Main function
- 2CH transmitter, It can adjust steering(CH1/ST) TRIM, DR, REV, EPA. Can adjust throttle(CH2/TH) DR, EPA.
- Low battery voltage alarm.
Warning
Please strictly follow the supply voltage mentioned in the manual. Excessive
supply voltage may cause the equipment to burn.
Transmitter battery is suitable for 4 alkaline batteries, ensure that the
positive and negative batteries are installed correctly, incorrect battery
polarity will cause damage to the transmitter! The transmitter uses a red LED
to indicate the battery power. When the red LED blinks from steady on to slow,
it means the battery power is low. Please replace the battery in time!
Transmitter
Install battery
Transmitter battery is suitable for 4pcs 1.5V AA alkaline batteries, Install the battery according to the mark in the battery box.
- Press the battery cover hook in the direction of the arrow, and open the battery cover downward;
- According to the mark in the battery box, put four AA batteries in turn. Do not put the wrong polarity, and do not mix old and new batteries. Do not mix batteries of different specifications.
- Close the battery cover upward and close the hook.
ST
Transmitter can control steering (ST/CH1). You can rotate the
clockwise/anticlockwise ST steering wheel to right /left to control car
steering.
TH
Transmitter can control the throttle (TH/CH2). You can pull the throttle
trigger to backward to control the car forward or push the throttle trigger
forward to control the car backward.
ST DR(SR)
Transmitter can adjust steering (ST/CH1) travel. You can rotate the
clockwise ST DR rotary knob to add steering (ST/CH1) to MAX travel, also you
can rotate the anticlockwise ST DR rotary knob to reduce steering (ST/CH1) to
Min travel, the range is 20%-100%.
TH FORWARD D/R(TH/LIM)
Transmitter can adjust throttle forward (TH/CH2+) travel. You can select
the TH limit switch position to select TH/CH2+ travel. From right to left,3
position can select 50%, 75%, 100%.it can limit throttle forward travel.
This limited switch can not influence throttle backward travel.
ST TRIM(ST)
Transmitter can adjust steering (ST/CH1) middle position. This function can
adjust the servo middle position to let the car run straight. You can rotate
the clockwise/ anticlockwise ST trim rotary knob to adjust the steering
(ST/CH1) middle position to let the car run straight. The default position is
in the center.
ST REV(ST-R)
Transmitter can adjust steering (ST/CH1) turning direction. This function can
adjust servo turning direction to suit different user custom. You can push REV
switch to left/right to reverse turning direction. The default position is in
right.
Low battery alarm
Transmitter has a low battery alarm.
When the battery voltage is lower than 4.5V, the transmitter red LED will
flash slowly.
When the battery voltage is lower than 3.8V, the transmitter red LED will off.
EPA setting
The transmitter can adjust the steering (ST/CH1) left/right travel endpoint.
also can adjust throttle (TH/CH2) forward/backward travel endpoint.
The setting is as follow:
-
Step1.turn the steering wheel to the max right position and push the throttle trigger to max forward position, Hold them and push the power button to open the transmitter.
-
Step2.transmitter red LED will flash rapidly, It means transmitter enter EPA setting state, release steering wheel and throttle trigger to nature position (middle position).
-
Step3.turn the steering wheel to max left position and hold, rotate SR rotary knob clockwise/anticlockwise to add/reduce steering left endpoint.
-
Step4.release steering wheel to nature position (middle position), turn SR clockwise to max position.
-
Step5.turn steering wheel to max right position and hold, rotate SR rotary knob clockwise/anticlockwise to add/reduce steering right endpoint.
-
Step6. release steering wheel to nature position (middle position).
If you only want to adjust steering EPA, you can power off the transmitter, turn the SR rotary knob clockwise to the max position. ST EPA will set OK.
If you also want to adjust throttle EPA, go on step 7. -
Step7.Make sure the throttle limit switch is 100% position.
-
Step8.pull trigger to backward max position and holding, rotate SR rotary knob clockwise/anticlockwise to add/reduce throttle forward endpoint.
-
Step9.release throttle trigger to nature position (middle position), turn SR clockwise to max position.
-
Step10.push trigger to forward max position and holding, rotate SR rotary knob clockwise/anticlockwise to add/reduce throttle backward endpoint.
-
Step11.release throttle trigger to nature position (middle position),.
-
Step12. power of the transmitter.
-
Step13. turn SR clockwise to max position.
Restore factory parameters
If you want to restore the factory setting, all of the parameters will restore the factory setting. (include EPA). The step is as follow:
- Step1.turn the steering wheel to max left position and push the throttle trigger to max forward position, Hold them and push the power button to open transmitter.
- Step2.transmitter red LED will flash rapidly 4 times, It means transmitter restore factory setting.
- Step3.release the steering wheel and throttle trigger to nature position (middle position). transmitter red LED will light. restore factory setting is succed.
Calibration function
Note: Before the transmitter leaves the factory, the throttle and
steering neutral point and the max travel have been calibrated OK.
Incorrect throttle calibration will cause the motor to be unable to output the
full-throttle travel or the throttle backward is not linear; Incorrect
steering calibration may result in the steering servo not being able to output
at full Angle or not being linear at the back of the steering. At this point,
you need to do a calibration of the throttle and steering. The calibration
method is as follows:
- Step1.turn steering wheel to max right position and pull throttle trigger to max backward position, Hold them and push power button to open transmitter.
- Step2.transmitter red LED will flash slowly, It means transmitter enter calibration state, release steering wheel and throttle trigger to nature position (middle position).
- Step3.turn the steering wheel to the max left position and release the steering wheel to the natural position (middle position),.turn the steering wheel to the max right position and release the steering wheel to nature position (middle position).
- Step4.pull trigger to backward max position and release throttle trigger to nature position (middle position).push trigger to forward max position and release throttle trigger to nature position (middle position).
- Step5.hold steering wheel to nature position (middle position) and throttle trigger to nature position (middle position), push ST REV switch (ST-R) left to right and right to left twice to confirm the calibration, the red LED will light to indicate the calibration is succeeded.
If calibration is failed, the red LED will flash rapidly, you need to repeat step1-5 again to re-calibration.
