So I have an hpi mt2 completely stock, and my buddy has a hpi e-firestorm. He just got a sidewinder esc, and a castle creations 5700 motor. We did some speed runs today and his launches quite a bit faster than me and our top speed is about the same. I figured that his would launch faster than mine, but I thought that I would be able to pass him in the top speed. Guess not.
