I have and old usless rustler, that i just took the rear end off of, made it about 3 1/2 - 4 inches norrower, and tomorrow im going to connect it to the chassis. I thought narrowing it would the the hard part, but i cant figure out how to connect it to the chassis.
I put the 12s in and on 8 cells it got up to 35, it didnt even have enough power to wheely, and striped the gears.
