the motor is still open as to what im going to use. I plan to have 1 steering unit total, and the output will be a 1/4 in shaft running the length off the car and servo horns or something similar attached in 3 spots, and the gearbox will have a worm gear in it so its very strong. I'm working it out in the 3d program now and ill show you what im talking about, but just like a standard sized motor like you find in walmart rc cars etc is all im looking for, since it will be worm geard down it doesnt have to be terribly strong.

I'm not sure if I would be able to build anything like that, is there anywhere to buy something already made for this?

Thanks for the help so far!
