[Overdriven]

Oh, ok. I was wondering why NONE of the pics had the brake on the center diff! Brakes on the wheels get my vote then. If he's got a machinist to make the motor mount, make some new discs with the 22mm hex in them. I'd think that would be less expensive than machining a new shaft and mount for the center diff to accomodate a brake. Plus brakes at the wheels would be more powerful and fade resistant, important considering the weight of this thing.
