If the neutral position is not correct (e.g. trimming control slightly off), you cannot switch between forward
and reverse driving. If you have this problem, correct the trimming settings for the driving function at the
transmitter.
Please observe that the speed controller recognises the current position of the throttle/brake lever at the
transmitter (or additionally the trimming for the driving function) as neutral position after switching on!
Stop driving immediately if the vehicle shows unusual responses to the remote commands or if the vehicle
does not respond at all.
This behaviour could be caused by low driving batteries, low batteries/rechargeable batteries in the re-
mote control or by too great a distance between vehicle and remote control.
A coiled telescopic aerial, disturbances on the radio channel used (e.g. radio transmissions from other
devices) or adverse transmission/reception conditions could also be a cause for unusual responses of the
vehicle.
Never point the transmitter aerial directly onto the vehicle. It will decrease range!
Since the receiver is supplied with power through the speed controller BEC and thus through the driving
battery, low or empty driving batteries will cause unintentional movement of the vehicle (e.g. twitching of
the steering servo, etc.).
For example, the voltage of the driving battery decreases for a short time under full throttle, so that the
receiver will no longer receive the required operating voltage. The vehicle will speed up, but the steering
servo does not react properly. Stop operating the vehicle at once and use a new, fully charged driving
battery.
Before inserting a new, fully charged driving battery into the vehicle, wait at least 5 – 10 minutes until motor
and speed controller have cooled down sufficiently.
i) Stopping the Vehicle
To stop driving, proceed as follows:
• Let go of the throttle/brake lever on the transmitter so that it goes into neutral position, and let the vehicle run out.
• Once the vehicle is stationary, remove the car body and switch off the speed controller (for switch position see figure
chapter 8. e).
Make sure not to touch the wheels or the drive mechanism, and make sure you do not move the throttle/
brake lever at the transmitter!
• Disconnect the driving battery from the speed controller. Disconnect the plug-in connection completely.
• Now you may turn off the transmitter.
Attention!
The motor, the speed controller and the driving battery become hot during operation! Do not touch these
parts immediately after operation. Danger of burns!
