Well I got 41mph. That is with a heavy battery that does not fit all the way, my Motorola phone and a short street. It was hard to keep the front wheels on the ground. I would expect to see higher numbers on a longer street, parking lot or whatever. That 2400 kv motor takes some serious geering and battery punch to make it happy. Oh, the motor temp was 127 deg. After eight min. Of speed runs. That is just one reason why I bought this motor(lower operating temps).
