The hottest class in oval racing now is 21.5. We have the motor of choice, the Novak SS21.5

SS21.5 Pro Brushless Motor is 21.5 turns and is the slowest motor in the SS Pro Series. It was specifically designed to offer oval and beginning drivers an even slower option, which makes it ideal for extended run times (#3421).When using a 2S Li-Po pack, the SS21.5 Pro brushless motor can match the speed of the Novak SS10.5 Pro (#3410) brushless motor on a 4-cell Ni-MH pack.
