Got another sbp...took out the armature from the blue S2 motor and cut off 7 winds per side then dropped it in the sbp can and put the 12 tooth pinion back on. I hoping to get as much top end as the stock S2 but with more low end torque.
to my understanding (somebody correct me if I'm wrong), you killed torque. Torque, assuming all things are the same, is determined by the number of winds on the armature, but you did increase the top speed (rpms) of the motor. You now have a 40Turn motor.
