Anthony, as long as the motor has good compression then your safe. It is a matter of bolting it on and setting the mesh. The electronics are fairly easy - almost plug and play. If you have wired your own lights for a tank then the servos and receiver will be a breeze.
Mike, www.towerhobbies.com has some really decent AM radio systems w/ 2 servos really cheap.
This is a very decent car and easy build-up for anyone that wants to get started, especially for the price. Now Jim if you want to sell what goes with that truck body in the background for $75 I'm all over it.LOL
