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 slows down or the steering servo shows only slight or no reaction; the range between transmitter
and vehicle is very short
• Thedrivebatteriesareweakordischarged.
The receiver power supply and thus also the power supply of the steering servo is achieved through the speed
controller BEC. Therefore, weak or discharged drive batteries will cause the receiver to no longer work properly.
Replace the drive batteries with new, fully charged ones (before inserting a new drive battery, wait at least 5 - 10
minutesuntilmotorandspeedcontrollerhavecooleddownsufciently).
