I race at a track with no motor limit, what motor turn is best? I really like fantoms stuff. Any help? I pref. Brushed

It totally depends on the track and how much you and your car can handle and still be driveable. You'd be surprised how many times a 17 or 19 turn will get you faster laps than a 10 turn.

As my good friend Mr. Putnam would say, "you can't fire a cannon from a canoe".
