The HPI Sprint 2 is a nice car, I have one too (yes I know I have too many
) It's really smooth to drive since it's belt driven, but like any other rc there's some mods that you will have to do to make it run better. My setup has the Sidewinder/5700 combo & it hauls. Right now I have it setup to do drifting, wanted to try my hand on it. Forget the E10, that's a beginner car.
