thanks both of yu guys, well i dont race and never plan on it I just enjoy bashing in my back yard, I have a Rustler and a Pede i also have a Nitro rustler that I really dont like being nitro thought about making it Electric maybe wonder if a system like this would be good for any of my truck. I dont care about wheelies I knwo with a killer system it will if your not easy on the throttle. I am running 6 cells right now might get some 7 cells later on.
