From what I have heard one of the guys from Castle Creations ran some Mambas on a Power Wheel Jeep I think. Could be a little off on that one, but I saw a video of it a while back.
It actually has one (what I beleive to be 540 can) motor on each rear wheel. With two 4600 MM's I bet it would haul. I can't imagine putting that kind of money into it. So I may start out with dual Tazer ESC's and come up with some sort of servo setup for it. Not sure what servo I'll use. Any idea what a large cheap servo is?
