Hey reaper!
I actually have some friends who tried to do a similar project. I suggest you start with the following parts:
- Motor (obviously)
- Motor controller
- RC controller and receiver, I suggest the RadioLink T8FB 2.4GHz 8CH Transmitter w/ R8EH 8CH Receiver
- Battery (at least 14 000 mAh)
- Linear actuator (to press the brakes)
- Another motor controller (for the linear actuator)
The parts needed will all depend of your needs and your current setup.
