1. Turbo Pix Introduction
Specially developed by RADILINK team, Turbo Pix keeps the complete PIXHAWK functions but resolves its
Alt-Hold uncontrollability problem at high speed. With the software optimization, Turbo Pix achieves better
vibration damping and diminishes the posture deviation. Combination of Inertial navigation and barometer
decreases airflow influences and ensures better stability even when speed up. With the dimension of
39*39*12mm and the weight of 27g including cables, Turbo Pix lightens the whole weight of the aircraft and
diminishes battery consumption, allowing longer flight time. The 8- channel output fits all models including
fixed-wing/helicopter/car/boat/3-8 copters. Turbo Pix can carry 6 pcs SUI04 ( ultrasonic ranging sensor
transceiver) to realize horizontally and vertically overall obstacle avoidance including
forward/backward/left/right/upward/downward (Alt-Hold). Real-time detective and sensitive to the surrounding
avoids the possible collisions during high speed flight.
Note Turbo Pix V1.1 can ONLY flash firmwares from RadioLink
Mission Planner http://www.radiolink.com.cn/firmware/MissionPlanner/MissionPlanner-latest.exe. But not that
from official Mission Planner.

3.4.2 By Transmitter
1. Connect the Mission Planner before compass calibration with transmitter, select Radio Calibration in the
INITIAL SETUP menu( If this step is already done, no need to recalibrate). Select the corresponding firmware
when connecting the transmitter (eg. If it’s the acrobatic model that you aresetting, firmware of same aircraft
should be chosen in the Model Type of BASIC MENU with throttel phrase reversed set in the transmitter.
Signal output of receiver should be SBUS in BLUE indicator)
2. When calibrating compass with the transmitter, no need to connect Turbo Pix to Mission Planner.
Transmitter can be used directly to calibrate the compass of Turbo Pix.
3. Buzzer need to be installed as the notification when calibrating the compass with the transmitter.
4. Power on the transmitter, the throttle gimbal stick should be at the lowest position.
5. Power on Turbo Pix annd wait until its self-check is complete. The normal notification should be RED
indicator flashes quickly-- buzzer makes DEE sounds -- Red and Green indicators flash quickly--
Red/Green/Blue indicators flash intervally-Red and Green indicators flash quickly, then self-check is done.
6. Toggle the throttle gimbal stick to the top position(max.) and YAW to the rightest and hold these positions
for at least 2s after a D sound is made by the buzzer, then two D sounds after 2-3s, then the buzzer will make
continuous DD sounds like once per second, meaning the compass calibration mode by transmitter is
activated.
7. Then rotate the
aircraft as below pics

Radiolink Electronic Ltd

8. When there are three D sounds made by the buzzer, it means the compass calibration is done with
success. Restart the flight controller and it’s enabled.
Note
1. If calibration fails, there would be two D sounds from the buzzer then continuous DD sounds like once per
second, meaning the flight controller restarts to calibrate. Please repeat the above steps.
2. If it doesn’t succeed after several trials, or you are asked to cancle during the calibration, toggle the throttle
gimbal stick to the top position(max.) and YAW to the rightest and hold these positions for more than 2s to
cancel.
3. If the calibration can’t be made with transmitter, it’s adviced to cancel it and calibrate with the Mission
Planner instead.
3.5 Radio Calibration
This article shows how to perform radio control calibration using Mission Planner.
RC transmitters are used to control vehicle movement and orientation. Copter and Plane minimally control
throttle, pitch, roll and yaw, while on Rover we just control throttle and roll. Each of these control signals are
mapped to transmitter stick/switch(s) and in turn to autopilot channels from the connected receiver.
Calibrating each of the transmitter controls/channels is a straightforward process - simply move each of the
enabled sticks/switches through their full range and record the maximum and minimum positions.
There are two main transmitter configurations:
Mode 1: left stick controls pitch and yaw, the right stick will control throttle and roll.
Mode 2: left stick controls throttle and yaw; the right stick will control pitch and roll.
Copter default channel mappings are:
Channel 1: Roll
Channel 2: Pitch
Channel 3: Throttle
Channel 4: Yaw
Channel 5: Flight modes
Channel 6: (Optional) In flight tuning or camera mount (mapped to transmitter tuning knob)
Unused channels can be mapped to control additional peripherals.
For safety, you should disconnect the battery and/or remove propellers before preforming radio calibration.

Bind your transmitter and receiver before calibrate radio, connect Turbo Pix to computer via USB cable
and then turn on transmitter. The RC receiver ask to connect to the RC port of Turbo Pix.
The transmitter will make AT9S as an example in this manual.
1. Press Mode button about one second to into BASIC MENU, and then turn the dial to set MODE TYPE
as MULTIROTOR (press Push button 1 second—press Push button again when the display pop-ups “Are
you sure?”— you will find out DDD sounds come out with “Please wait…”), the mode type MULTIROTOR
have setup success after the DDD sounds have finished.
3. Setup CH3: THRO REV in REVERSE menu (setting steps: Press Mode button about one second to
into BASIC MENU, and then turn the dial to choose REVERSE, press Push button to into the REVERSE
menu, turn the dial to setup 3: THRO REV, press End to back to Basic menu.
