that thing hauls azz! So what kind of radio do you use for that? I would immagine it would be a stick radio for airplanes so you can control each track independently?
It's actually a single motor with a differential with left and right brakes off one servo that steer a blizzard. Turn left and the left track locks. Turn right and the right track locks. Any radio would work.
