I assume you are running on a hard surface? Try the optional 62 tooth spur gear....just check the temps to make sure things don't heat up too much.
watching temps of course. I run 20/54 all the time.
I'm not krazy. My mother had me tested.
Have you checked to see if the esc is set for 100% forward speed? Also if you have the telemetry and ipod check to see that it isn't set to training mode? Just a thought.
