This was relatively straightforward; the motor is just a brushed motor so any off the shelf speed controller could work, and the RC car already had a potentiometer and brushed motor servo steering system. It was mainly just a matter of connecting the right wires, although I should probably use another resistor or potentiometer to compensate for the difference in resistance between the one that came on the RC car, and the one that was originally on the servo. However, I have not found the time recently to work on this, and it is a relatively minor project.
