ABOUT THE RADIO SYSTEM
Reversing
Reversing is used to change the response direction of steering wheel and throttle
trigger.
KT2S+ Transmitter features 2 reversing functions: Steering Reverse and Throttle
Reverse.
Steering Reverse: Reverse the response direction when operating steering wheel.
Turning left steering wheel, the model turns right while turning right the model
turns left.
Throttle Reverse: Reverse the response direction when operating throttle trigger.
Pushing forward throttle trigger the model moves backward while pulling back,
the model moves forward.
Adjustable Steering Rate (ATV)
Adjustable Steering Rate enables to adjust the same maximum steering angle of servo on both sides (Left and Right) when model makes steering. The
Adjustable Steering Rate affects the sensitivity of servo. Reducing dual rate value can lower the sensitivity of servo and reduce the same maximum steering
angle on both sides. Remember to adjust the dual rate value within the adjustment range: rotate clockwise = increase maximum steering angle; rotate
counterclockwise = reduce maximum steering angle.
The minimum adjustment of ATV (counterclockwise to the max) makes a zero steering angle.
PROGRAMMING THE END-POINTS
In order to avoid mechanical strain when steering to the maximum and/or accelerating and braking (nitro), an EPA function (End Point Adjusment) can be
digitally set. However ATV function can be used for steering end points, but on the left & right together.
If you really want to use EPA function, please read the following instructions carefully:
1. Steering servo
a) Transmitter and receiver powered on (green LED on), turn the steering wheel to the maximum (on the side you want to set), then hold down for 2 seconds
the «BIND/EPA» button: LED turns solid red.
b) As long as LED is red, you can set the exact maximum turning angle of the wheels on the side you choose.
Once the angle is chosen, hold down again for 2 seconds the «BIND/EPA» button. LED flashes twice (light green/dark green) then turns solid green.
IMPORTANT: Switch OFF and ON the transmitter to confirm the adjustment.
c) To reset the default value, follow a) step, then b) step, hold the steering wheel to the maximum and hold down for 2 seconds the «BIND/EPA» button. LED
flashes twice (light green/dark green) then turns solid green. IMPORTANT: Switch OFF and ON the transmitter to confirm the adjustment.
To set the opposite side, follow a) and b) steps in the opposite side.
It is very important to perform these operations one by one.
2. Throttle servo (EPA is recommended only for nitro vehicles)
a) Transmitter and receiver powered on (green LED on), hold the throttle at forward-most position, then hold down for 2 seconds the «BIND/EPA» button:
LED turns solid red.
b) As long as LED is red, you can set the exact your max throttle end-point.
Once the end-point is chosen, hold down again for 2 seconds the «BIND/EPA» button. LED flashes twice (light green/dark green) then turns solid green.
IMPORTANT: Switch OFF and ON the transmitter to confirm the adjustment.
c) To reset the default value, follow a) step, then in b) step, hold the throttle at forward-most position, then hold down for 2 seconds the «BIND/EPA». LED
flashes twice (light green/dark green) then turns solid green.
IMPORTANT: Switch OFF and ON the transmitter to confirm the adjustment.
To set the brake, follow a) step, then b) step braking to the maximum. You can now set your maximum brake end-point.
It is very important to perform these operations one by one.

Trimming
4
KT2S+ features two trimming functions:
2
Steering Trim and Throttle Trim.
Steering Trim Dial: Adjust the neutral
position of steering servo when the
wheels are straight ahead.
Normally steering trim is adjusted until the
model can keep straight tracks.
Throttle Trim Dial:
Adjust neutral position of throttle servo.
Make sure the model stays still when
3
releasing the throttle trigger.
