Unless your track is really short or tight I would be aiming in the 3.9-4.5 FDR area. WE run on a med length open asphalt track and my car is geared 4.1ish FDR. Start with 4.5FDR and gradually gear taller while checking motor temp. Too hot will destroy the magnets, but you need tall gearing to make use of the torque these motors have.
