The vehicle does not stop when the throttle/brake lever is released
•
Correct the driving trimming on the transmitter (setting neutral position).
The vehicle slows down or the steering servo shows only slight or no reaction; the range between transmitter
and vehicle is very short
•
The drive battery is weak or discharged.
•
The receiver power supply and thus also the power supply of the steering servo is achieved through the speed
controller BEC. Therefore, a weak or discharged drive battery will cause the receiver to no longer work properly.
•
Replace the drive battery by a fully charged one (before inserting a new drive battery, wait at least 5 - 10 minutes
until motor and speed controller have cooled down sufficiently).
•
Check the batteries/rechargeable batteries in the transmitter.
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 or 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.
Driving works opposite to the movement of the throttle/brake lever at the transmitter
•
Usually, the vehicle should drive forwards if you pull the throttle/brake lever at the transmitter towards the handle.
•
If this is not the case, activate the reverse setting for the driving function at the transmitter.
•
If the motor was disconnected from the speed controller (e.g. for maintenance purposes) and re-connected again
later, the motor cables may have been swapped. Swap the two motor cables.
The steering is not functioning or is functioning incorrectly, steering deflection at the vehicle insufficient
•
If the transmitter offers dual rate settings, check these settings (observe transmitter’s operating instructions). If the
dual rate setting is too low, the steering servo will no longer react.
• If the transmitter has a setting for the end positions of the servo deflection (e.g. designated "EPA", "Endpoint adjust
-
ment"), check them or correct them.
•
Check the steering mechanics for loose parts; e.g. check if the servo arm is properly attached to the servo.
The driving time is very short
•
Charge the drive battery or use a different, fully charged drive battery.
•
When using a NiMH-drive battery, the undervoltage recognition should be deactivated. Otherwise, it is not possible
to use the full battery capacity when driving the vehicle, and the driving time will reduce (see chapter 10. b).
The drive battery heats up when charging and driving the vehicle
•
This is normal.
