I have one with a cc MM/5700 2s lipo and I just got back from outside with it. It's designed for snow and only snow. I have ran it on multiple surfaces and so far the only one it performs like it should on is snow. I think it has to do with the lack of traction it gets traction on just about any other surface and just spins out but on snow this thing is just awesome. Plus I have some LED lights on the cab for scale looks/night driving.
