As for experiments- it IS more fun to just have the machine throw Big Mike around.......

And its probably the only thing that can throw him around...
As for the wheels, the custom made Skyway wheels with diamond cuts on them makes them stick to the carpet like crazy(traction). Then, Straight-cut spur gears along with needle and ball bearings ensure all the motor torque gets to the wheels with minimal parasitic loss...
Thats the explanation I got from our tradesmen.
