My car starts to go as soon as I plug in my battery pack. What should I do?
Make sure that you always have your transmitter turned on before you plug in your battery pack. If you send power to the receiver before you send it a signal, the receiver will pick up stray signals and cause your model to act erratically. If you have your transmitter turned on when you plug in your battery pack and the car still takes off immediately, you will need to re-center your throttle servo. Basically, all you do is unscrew the mechanical speed control from your throttle servo. With your transmitter on, trim settings at zero, and batteries plugged in, adjust the speed control to a neutral position and screw the speed control back onto the servo making sure not to bump the speed control out of its neutral position.
