11. Troubleshooting
Even though the model and the remote control system were built with the latest available technology, there can still
be malfunctions or errors. For this reason, we would like to give you some information on how to deal with possible
problems.
Also observe the operating instructions on the remote control system used by you and the motor and speed controller
installed by you.
The model doesn’t respond or does not respond properly

however, it can, of course, also be done by you. Observe the operating instructions for the remote control system
used by you.

rotated by 180°, the speed controller and steering servo will not work.
If, however, the speed controller and steering servo plugs are swapped, the throttle/brake lever controls the steering
servo, and the wheel controls driving!
The vehicle does not stop when the throttle/brake lever is released
