Webillo,
Ah, so if the steering moves left when using the motor test page then that means that SERVO1_REVERSED is incorrect. The steering is reversed which explains why the vehicle would drive in the opposite direction from where it was intended to go. Once you correct that you’ll probably find that manual doesn’t work anymore. the best way to fix this is by reversing the PWM direction in the transmitter, if that’s not possible then I think you can change RC1_REVERSED.
