The vehicle does not stop when the throttle/brake lever is released
• Correct the driving trimming on the transmitter (setting neutral position).
• If the trimming path is not sufficient, reprogram the neutral and full throttle positions; see chapter 10. a).
The vehicle stops
• The overtemperature protection of the speed controller has been activated. The green LED at the speed controller
will flash and the motor will emit a beep every two seconds. Wait for a few minutes until the speed controller has
cooled off sufficiently.
• The undervoltage protection of the speed controller has been activated. The drive battery used is flat. The red LED
at the speed controller will flash and the motor will emit a beep every second. Replace the flat drive battery by a fully
charged one.
• The vehicle is too far away. The speed controller has switched off the motor for reasons of safety, since no valid
signal is sent by the receiver. The red LED at the speed controller will flash and the motor will emit two beeps every
second.
This may be different if the receiver used has its own failsafe function. Observe the separately enclosed
operating instructions for the remote control system.
After switching on the speed controller, the red LED at the speed controller will flash and the motor will emit
two beeps every second. The motor does not start up.
• Check that the transmitter is on.
• Are the batteries or rechargeable batteries inserted in the transmitter or are they flat?
• Release the throttle/brake lever at the transmitter and put the trimming of the driving function to the centre position.
Otherwise, the self-test of the speed controller cannot be completed after activation and the speed controller/motor
will not work for reasons of safety.
• For 2.4 GHz remote control systems, the receiver must be taught to the transmitter. This process may be referred
to by the terms of "Binding" or "Pairing". The teaching process usually has already been performed by the manu-
facturer; however, it can, of course, also be done again by you. Also observe the separately enclosed operating
instructions for the remote control system.
If the receiver has not been bound to the transmitter, it cannot pass on a valid control signal to the speed controller.
In this case, the speed controller does not work for reasons of safety.
The vehicle doesn't drive in a straight line correctly
• Set straight driving at the transmitter using the respective trimming control for the steering function.
• Check the steering rods, the servo arm and its screw connection.
• Did your car have an accident? If so, check the vehicle for any defective or broken parts and replace them.
Steering works opposite to the way the turning wheel is turned at the transmitter
• Activate the steering reverse setting at the transmitter.
