This is my smartech rc. It was nitro but i blew the engine. So i got bored a few weeks ago and took apart my rustler and threw the diff into the smartech and it surprisingly worked. Its not the greatest drift car, but its still fun. It has a 19t Fireball, XL1 esc, traxxas high torque servo, Duratrax 2000mah NiMh batteries, Traxxas connectors. I put spray paint caps on all four tires. On the front i wrapped them with some pvc tape for a little bit more traction to help steer. It works pretty good now. Only problem is the speed, its kind of slow because of the conversion and gearing. But it will do for now!
