Ok, a 17.5 is rated at 2,200 kv (15,840 rpm). A Tamiya dirt tuned 27T is rated at 17,000 rpm. Seeing ratings like that, I am not so sure about your last comment about my 20T being blown out of the water. Especially considering that a 27T motor is rated for more rpm at 7.2v than a 17.5 is rated at for 7.4v.
Guess I will just see how my brushed motors and my gearing stacks up to the competition in sportsman class.
