So, in the above picture, 1 or 2 motors turn a spur-gear on one side of the Baja that rotates a shaft that has a pinion-gear attached to it on the other side of the Baja that then turns that actual spur-gear of the Baja? And the bearings on that shaft sure do look small, and it looks like there's just one bearing on the left-side by the pinion-gear...

Anyway, I agree with what has already been said, that contraption above is just a total mess, with completely unnecessary components, parts and layout...and it will probably bend on the very first impact, or maybe even during installation, heh!
