Ok, now first of all lets make sure you are all up to speed: The electronics in any RC car are generally made up of three seperate boxes.

servo: has gears inside and is for steering

receiver: is what the ESC (speed controller) and servo is pluged into. This unit has a frequency crystal
plugged into it and has an antenna wire. It takes the signal from the remote and translates it into instructions (electrical pulses) for the ESC and servo.

ESC: This stands for electronic speed controller. This box regulates the speed of the motor by cycling the motor on and off very fast or slowley depending on what output speed is desired.
