yeah, it would be easy to mod the thing to work with the steering. For the brake, I would say take a reading of the "pot" at dead center and full gas. For brake do the same. once that is done wire them up and test it out, hope that helps, cool idea for a telerobot (with a cam. on it). If it is an electric I would mount a cammera and a radio system so you can talk to all the amazed kids... To see somthing like what you want to do goto
