenna characteristics, there is a “null” in line with antenna 

direction. You may experience excessive video breakup when flying 

overhead 

 5.8Ghz signal strength drops off very fast, stay safely within solid AV 

range. 

 For maximum distance it is very important that a clear line of sight exists 

between the transmitter and the video headset. 2 of the worst causes of 

interference are human bodies and reinforced concrete. 

 Place your TX antenna in open area in a vertical orientation 

 Multipathing (reflections off buildings/ tall objects) causes signal 

cancellation and result in broken video. Fly in open areas away from 

buildings or other tall structures (i.e. barns, hills). 

 5.8Ghz AV with 2.4Ghz RC controllers: 2.4Ghz may cause harmonic 

interference on Ch2 – Ch7 of the 5.8Ghz AV (Ch1 not affected). The 

headset has been equipped with a high pass filter that will allow the 

system to work with CE certified 2.4Ghz RC controllers. However, the 

filtering may be insufficient to remove noise from overpowered non CE 

certified controllers. 

If you experience interference from your RC radio, change the AV channel 

to channel 1. 

 Although you don’t require any license to operate this device, you are still 

legally responsible for operating in a responsible manner. 

Warranty 

The system can be exchanged for a new unit within 30 days for any manufacturing 

defects if returned in new condition. The video headset will be warranted for repair 

for 2 years if no signs of excessive use. Buyer will be responsible for shipping 

costs. If beyond the warranty period we will provide repair services.

Introduction

Thank you for purchasing a set of FlightLights, a high performance LED system for model 

aircraft designed and manufactured in the UK by BrainCube Aeromodels. 

This manual will describe how to safely use the various features of the FlightLights 5 controller 

and how to install the controller in a model aircraft. Please ensure you read this manual in full 

before fitting or operating your lighting system.

It is your responsibility to ensure that you operate the FlightLights 5 controller and BrainCube 

LED modules within their stated specifications. Failure to do so could result in permanent damage 

to components, battery packs, property or personal injury. BrainCube Aeromodels Ltd can not be 

held responsible for misuse, intentional or otherwise, of our products. Please ensure you observe the 

following safety points:

• The FlightLights 5 controller can reach temperatures in excess of 80°C under high loads 

(ten light modules or more, total load over 2.5A) and may burn skin or damage heat 

sensitive components.

• BrainCube lighting modules can reach 60-80°C during operation. This is normal, due to 

the very high light output and high current operation.

• Disconnect the LED battery when storing your model to prevent over-discharge.

• Do not stare into the light modules or view through optical instruments whilst on - they 

are intensly bright and may hurt your eyes.

• Always range check your model with the lights running after installation to ensure there is 

no interference.

The FlightLights v5.0 controller is a high performance microprocessor controlled, remotely operated LED driver and light sequencer. It contains an integral high voltage, high current switching 

power regulator and drives four output channels for navigation, landing, upper strobe and lower 

strobe lights.

The controller will convert a wide input voltage range into the 5V supply the LEDs require, and 

can supply up to 4A of current. The LED power supply is isolated from that of the receiver to protect your radio gear from the high current draw of the light modules. All battery types are supported, including Lithium Polymer, with a voltage range of 6 - 42 volts (2-10S LiPo packs).

The controller can learn the transmitter signals you want to use to switch the lights, making it 

easy to integrate with your model (see page 4). There are 10 flash patterns pre-programmed, some of 

which include Rotating Beacon simulation (see page 5).

The controller’s operation is set via the small rotary control dial located on the front top right 

side of the controller. A small, flat-head screwdriver is needed to move the dial. It can turn approximately 3/4s of a turn between the end-stops - be gentle, excess force will damage the dial.

The unit should be fixed in position with double-sided foam tape, self-adhesive Velcro or cable-ties so that it can't move around in flight whilst also minimising the controller’s exposure to vibration. Try and avoid placing the controller or it’s leads too close to your receiver or receiver aerials 

to minimise the risk of interference. Remember to range check your model with the lights running.

It is important to remember that the controller generates heat during operation, proportional 

to the number of lights it is running. Mounting it where cooling air can flow over it is required if 

running more than 10 light modules (2.5A total load).

The light modules should be plugged in with the connector vertical and black wire on top.

The light modules will only work if the polarity is correct, but they will not be damaged if they are 

briefly plugged in backwards. There are three sets of pins for the navigation lights, and one pair for 

each of the strobe channels and landing light channel. 

The six pairs of output pins will also accept normal servo plugs inserted vertically with the black 

(negative) wire on top. If you require more lights than there are sockets, you can use standard servo 

Y-leads, providing you do not exceed the current handling capabilities of the controller.

The controller has three modes of operation, which are described in the following sections. The 

position of the control dial when receiver power is turned on determines which mode the controller 

starts in.

The controller recognises three control dial positions:

Position 1: Anti-clockwise limit

Position 2: Center position – slot horizontal

Position 3: Clockwise limit

Remember not to force the dial - if you feel resistance you have reached an end-stop.

The controller can learn the transmitter signal levels that you want it to switch at, as well as the 

safe cut-off voltage for your chosen power source. The learning procedure is as follows:

Operating Modes

Position 1 - Learning Mode

1. Plug everything in as it will be set-up on the model. Ensure your LED battery is fully 

charged, and is the same one that you will use in the model.

2. With the power OFF, turn the control dial to position 1.

3. Turn on your transmitter and configure the channel you wish to use to control the lights.

4. Set the transmitter channel to the “lights off” position.

5. Turn on LED power followed by receiver power. All the LEDs will flash 5 times to indicate 

you have entered learning mode.

6. The controller will measure the LED battery voltage and remember a safe lower voltage limit 

derived from this (75% of the measured voltage or 3.15V per cell for LiPo batteries).

7. After 6 seconds, the controller will record the “lights off” value and flash all LEDs once.

8. Move the transmitter control to the “nav and strobes on” position. After 3 seconds the controller will record this value and flash all the LEDs twice.

9. Move the transmitter control to the “landing lights on” position. After 3 seconds the controller will record this value and flash all the LEDs three times.

10. All LEDs will then light for a one second long flash to indicate that you have finished.

11. If you are happy with the settings, move the control dial to position 2 and the controller will 

store the settings and move to normal operation. If you are not happy with the settings, remove receiver power without moving the control dial and the new settings will be discarded. 

If you accidentally save incorrect settings, see page 5 to reset to the factory defaults.
5

During normal operation, the controller will switch the navigation, strobes and landing lights 

based on the stored transmitter signal levels. If you haven't gone through the learning mode, these 

will default to values that are compatible with a transmitter channel operating from a three position 

switch, and a 2 cell lithium polymer battery pack.

The controller constantly monitors the voltage level of the LED power source. If this level drops 

below the stored cut-off voltage (by default 6.3V - safe for a 2S LiPo battery), the power supply is 

placed into standby, the LED modules are turned off and the controller’s status LED will flash twice 

a second. The LED battery should be disconnected to prevent over-discharge.

The controller will go into standby mode if it has been powered up for more than thirty minutes (even if the LEDs are turned off) to prevent excessive heat buildup. The status LED will flash 

once every two seconds. Even when the LEDs are off, the power supply draws a small current from 

the LED battery pack - please disconnect when storing your model.

The controller comes with 10 flash patterns programmed, some of which incorporate “rotating 

beacon” functionality – this simulates a light with a rotating mirror that some aircraft use instead of 

a strobe light. To select the flash pattern, turn the control dial to position 1 or position 3 to move 

up and down (respectively) through the flash patterns. Each pattern will run for five seconds before 

moving on to the next so you have time to see what it looks like. If you want to keep the current 

pattern, move the dial to position 2 and the controller will store the setting and resume normal 

operation.

Light Positions

According to the FAA regulations, civil aircraft navigation lights should be positioned thus:

(b) Left and right position lights. Left and right position lights must consist 

of a red and a green light spaced laterally as far apart as practicable and 

installed on the airplane such that, with the airplane in the normal flying position, the red light is on the left side and the green light is on the right side.

(c) Rear position light. The rear position light must be a white light mounted as far aft as practicable on the tail or on each wing tip.

- FAR Part 23 Sec. 23.1385

Note that “left” and “right” refer to the aircraft from the pilots view point, not an external 

observer. The anti-collision strobe lights have the following requirements:

(b) Field of coverage. The system must consist of enough lights to illuminate 

the vital areas around the airplane, considering the physical configuration and 

flight characteristics of the airplane. The field of coverage must extend in each 

direction within at least 75° above and 75° below the horizontal plane of the 

airplane, except that there may be solid angles of obstructed visibility totalling 

not more than 0.5 steradians.

...

(d) Colour. Each anti-collision light must be either aviation red or aviation 

white and must meet the applicable requirements of Sec. 23.1397.

- FAR Part 23 Sec. 23.1401

The strobe lights that are supplied in the standard FlightLights set are red, but the white light 

modules work perfectly well – additional light modules can be purchased individually from the 

BrainCube Aeromodels website – http://www.braincube-aero.com.

Modern military aircraft generally follow the same guidelines. These rules only cover the 

minimum requirements, a lot of aircraft have significantly more lights. Landing lights, taxi lights, 

formation lights, livery illumation lights can all be seen on commercial and military aircraft.

Older aircraft generally had a more relaxed approach to lighting, and there is little consistency – 

Google image search can be a big help getting a scale model lit correctly!

Matters Need Attention

1. The ability of penetrating of radio signal from 2.4GHz wireless data-link is weak; 

please make sure the antenna of it is always visible to the ground end during the flight. 

Human body, trees, buildings or hills will stop the communication between air end and 

ground end.

2. You’d better put the ground end at high place. This can guarantee a good 

communication range.

3. Make sure the antenna head of air end is erect down, and the antenna head of ground 

end is erect up. Make sure there is no obstacle between antennas; otherwise the 

communication range will be reduced.

4. Ground end Link-Alarm red light on is distance alarm, red light off is safe. When it is on, 

you’d better return your aircraft.

5. When ground end Link-Alarm green light is off, this indicates the communication 

between ground end and air end is off, whatever the state of red light.

6. Make sure the driver is installed correctly.

7. Please choose the right com port.

8. Check out the power supply of wireless data-links before use.

9. Please close the DJI assistant software before open the ground station. Otherwise 

there will be port conflict.

10. Make sure the distance between 2.4GHz ground end and air end is over 1.5m; the 

distance between 900MHz ground end and air end is over 5m.

11. Use the right cable for connection.

12. High voltage servos & FBL systems can drain the flight battery fast. Please make sure 

your flight pack is sufficient for the flight time intended.

13. About control modes (Manual, Atti., GPS Atti., GPS Cruise), please refer to ACE 

Control Modes in ACE Waypoint User Manual and WKM Control Modes in WKM User 

Manual.

14. Autopilot Mode (auto mode) means: GPS Atti. or GPS Cruise Mode in ACE; GPS Atti. 

Mode in WKM.

If you have any problem you cannot solve during installation and usage, please contact our 

customer service.

Connection

Antenna Head

Ground End · You should have a DJI Ground Station installed laptop. · Use the USB Cable supplied by us to connect the wireless data- link ground end to you laptop. One end of the USB cable has two heads, make sure the communication interface is plugged into your laptop. If the power supply is insufficient using one USB port, then plug the power interface Into the laptop also.

Air End · 900MHz wireless data-link air end has two CAN ports. When you use it with ACE autopilot system and low voltage servo, you should connect one CAN port to sparE CAN port on autopilot system, and connect another one to a battery whose output voltage is in the range of wireless data-link air end working voltage. · 2.4GHz wireless data-link air end has only one CAN port. · Usually connecting one CAN port on air end to any spare CAN port on DJI autopilot system is enough. · WKM user should use it with PMU. · High voltage servos & FBL systems can drain the flight battery fast. Please make sure your flight pack is sufficient for the flight time intended. · Make sure the antenna head of Wireless data-link air end is erect down, then you can have the largest range.

(2)Altitude Offset Setting

 GIS database (Google EarthTM) is not precise, while Flight Path Mountain and other obstacle/building 

collision checking feature performed based on this database, which is not real-time or up-to-date. 

Google EarthTM plug-in is only for the purpose as a general landscape browser, for quick way points 

positioning without much safety guarantee.

 Pressure sensor is used for altitude sensing, leading the result varies according to weather. Therefore, 

you might have different altitude values on the same location at different times. However, its relative 

height may be far from precise than absolute altitude information in GIS.

 Due to above problems, the following method for relative flight height calculation would be most reliable.

1) Record the aircraft altitude before take-off, as LGound

2) Way point altitude = Relative Flight Height + LGound

Please keep in mind that this method is the most reliable way for flight path collision precaution.

 The Altitude Offset value given is only for the purpose to avoid visual confusion, such as Case 1 in fig.1

shown below. The aircraft represented by the red point was located on the ground in real world but 

floating in the sky within 3D-Map. You have to give a negative offset value to reduce the aircraft altitude 

for visual effect only. The calculate altitude offset function will give you a suggestion for offset setting but 

not guaranteed to be correct. Because if the aircraft is landed on the roof of the building as in Case 2 in 

figure shown below, and the building information will not appear in GIS database, which means you 

cannot use the same method as in Case 1. You should calculate this offset value with a known or 

estimated building height.

Tips:

We highly RECOMMEND you to consider the relative flight height discussed during flight mission editing.

2 Joystick/Keyboard Mode

Joystick/Keyboard mode is the 2nd permission for users, and Fly Simulation, One Key Takeoff and Joystick/ 

Keyboard functions can be operated.

2.1 Simulator

Pre-Flight Simulation aims to help you getting familiar with the Ground Station software. A successful flight 

under simulation mode does not guarantee your aircraft to work successfully in real world, since it is only a 

virtual environment based on the assumption that your aircraft is working under perfect condition with infinity 

power supply, favorable weather, and also that the GIS & GPS are providing 100% correct and precise 

information. The aircraft physical model in simulator might not perform the same flight characteristic as your 

real aircraft.

Notices:

ENSURE the following requirements whenever during/before Simulation Mode: 

1) You MUST NOT take off your aircraft. 

2) You MUST NOT turn on your aircraft engine/motor. 

3) You CAN disconnect the power supply for electric motor, or disconnect the throttle control servo 

motor for fuel engine. Otherwise, incorrect operation could result in serious personal injuries.

Please follow the steps strictly for Simulation Mode use:

1. Connect the whole main control system completely, including IMU、GPS, etc.

2. Hold Ctrl then Right click, you will see simulate, and the aircraft logo will be at the current mouse 

position.

3. Click simulate, you will see a “Warning” window.

4. Click Yes to turn on Simulate Mode. Now GS is in Simulate Mode!!!

Notices:

 We HIGHLY RECOMMEND Simulation Mode for practicing purpose for flight mission edit, try to get 

familiar with all the operations of your Ground Station as much as you can.

 The simulation model requires a complete main control system connection, and you can reference 

to Assembly in DJI autopilot system user manual.

Travel Calibration If the Landing Gear you got has been installed with the servos, please skip this step. Otherwise, calibrate the system using the following procedure. 

1. For safety reasons, please keep your hands away from any link mechanism to avoid injury. 2. Make sure the [R], [L] and [IN] connections are correct and firmly connected. 

3. Hand the Landing Gear in the air during calibration, as the landing gear will move. 4. Keep pressing the SET button using a small tool and power on. You can see the LED flashes YELLOW 

quickly, and then press the SET button once again. The system begins auto calibration with the indication of the LED flashing YELLOW slowly. DO NOT obstruct any moving part during auto 

calibration. 

5. First the left-part is calibrated, the left link mechanism first moves up then moves down automatically. 

Then the right-part is calibrated, the right link mechanism first moves up then moves down automatically.

6. After calibration, both left and right parts are in the [Lower] position, and the LED is on solid GREEN. 

Then the landing gear will work normally. 

Notes:  If the LED is on solid YELLOW when calibrating, then it means that there is something wrong with the 

calibration, please re-do the Servo Installation of the Assembly & Connection section, since the servo arm might be installed with a wrong angle. 

 Please avoid any obstruction when calibrating. If the landing gear is blocked from moving, please 

recalibrate the landing gear by the above steps. 

 If the [R] and [L] servo cables are reversed, the travel will not be measured correctly. Please connect 

correctly and recalibrate the landing gear using the above steps. 

 If the LED flashes slowly GREEN after power on, please re-calibrate the system using the above steps.

R/C Transmitter (TX) Setting 

Select a 2-position switch channel (default setting is OK) on the TX as the control input of the landing gear, and then make sure the corresponding port of the receiver is connected to the [IN] port on the control board. Fig. 1 

Fig. 2 

Tips:  If the switch channel on the TX has fail-safe function, set the fail-safe value to [Lower] position, so that 

the landing gear will be in [Lower] status when the receiver enters fail-safe, to land the aircraft safely.

 To avoid false switch triggering, you can use the slide lever or other trim as the landing gear’s control 

switch.

Before reading this manual please read our TX manual. Several repeated sections are committed from this 

manual and are only explained once in the TX manual.

Technical specifications NR

The receiver board is 26 x 54 mm

Weight: 6.5 gr. without antenna wire - 8.5 gr. With antenna wire.

Sensitivity: -102dBm

Input supply voltage range: 4-10V

Servo signal pulse output: 3.3V positive.

Radio band: 433 & 444Mhz multi band and multi frequency hopping system.

Temperature range: -40C to +70C tested

Receiver 8ch - optimized input filter so it can co-exist with strong 2.4Ghz on board video transmitters.

Wire antenna mounted directly on the Rx.

The extra pin in ch 12 connector is RSSI out. Ch 12 connector is also PPM out when < 12ch are used.

PPM out is the same as sum-signal and this is of course fully compatible with MikroKopter controller board, 

all RX have this SUM and RSSI out.
3

Technical specifications LR

Improved input filter, now even better attenuation for 900 - 1300 - 2400 video transmitters virtually 

impossible to jam. Improved distance of the servo connectors, now all 12 can be mounted at the same time 

and no bending or problems.

The receiver have the following dimensions:

Width 34 mm. 

Length 62 mm. including angled connector

Height 10 mm.

Weight: 16 gr.

Double LNA Low Noise Amplifier frontend with fast signal switch for the best signal.

Two MCX connector coax dipole wire antennas come with each RX t - Weight 5.4 grams each.

The extra pin in ch 12 connector is RSSI out. It’s now buffered so loading of the RSSI out is uncritical, 1k 

ohm Zout, It is also filtered to avoid less jumpy OSD readings.

CH 12 connector is also PPM out when < 12ch are used (auto mode is the default).

PPM out is the same as sum-signal and this is of course fully compatible with MikroKopter controller board 

and all RX types and models have this.

Sensitivity: -113dBm to -114dBm

Input supply voltage range: 4-6V (rx uses 134mA at 5V)

Servo signal pulse output: 3.3V positive

Radio band: 433 & 444Mhz multi band and multi frequency hopping system.

Temperature range: -40C to +70C tested

Binding

The binding function stores the TX signal unique ID code and PPM frame rate and number of servos into the 

receiver; this must be done every time the number of servos is changed on the RC unit. (or another RC 

system is used with this system). The binding procedure is explained in the TX manual.

Failsafe preface

The push button on the top of the TX is used both for binding and to store Failsafe into the receiver.

When the button is pressed, while the TX is powered on the unit is binding. When the TX is in normal flight 

mode, the button is used to store failsafe.

The different modes of failsafe in the receiver manual are:

 The “Normal”

 The “Sequential”

 The “None”

All kinds of FAILSAFE storing and testing should be carefully performed with the plane firmly grounded.

It’s normally good use full failsafe style to program the plane to shut off the motor and turn slowly to the 

left side. Some FPV/UAV systems can use other settings; the user should know what is best for his usage.

Always test if it’s working as expected before a flight – Test if recall the wanted function and recover again 

when the TX is powered back on.

The 3 Failsafe in detail

Link to binding guide on YouTube: http://www.youtube.com/watch?v=9BO-uwYcfys

The normal kind of failsafe is one set of servo positions stored in the receiver. This setting will be recalled 

and used when the radio signal is lost for about 1 second. To store a set of servo positions, push and hold 

the button for 1 second and then release it. Please be sure not to push it again the next 5 seconds.

The “Sequential” works almost the same way. The difference is that you push the button again under 5 sec 

and then release to store the next set of servo positions. This can be repeated 3 times to use all 3 servo 
5

memories. They are recalled in same order as stored and when/if the radio signal is recovered the return to 

normal flight is the reverse way. 

The procedure is as followed:

The radio signal is lost - recall 1, recall 2, recall 3.

Radio signal is back, - recall 2, recall 1, live.

It will run scan mode which means, if a good package is received while it is in recall 2 state, it will go directly 

to recall 1 and then back live. Each recall state takes about 0.3 seconds then it recall the next state. This 

special kind of failsafe can be used to handle special features on some multi rotor flight controller boards to 

activate the RTH or safe landing procedures, depending on how you moved your switches while you stored 

the fail safes.

The “None” is when the receiver doesn’t have any positions stored at all. In this way nothing will be 

recalled and it will simply hold last known good position of all servos. To clear the failsafe memory, hold the 

button for 5 sec.

A little side note on failsafe storing. The Receiver will loose radio link and recall failsafe settings, while you 

activate a storing. The reason for this is the kind of memory used for this is a bit slow and while the CPU 

waits for the saving it’s not able to maintain a perfect hoping sequence. This is perfectly normal but it is not 

normally seen when you only store one set of positions, since the values you recall while you hit save are 

mostly the same as your active positions.

Ch12/PPM options

The signal CH12/PPM - If you use under 12ch you will always get PPM out of the ch12 connector. However 

if you need PPM out and use 12 channels then you simply configure it to be in PPM OUT (See special 

features configurations for guidelines how to do this).
6

RSSI output

Link to guide on YouTube: http://www.youtube.com/watch?v=Xo0Mu1N-okI

The little extra PAD over the CH12 connector is the RSSI output. This is an analog voltage that reveals how 

strong the signal is from the TX. Many OSD types can use this voltage to display a calibrated 0-100% 

readout on the screen display. The minimum and maximum voltages are a little bit different from RX to RX, 

so you must perform a new calibration if you swap a receiver in your system.

Connectors Servo

Look carefully at the connector pins and the PCB. The edge rows are all GROUND, the centre row are +5V 

and all top pins are the servo channels out.

Serial Debug Output

The upgrade connector pin out

1 = GROUND (2, 3, 6 are not connected)

4 = Radio data (do not connect anything to this pin in flight mode)

5 = Debug data output

The debug out is a 3.3V serial signal, can be used for OSD or onboard flight recorders,

The data format is very simple, 9600 Baud 8N1.

The data you will get are:

G: number of Good data packages received
7

B: number of Bad data packages received

F: number of Failsafe recalled

Values are counted from RX power up and will be zeroed again at next power up, so it is possible to land, 

connect to a PC via serial port converter and see the values for the flight, before you power off the RX.

The serial debug can also be use full to test failsafe storing and recalling, it writes in clear text what it is 

doing. And it is also active during power up and under special mode setting configurations.
8

Special Features Configurations

Link to binding guide on YouTube: http://www.youtube.com/watch?v=3LkoTTGNRUg

The receiver can be configured to do a few things other than normal.

How to configure (if you don’t need to configure, just power it up as normal)

POWER OFF

Connect a 2.54mm 2 pin jumper (a short circuit connection)

On servo channel 6-7 (YES between the two signals, they are now shorted together)

Power up the RX

See LED D1 is lit, this one is closest to same side as ch6

Now you stored a permanent setting: PPM out even if you use 12channels.

Power off, remove jumper, connect your servoes, test all works.

POWER OFF

Connect a 2.54mm 2 pin jumper (a short circuit connection)

On servo channel 7-8 (YES between the two signals, they are now shorted together)

Power up the RX

See LED D2 is lit, this one is closest to same side as ch8

Now you stored a permanent setting: servo ch 12 out, if you use 12channels.

Power off, remove jumper, connect your servoes, test all works.
9

If you use under 12ch, you will of course always get PPM out of the ch12 connector, after a setting change, 

or PPM timing change or number of channels assigned, you must always perform a bind and store failsafe

and test all settings works.

Antenna Setup

The ground wire must be separated a bit from the coax. There are no rules of how much of a 

distance, but 3-5 cm is normally used.
10

RX antennas always have to mount with a 90 degree from each other. With this setup there will be no lostspots. See this example with an airplane.

- The antennas are the red lines.
11

Also some general rules.

Mount all types of receivers as far away from transmitters and cameras.

All types of metal, carbon, wires, electronics, must be kept away from antennas

and its ground wires, too close located wires can "short-circuit" an antennas function.

Do not lay down the V flat horizontally, like on a delta wing. This will be the most easy thing to do,

but it is the worst result possible for long range, since the TX antenna is normally pointed up, vertically.
12

Firmware upgrading

Use the 6 pin female connector it is clearly marked with UPGRADE or FIRMWARE UPGRADE, note the arrow 

to pin 1 and also the upgrade text is located closest to pin 1. Actually any USB interface with FTDI232 

chipset can be used - the Arduino bootloader type or our own called TSLRS-USB. They both fit directly into 

this 6 pin row.

First install FTDI virtual com port driver

http://www.ftdichip.com/Drivers/VCP.htm

Then download mcuboot original version (some users might find version 1.3 works better if win7 or win8)

http://webx.dk/rc/uhf-link3/mcuboot.e_x_e

If this version doesn’t work with your version operating system, please try this mcuboot version 1.3 

http://webx.dk/rc/uhf-link3/mcuboot13.e_x_e

Rename e_x_e extension to exe, this mcuboot.exe is made using Borland some PC's might need some DLL 

files, in that case you will be notified about their names, if so, ask support or search for them on the 

internet.

Select right comport - check your virtual comport number is right if you use USB, click OK
13

Browse to the HEX file you got via email, using OPEN.

Remember the TX hex is for TX unit, and the RX hex is for the RX.

File is accepted and loaded, pull down the window so you can see the black status area, click CONNECT
14

Mcuboot now instruct you to cycle powersupply it means actually you POWER UP RX or TX unit NOW

Now you should be connected to the "secret" bootloader program
15

Click Program and look on the screen and status area checksum bytes.

After 7 sec your unit is upgraded. The Bootloader will exit and mcuboot will say Programming done, now 

check that firmware is working and new features work as expected. You MUST read about the features of 

your new software so you know how to use it. You must expect to perform new bind and new store failsafe 

after an upgrade.

Option Board for RX LR 7.01

The option board contains a data modulator, so live flight data from the OSD is modulated into audio that is 

then transferred to ground station via the video links audio channel. This option board is ONLY compatible 

with RX LR 7.01 and up.

THIS SECTION WILL BE UPDATED WHEN THE OPTION BOARD IS RELEASED.
16

LED indicators

The NR has got one LED it simply indicates valid supply voltage.

The LR has got two LED’s one located near each antenna connector.

The normal operation of the LED’s are during flight and installation to show what antenna signal is the 

strongest, since that is the selected signal. 

FAST Blinking LED during power up indicates search mode.

FAST Blinking LED during flight, indicates failsafe is recalled and search mode is now running.

Technical specifications

RF Output power : 500mW/1000mW/2000mW 

RF Output connector BNC female.

The power of the transmitter is user selectable via easy to access 3 way switch.

(We recommend to use as little as possible power, so power up is possible in case an out of range situation is experienced)

The Transmitter can handle full power, continually no time limit.

The Antenna output is designed for 50 Ohm load; however the transmitter stage is specially protected and 

can handle full power at both open and shorted antenna.

It is normal to perform range check with antenna removed and 500mW setting.

The PPM input signal can be either constant frame repeat time or variable, Positive or Negative 

polarisation, the special double speed Futaba PPM signal is also accepted, Auto detects and auto handle. 

The Main PPM signal must contain from 4-12 servo channels, if main PPM signal has under 4 ch it will be 

refused. Note Graupner call each way a servo travel for a channel, so in Graupner terms a 24 Channel 

setting handle 12 servoes and is what we call a 12 channel signal.

Stereo Jack for Audio Demodulator input and Headtracker PPM input

The top of the connector is Head-Tracker PPM input (shorted HT)

The Ring of the connector is AUDIO input from the wireless video system receiver.

Ground is common for both signals.

Shielded cables are recommended to avoid cross talk.

Hardware specifications

Supply voltage 5-25V for 500mW power

Supply voltage 6-25V for 500mW-1000mW-2000mW power

Supply power usage is 3 times the transmit power.

Supply current at 20V (500mW x 3 = 1.5W / 20V = 0.075 Ampere)

Supply current at 10V (500mW x 3 = 1.5W / 10V = 0.15 Ampere)

Supply current at 6V (2000mW x 3 = 6W / 6V = 1 Ampere)

Battery life - The TX unit draw about 1.5W as mentioned at 500mW out, to find the current it draws we use 

ohm law. Like in the examples, watt / supply volt = Current, the supply voltage can be anything from 6-25V. 

Example with a 3S lipo: 1.5W / 11V = 0.126A

To find the time you can run with a given battery size, take your battery mAh and divide with current usage 

also in mA. Example: 1000mAh / 126mA = 7.9 hrs, remember to keep a good safe margin, some batteries 

like LIPO do not like to be totally empty.

When using the power-up feature, input supply power will also go up. The unit has about 30-40% 

efficiency, so an easy rule is the input usage is 3 times as much power as the output power. At 2W RF out;

the TX unit consume almost 6W, this means 4W is radiated as heat.
5

The TX unit can deliver 500mW out at only 5V as supply voltage; it will stop working at 3.3V or under.

For 1W and 2W output, you need supply voltage of at least 6V. Maximum is 25V !

Peak operating heat sink temperature -40 C to + 80 C

Suggested Operating heat sink range - 20 C to + 60C

PPM input both, main PPM and HT PPM level 1.5Vpp to 10Vpp

AC or DC coubled, this means it is also JR and Graupner student signal compatible, however for serious 

stable long range flight, it is recommended to use a 3-5V DC coupled PPM signal for best stable signal to 

noise margin.

Physical Dimensions

Height 32mm

Width 74mm

Length 100mm

Legal Information

The radio system is using frequency hopping, random sequence, and very short timeslots, the time per 

channel is only 15mS, this means it apply to the 10mW pr average channel regulation in EU and many other 

areas, this means the 500mW peak setting can be used legally without any radio amateur licence.

receiver; this must be done every time the number of servos is changed on the RC unit. (or another RC 

system is used with this system)

To bind

1. Power off Tx and Rx.

2. Powerup the TX, (we assume right plane memory is recalled on your RC unit).

3. Hold down bind button on TX while connection adapter cable.
7

4. Remove finger from the bind button.

5. Power up receiver, make sure both antennas are connected and within 20 meter distance.

6. Wait 1-2 sec, see the RX LEDs go from lit into fast blink mode.

7. Power off Tx (Rx is still on).

8. Power on Tx (Rx is still on).

9. Test all servo functions on plane works and have ultra fast and smooth response.

10. With TX on, try to power OFF, and ON the rx and prove it lock to the tx very fast after power on.

Instruction video on how to bind and store failsafe - http://www.youtube.com/channel/UCS2wXoorQHQaYmoSLE5_esg

If you use external battery for the LRS TX, then the binding procedure is a little bit different. Leave the RC 

unit on all the time and connected to the LRS TX, the power on/off to the TX as mentioned in the binding 

procedure is only the LRS TX, now it will work, the binding mode is only activated when button is held down 

while power to the LRS TX is applied.

Change unique ID code

Remove the top lit, inside the TX unit you will find a DIP switch with 8 tiny white slide up/down buttons,

note the text ID code next to it. If you need to create a take-over mission, then the two TX units must have 

the same ID code to be accepted by the RX. If you need to fly side by side with a friend, just be sure you use 

different ID code. After ID code change, a new bind must be performed.
9

Output Power selection button

The 3 way transmit power switch is located near the antenna connector on the top. It’s most easy to access 

while in flight. Move the connector close to the antenna connector for low power mode. It is recommend 

to use as little as possible power, so power-up is possible in case an out of range situation is experienced, 

this way it is possible to regain control and fly back home.

Failsafe

The same push button on the top is used both for binding and for storing failsafe into the receiver.

 When the button is pressed while the TX is powered on it’s in the binding process.

 When the TX is in normal flight mode, the button is used to store failsafe.

Read about the failsafe store and different modes of failsafe in the receiver manual.

Compatibility TX-RX

All versions of TSLRS RX units can be binded and work together with any versions of TSLRS TX units,

because the over air signals are kept the same from the very start. The TSLRS system parts is NOT TX-RX 

compatible with any other brands of long range systems, we all use our own radio modulation system.

Compatible RC's

Any Radio Control remote system with PPM output should be able to use, check your manual for student 

out and if it is compatible with PC simulators and other types of RC systems, then you know you got a PPM 

signal and not a special un-compatible digital signal. The PPM signal can be any polarity and also variable 

speed and even the special Futaba double speed mode is supported.
10

Head Tracker

The Head tracker input must be 6 channels PPM. It accepts positive or negative polarization, variable or 

fixed frame rate auto detect and auto handle. Channel 5 and 6 are the two HT (PAN/TILT) signals. They are 

added after the used MAIN-PPM channels. In case the main PPM signal has 12 channels, there are no free 

channels to use. Then the two HT signals will be merged into channel 10 and 11, leaving channel 12 free to 

use for the main PPM. The reason for this is easy to understand, look at the receivers: The channel 12 

connector can be either PPM out or servo channel 12 out, the different output mode is configured on the 

RX. In case you need PPM out and use a HT at the same time, of course you need the HT signals to be on ch 

10-11 where normal servo connectors exist. 

Compatible Headtrackers

The Fat Shark, M.I.G. Tracker, Magnetic Inertial Gyro or any other type with the required signals, see Heat 

Tracker section above.

Option Board

The extra add on board called Option-Board can be installed by the user.

The extra features are:

 Firmware upgrade via USB connector. 

 Both the TX main board and the Option board CPU can be upgraded with this option board.

 Data Demodulator and PC USB interface for UAV systems. (live 2 way data is then possible)

 Voltage monitor with audio alarm.

THIS SECTION WILL BE UPDATED WHEN THE OPTION BOARD IS RELEASED.
11

Modem Setup Option Board

The audio signal is 1200 Baud FSK from a video receiver, the level can be from 200mV to 2000mV 

adjustable from the upgrade board trimmer, adjust trimmer for carrier LED LIT, find the two points where 

the LED is not lit and set it in the middle of that for best margin to both sides. Install FTDI232 VCD driver on 

the PC, run your UAV control software to display live flight parameters.

THIS SECTION WILL BE UPDATED WHEN THE OPTION BOARD IS RELEASED.

How to get best range

Archived range is only the result of the wanted signal to noise ratio. Local noise emitters are the most 

common way to ruin good receiver’s capabilities to pick up weak signals at long range. The system has got a 

transmitter to receiver calculated line of sight range of over 100 km. We know at least one customer who 

actually performed a full flight over 100 km out and back. To be able to get the full possible range this 

system can deliver, you need to be very sure nothing on your plane emit noise in the used frequency band, 

if it does it will affect the range.. This means also it is very easy to detect using range checks.

LED indicator

Constant light = PPM OK, POWER SUPPLY OK

Blinking LED = Power supply ok, but no valid PPM

No Light = No power supply voltage

Range Check

Can be done just like any conventional RC systems, in this case simply unmount the TX antenna, and set it 

to low power, then expect 4-10 meters of range, then check you have same (short) range with motor 

on/off, and with video cams and video transmitters on/off, if no change in the range result, then mount TX 

antenna again and fly. If any unit on your plane affect your range, you are supposed to seek and fix it, if you 

want to take full advantage of the systems capabilities or at least obtain a system with best possible signal 

to noise margin.
12

Known Limitations

Landscape variations and noise pollution in the flight area is known to shorten the range of any wireless 

link. Use at least 1/10 of the distance as height. For example at 3 km distance stay 300 meters up to get full 

range. Standard transmitter with 500mW and the standard quarter wave antenna will give you a 3-5km 

range in normal city area may be much longer in areas with no noise pollution.

LNA - Low Noise Amplifier is used in receivers as the front end stage, they improve the sensitivity and 

therefore also the range

Diversity - is often a double antenna and/or double receiver system with auto switching to the best signal, 

this improves the useable range a lot.

GPS - often we use a GPS receiver on planes to feed speed, position, and height information to OSD 

systems.

voltage and have lower loss.

RC Receiver Battery or Supply, is normally 4 or 5 NIMH cells providing 4.8 or 6V of steady and stable 

supply, such a battery must be able to handle all servo max currents and still provide sufficient stable 

voltage, do not use spring loaded battery cassettes or weak current capable cells like normal alkaline 

types, today more new and fancy battery types like lipo and lion and such can also be used if receiver 

and servoes can handle the different voltage range they provide.

Fading - when the distance and positions and angles of a wireless system is changed, the radio signal will 

also change.

Multipath Fading - a direct signal and a reflected signal hit the receiver antenna with -180 deg phase, 

creating a zero signal level.

Nulling - is the same as Multipath fading.

FHSS - Frequency Hopping Spread Spectrum, a way to send data using many different frequencies, makes a 

system immune to noise and jamming proof.

FPV general trouble shooting guide

Please read this first and try some of this before asking around. 

Any FPV system a car, plane, or helicopter is often a compact system, containing: Transmitters, receivers, 

sensors, high power pulsed electrical, vibrations, microcontroller electronic boards, video camera, switch 

mode supply to be able to combine all this into a tiny lightweight platform is a huge challenge and to make 

all units perform perfectly without interfering each other is often an almost impossible task, even for skilled 

electronic educated persons. 

Here are a few design hints:

Plane size small planes are cheap and easy to transport, but they are not optimum FPV platforms. The 

smaller type the more compromised performance you must expect to get.

Receivers must be located as far away from transmitters as possible, at least a distance that can prove no 

degrade of the receiver system range when the Tx is operating or not.

It is advised to keep receivers away from all electronics in general, speed controllers and switch mode 

supplies are known to be able to jam.

Electric Motor controller a range check must prove no degrade/change when motor is off, halve, full 

power, this also apply for gasoline and methanol engines.

Transmitters for live video or data back telemetry will always have harmonics like 2x 3x and so on. Of their 

wanted frequency the level might be low and under demanded levels, but when located near a receiver 

that may operate on a x2 or x3 frequency it is doomed to fail. Plan your frequency bands to avoid using any 

channel at the exact harmonic of any other system you use.

GPS are often small module receivers, designed to be cheap and just cheap!! That is what we like, but 

cheap comes a problem. They are not designed to be working near transmitters; some cannot handle 

anything not even if it is even GHZ away. So a SAW frontend is a must too and a good high level capable 

frontend is a must too and even then some GPS modules do not like to be located near 900 or 1300MHz 

video transmitters first harmonic of 900MHz is 1800Mhz, a GPS works at 1575MHz its front end system is 

often several hundred MHz wide, even if they have a SAW, so 1300 and 1800 can jam it. A 2.4GHz video 
16

transmitter is harmonic at 4.8GHz, so it is no big problem, it is a known fact that most 2.4Ghz video 

transmitters are most likely better with most GPS units.

Video stripes is often seen when a power supply is not clean or ground / signal wires are shared with 

power or other units on the plane, note if the stripes are constant or change with motors or servos or other 

items moving or operation, try to touch camera or video transmitter, see if any change in the stripes.

Grounding items with analog signals specially video signals are super sensitive to grounding problems. You 

cannot supply a pulsing current on a ground wire to a video connected device, if this ground wire is the 

same for the video signal, it is quite difficult to explain how to split signal ground with power ground. A 

“Star” kind of grounding has a zero current / zero voltage in the centre point.

Power supply cleanness. Try to mount external battery on different items and be sure they are super clean 

and is smart to try to locate a problem.

Switch mode, it is often seen SBEC or other switch mode regulators are designed to be cheap and they 

don’t have no really good filter, extra 100uH coils and 470-1000uF on the input and output might help, 

input is just as important as the output.

Shielding some devices radiate magnetic pulses, specially SBEC and cameras, if they are contained in a 

closed metal case the problem will be less, but weight will go up, iron cases are better for low frequency 

magnetic problems.

Camera some types radiate radio noise, uncased types are the worst. Cased types can also do it, the case is 

maybe painted and therefore not fully shielded, the wires from it works like radiating antennas, ferrite 

torrid and aluminum-foil is a good solution and distance to GPS and other receivers is a good idea tool.

Servos some RC servos types are only designed to be used near receivers, clear enough, but when located 

near a transmitter they can be jammed, moved or stopped or other strange things even periodic problems 

have been seen. Tricks/solutions: Aluminium-foil around the servo, wire turned on ferrite torrid.

Electrical motors are also inside servos and they will also radiate magnetic pulses when they move.

Some systems like video transmitters and cameras and OSD systems do not like to be near this field.
17

Vibrations is a normal problem for receivers and transmitters, their coils and crystals and filters have 

microphone behaviour, packed in foam and they also avoid loud sound

SWR a video transmitter with a badly matched antenna and/or badly grounded will have high frequency 

currents going on its signal and power cables. 

When having range or interference problems, try to isolate the different items, like turn it off or change 

their position dramatically or bypass its function until you find a change in your problem, then you have 

found the noisy item.

Radio Technical stuff

Any wireless radio system contains of a transmitter side antenna and a receiver side antenna.

Both sides must have the same polarization to perform most optimum, the most common polarizations are 

horizontal, vertical, circular left or right.

If a horizontal is “talking” to a vertical, the link loss will have an added extra loss of 26dB

If a circular left is “talking” to a circular right, the link loss will have an added extra loss of 26dB

If a circular left is “talking” to a vertical or horizontal, the link loss will have an added extra loss of 3dB

This is why it is smart to combine a horizontal or vertical often mounted in a plane, with a circular receiver 

on the ground, then the 26dB drop can nearly be avoided.

Pointing a whip style antenna to a plane is the worst thing you can do. Imagine looking into the end of the 

whip, It is almost impossible to see from a distance, radio waves work this way too, makes antenna most 

visible and right polarization.

It is normal that radio links have a 26dB extra margin in its link budget / range calculation so you will not 

loose contact - when one antenna is rotated in an unlucky angle, a diversity system will take full advantage 

of its link budget, so the resulting useable range is almost 10 times as much as a non diversity system, if no 

other parameters are changed.
18

A downlink diversity system also solves one other problem, fading and nulling, the most perfect diversity 

system would have 3 antennas to handle signals from any angle perfect, but the gain from doing this is 

often minimal and cost and complexity is big, a 2 antenna diversity is the most common compromise.

All cellular systems use diversity on the receiver side and brute transmitter power on the tx side to perfect 

the link, a cell side tx is over 26dB more power full over the handset transmitter to obtain an equal quality 

link, also handset side have a cheaper receiver with less sensitivity, we do not have space for a diversity

antenna system on a cell phone.

Wavelength and frequency - a double frequency will have half the wavelength. Long wavelength cannot 

pass through small holes, like take a 27MHz walkie-talkie and try to use it inside two cars, (cars are made of 

metal, and the window holes are much under the wavelength) the useable range is then really bad, now go 

out of the cars and see you will have 10 times the range, at higher frequencies you don’t have the car 

window problem, but air attenuation is higher with higher frequencies, so a longer range is easier to get 

using lower frequencies.

Gain - Adding more antenna gain will only make the beam more narrow, point the antenna right and you 

get more range, point the antenna wrong and you lose signal, any gain over 8-10dB will be hard to point to 

a moving target like a plane, you need a tracker system or a cheap friend that will work for free to point the 

antenna.

An 18dB gain yagi antenna on the receiver side and 500mW 2.4GHz video transmitter with 0dB antenna, 

have a proven LOS of 51km when both polarizations are right.

Range and dB - Improving a systems link budget with 10dB will increase the range by a 3 times factor, 10dB 

power is the same as 10 times the power.

20dB more power gives 6 times the range, 100 times more power, combining more power with more gain 

is often the way to get longer range and also improving receiver side sensitivity is a good way to go.

Bandwidth vs. range - Video transmitters with audio, stereo and mono exist, the video signal is 5MHz wide, 

and the audio is 5KHz wide, A factor 1000 in bandwidth, so in theory the same range will be achieved on 

the audio as the video link with only 1/1000 of the power, that is why those systems have a much lower

power in the audio, often see -20dBc to -30dBc, dBc means dB under the main Carrier -30dBc is the same as 

1/1000.

I. What is Firmware? 

 

According to Wikipedia, firmware is the combination of persistent 

memory and program code and data stored in it. 

 

Generally speaking, it can be considered to be a built-in program 

and command in electronic products. After MCU powered up, 

firmware will control MCU process signal. It is the soul of the hardware. 

As the factory will download firmware to MCU Flash memory, many

people call this process Flash. 

 

In RC model industry, such products need to flash firmware, as 

ESC, receiver, digital servo, battery charger, etc. 

 

II. What is Simon K Firmware? 

 

According to Google, Simon K firmware is a series of ESC firmware 

developed by Simon Kirby. This firmware has the advantage of 

rapid response, easy handling and good compatibility, which 

greatly enhances multirotor performance. 

 

Simon K firmware is continuously optimized and upgraded since its 

birth. At the beginning, only ESCs with an ATMEL micro controller 

can be upgraded. Now, it can also support SiLabs and Intel 8051

MCU. Besides, the firmware codes are open. You can modify the 

codes yourself. 

 

III. Why do I need to flash Simon K firmware? 

 

A). Continuous exploration. This is the common interest of RC 

model enthusiasts. If you want to know about the principles and

hardware structure of the ESC, you can start by flashing Simon K 

firmware, which will allow you to learn the MCU download process. 

B). Pursuit of changes. When you are tired of one ESC 

“personality”, you can update it by flashing Simon K firmware. 

C). When troubles come out. When your ESC cannot power up 

your new motors, but your companions’ can. You need to 

implement Simon K firmware to your ESC. Simon K firmware has 

excellent compatibility. It can start almost every motor, except for 

damaged ones. 

 

D). New reasons you can find... 

 

IV. How to flash Simon K firmware? 

 

Maybe you once downloaded firmware to the microcontroller in 

your college laboratory. But that does not mean you can flash 

Simon K firmware into ESC’s MCU. 

 

First, pls ensure that your ESC support Simon K firmware. 

Second, pls meet following requirements. 

A). Hex or Bin file 

The firmware for the ESCs is available in a .hex or .bin file. One file 

contains the complete firmware for one ESC. 

 

B). Interface Software (eg. AVR Studio) 

Depending on your platform you will need dedicated interface 

software installed on your computer to flash your ESC with the new 

firmware. 

C). MCU programmer (eg. JTAG or USB ASP) 

 

D). PIN-header or micro-clips to connect programmer to MCU 

Then you can flash the ESC with the video and other information on 

internet. 

 

Note: You can flash your ESC multiple times but only the last 

flashed firmware is active on the micro controller. If the wrong 

firmware is flashed, you may end up with a damaged ESC when it's 

powered by the battery supply. It's important to safely test your 

ESC after the firmware upgrade. 

V. How to get Pre-flashed ESCs with Simon K firmware? 

Flashing your own ESCs is not so easy as you download music to 

your iPhones. It takes time, a flash tool and some research. 

For modelers who do not have any knowledge about MCU, the 

flashing process is difficult. Or some model flyers just need their 

models fly well and do not care about flashes. If you are in one of 

them, you can choose MAYTECH to flash them for you. Without 

any extra cost or time, you can enjoy the excellent performance of 

Simon K firmware. 

VI. MAYTECHTM ESCs VS. Simon K firmware ESC 

 

MAYTECHTM ESCs usually come with MAYTECHTM firmware. This 

firmware has more functions than Simon K firmware, such as 

Helicopter governor mode, set Batt. type, set Brake type, Timing 

mode, Low-voltage protection, etc. 

 

If you need ESCs specially for multirotor application, as many 

functions are realized by the flight controllers. You only need a high 

quality ESC. Your best choice is Simon K firmware ESC. 

 

All MAYTECH TM ESCs (Harrier-Suprem TM \ Harrier-eXtrem TM \ 

Harrier-EconomicalTM\ Falcon-ProTM Series, etc.) can be flashed to 

Simon K firmware, and the Harrier-SupremTM 8A to 85A ESCs are 

recommended. But If you like us flash Simon K firmware to other

series ESCs, pls contact us, we are very glad to do it for you.

MAYTECHTM Eagle-MultiTM (Abbr.MTMK) series ESCs are flashed 

to Simon K firmware on the basis of MAYTECHTMHarrier-SupremTM 

series ESCs. 

VII. Install your ESCs 

 

We believe it is easy for you to install ESCs to multi-rotor platform. 

We still kindly remind you to make sure the correct and solid 

connection of each connector to silicon wire, battery wire to power 

distribution board, power distribution board to ESC, ESC to motor. 

Pls refer to the pic below: 

VIII Simon K firmware ESC start-up tones 

 

All ESCs make the motors sing, so does Simon K firmware ESC. 

When connected to power, you need firstly unlock the flight 

controller. Then ESCs make 3 beeps (di da di), to tell you 

self-detection finished. If flight controller also makes control 

instructions, a long beep (di----) will tell you ESCs have received 

throttle signal from flight controller and ready to start. Then pull up 

the throttle stick, motor starts to run. OK! Let's go! 

IX. How to do throttle calibration 

 

Normally, you do not need to do throttle calibration for new 

multicopter ESCs. However, in some special cases, you still need 

to do it. Remove your props, and disconnect the battery. Push your 

radio throttle to maximum, connect the flight battery, wait for the 3 

beeps(di da di), wait for 1s, you will hear a short beep(di). Then

immediately lower the throttle to minimum. You will then hear 

another unique 2 beeps (di di), indicating you are setting the low 

value. If you hear a long beep, it means the low throttle set. 

Disconnect the battery, throttle calibration is done. If you hear a 

short beep, it means low throttle set failed. You need to do the 

calibration again. If still no success, pls contact us. 

X. Simon K ESC breakdown 

 

Simon K firmware ESC has big starting-up torque, if your flight

controller algorithm is not reasonable or motor quality is not high, 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

too much throttle increment will cause burst current too high to burn 

ESC. We all do not want it happen. To avoid it, we give you the 

following suggestions: 

 

1), Choose low-heating ESCs for your multikopter. 

2), Choose ESCs continuous current higher than maximum current 

of the motor. 

 

3), Ensure good heat-radiation of the multikopter. 

If your ESC damaged during flight, please contact MAYTECH, we 

will solve the problem for you as soon as possible.
