Pushing forward throttle trigger the model moves backward while pulling back,
the model moves forward. If necessary you can just use a small screwdriver to
adjust the corresponding switches.
CTX-8000 features two trimming
functions:
Steering Trim and Throttle Trim.
Steering Trim Dial :

servo when the wheels are straight ahead.
Normally steering trim is adjusted until the
model can keep straight tracks.
Throttle Trim Dial :

rear wheels stop rotating when throttle
trigger remains in NEUTRAL position.
Trimming
Dual Rate Dial enables to adjust the same maximum steering angle of servo on
both sides (Left and Right) when model makes steering. The Dual Rate Dial 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.
