steps:
1. Turn and hold the wheel as far clockwise as it will turn, hold the throttle all the way forward, then turn on the
transmitter in calibration mode.
• The R.LED and G.LED will be in a state of two-time 󽗊ashing and on o󽗈.
2. Calibrate wheel: Turn the wheel completely clockwise, then completely counterclockwise.
• When calibration is completed the R.LED will be o󽗈.
3. Trigger calibration: Pull the trigger back then forward as far as it will go.
• When calibration is completed the G.LED will be o󽗈.
4. Once calibration is complete press the bind to save and exit.

5.SystemFunctions
This section focuses on the functions and how to use them.
5.1ChannelDescription
5.2ChannelReverse
The transmitter outputs a total of 4 channels, which are allocated as follows:
• CH1：Steering Wheel
• CH2：Throttle Trigger
• CH3：Three-position Switch
• CH4：Reset Button
Note: By default the output of CH4 is 1000us, after which pressing the button will toggle between 1000 and
2000us.
5.3Trims
This function is used to adjust each channels direction of movement in relation to its input.
The ST.REV / TH.REV switches are the reverse buttons for CH1 and CH2. If the switch is up it indicates reverse, and
the down indicates normal.
The ST.TRIM is the trims for CH1 (steering),and can be multiplexed as trims of CH3 and CH4. For multiplexing
switching mode, refer to [5.5 Mode Switching].
TH.TRIMis the trims for CH2(throttle).
Adjustment range: -120us- + 120us, each step is 4us;
ST.TRIM + / TH.TRIM +: Increases adjustment step;
ST.TRIM- / TH.TRIM-: Decreases adjustment step.
LED Indicator:
• When using the trim keys the G.LED will 󽗊ash slowly on short presses and quickly on long presses.
• When the trim adjustment value is at the netrual position, the G.LED will 󽗊ash twice slowly.
• When the trim adjustment value is at both ends (+ 120us / -120us), the trim adjustment is at its maximum and
as such G.LED will not 󽗊ash(If the 󽗉ne adjustment value has been adjusted to + 120us, then press ST.TRIM + /
TH.TRIM + key is invalid and G.LED has no indications.)

9
5.4D/R
ST.D / R is for servo travel adjustment, which can be multiplexed as CH2 (throttle), CH3, CH4 servo travel
adjustment, refer to [5.5 Mode Switch] for multiplex switching mode;
Adjustment range: 0-120%(the default is 100%), the step is 5%.
ST.D / R +: Increases servo travel.
ST.D / R -: Decreases servo travel.
LED Indicator:
• When using the trim keys the G.LED will 󽗊ash slowly on short presses and quickly on long presses.
• When the ratio value is at both ends (0/120%), the ST.D / R button is at its maximum and as such G.LED
will not 󽗊ash(if the ratio value has been adjusted to 120%, then press ST.D/R+ key is invalid and G.LED has
Instructions)
5.5Modeswitching
This function is for reusing the ST.TRIM and ST.D / R buttons for di󽗈erent channels (Refer to [5.3 Trims] and [5.4 D/R).
Function settings:
Under normal power-on, quickly press the Bind button twice (within 1 second) to cycle through modes 1, 2, 3, and
4. The default setting when powering on is mode 1.
Mode 1: G.LED 󽗊ashes slowly once, ST.TRIM is CH1 trim adjustment, ST.D / R is servo travel adjustment.
Mode 2: G.LED 󽗊ashes twice slowly, ST.TRIM is CH1 trim adjustment, ST.D / R is CH2 servo travel adjustment.
Mode 3: G.LED 󽗊ashes three times slowly, ST.TRIM is CH3 trim adjustment, ST.D / R is CH3 servo travel adjustment.
Mode 4: G.LED 󽗊ashes slowly four times, ST.TRIM is CH4 trim adjustment, ST.D / R is CH4 servo travel adjustment.
This function dictates what the receiver will do in the event that it loses signal from the transmitter, this includes
servo position etc.
Function settings:
1. Turn on the transmitter and make sure it is connected to the receiver.
2. Hold the control surface at the desired failsafe position.
3. Press and hold the bind button for 3 seconds, if the G.LED starts 󽗊ashes for 2 seconds, indicating that the
settings are successful.
Note: The fail-safe function has not set at the factory by default. If no failsafe setting has been set, then the
receiver will maintain the output of the last signal when the signal is lost.

5.7BeginnerMode
Beginner mode is designed for the people who is new to the hobby.
In this mode the throttle has been limited to 50 percent, The channel range defaults has been set to
1250~1500~1750us.
Function settings:
To switch between beginner and normal modes, press and hold the CH4 button while turning the steering wheel
completely counterclockwise as far as it can, and at the same time, power on the transmitter.
Note: By default, the system is set to normal mode. If the system has set to beginner mode.
The G.LED will be in a state of two-time 󽗊ashing and on o󽗈, and keep the state for 3 seconds during power on.
