Depends on voltage! I would say fast enough for most people trail riding :lol:
oh my god!!! i just ran my new sport 35t in my scx10 and its amazing!! sooo much power! i was running 14/87 and had plenty of torque/wheel speed for climbing mud. im so happy with it! but i cant wait to upgrade it to a hand wound. and i should be getting 2s lipo next week so im really excited to see what this motor can handle! and Holmes has excellent customer service and super fast shipping!
