Transmitter battery is suitable for 4 alkaline batteries, ensure that the
positive and negative batteries are installed correct, incorrect battery polarity
will cause damage to the transmitter! The transmitter uses 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.
1. Press the battery cover hook in the direction of the arrow, and open the
battery cover downward;
2. 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.
3. Close the battery cover upward and close the hook.
ST
Transmitter can control steering (ST/CH1). You can rotate clockwise/
anticlockwise ST steering wheel to right /left to control car steering.

TH
Transmitter can control throttle (TH/CH2). You can pull throttle trigger to
backward to control car forward or push throttle trigger to forward to control car
backward.
ST DR(SR)
Transmitter can adjust steering (ST/CH1) travel. You can rotate clockwise
ST DR rotary knob to add steering (ST/CH1) to MAX travel, also you can rotate
anticlockwise ST DR rotary knob to reduce steering (ST/CH1) to Min travel,
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 limited 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 servo middle position to let car run straight. You can rotate
clockwise/ anticlockwise ST trim rotary knob to adjust steering (ST/CH1)
middle position to let car run straight. The default position is in 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 low battery alarm.
When battery voltage is lower than 4.5V, transmitter red LED will flash slowly.
When battery voltage is lower than 3.8V, transmitter red LED will off.
EPA setting
The transmitter can adjust steering (ST/CH1) left/right travel endpoint. also
can adjust throttle (TH/CH2) forward/backward travel endpoint.

The setting is as follow:
. Step1.turn steering wheel to max right position and push throttle trigger to
max forward position, Hold them and push power button to open 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 steering wheel to max left position and holding, 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 holding, 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
SR rotary knob clockwise to max position. ST EPA will set OK.
If you also want to adjust throttle EPA, go on step 7.
. Step7.Make sure 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 off transmitter.
. Step13. turn SR clockwise to max position.
.Restore factory parameters
If you want to restore factory setting, all of parameters will restore factory
setting.(include EPA).The step as follow:
. Step1.turn steering wheel to max left position and push throttle trigger to max
forward position, Hold them and push power button to open transmitter.
. Step2.transmitter red LED will flash rapidly 4 times, It means transmitter
restore factory setting.
. Step3.release steering wheel and throttle trigger to nature position (middle
position). transmitter red LED will light. restore factory setting is succed.
.Calibration fuction

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 steering wheel to max left position and release steering wheel to
nature position (middle position),.turn steering wheel to max right position and
release 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 succeed.
If calibration is fail, red LED will flash rapidly, you need to repeat step1-5 again
to re-calibration.
