On a Clod the motors and gearboxes are mounted directly on the axles. So there is one motor on both the front and rear axles.
When you build a crawler from a stock clod, you take the rims, tires, body, and complete axles off the truck, and throw eveything else away, lol. The rest of a stock Clod is useless for a crawler, these are the only parts you will need.
Hey if you guys put together a list of what parts you want I can come up with a "RCNT Brother-In-Law Tatoo Wearing" price list
Just fyi the Novak system would be $147+ Shipping
