Well it depends on the kind of game and what is needed. This year we used the gear boxes from the kit, but built our own frame out of Bosch, because its really simply to use as stated above and provides you with infinite possibilities as far as position of the tires goes.
Last year, out team actually built the
Ackerman Drive System. It was really cool, until we had a system breakdown, tow days before the shipment, and have to switch the whole drive system to the kit drive system.
