well there is one big problem.
you have to use the transmitter/esc whats in the car for the "servo" if you look to the
picture you see there are 5 wires to the front of the car. thats probably for the steering. and the "normal" receiver does not have a 5 pin connector.
maybe i am wrong but that would be a problem cuz you are not going to use that esc/receiver....
