I am building it for fun, and am trying all sorts of variations on control, from autonomous, IR using a tv remote, RC spectrum receiver, to wifi. Tried a couple of different cameras, 900mhz to a receiver, and an IP camera.
The motors have spenty of power to spin on carpet at high throttle.. The biggest disappointment with the platform is the adverse effect on traction that having no suspension has. A small lift at one corner will take the weight off two wheels on the opposite diagonal. It needs suspension travel to maintain traction at slow speeds and not rely on inertia from speed.
It will climb severe angles on a flat surface, or straight up a wall or stair and roll onto it's back. I am thinking about various suspension ideas. A swing arm would be the simplest. Perhaps with a torsion bar between them, like the rear of an old volkswagen. Not sure how that longer wheelbase might adversely affect doing a tank turn.
