Re: What teams have desgined a 6 wheel drive system?

We lowered ours 3mm (close to 1/8") and we could spin like a top.

To the point of traction: if all the motors are geared together per side and then run to the wheels, the lowered center wheel does not reduce your tractive effort (pushing ability). A six wheel drive concept is like using powered castors. The design is such that the center wheels take most of the load and the outside wheels balance load when the CG is moved on either side of center. If the drive is designed correctly, you pushing ability is not reduced as long as all the items touching the floor are powered.
