No problem Mike, I got the private message. ;)

If the spur is the gear next to the pinion it's 48 teeth delrin I think.

I'm not really sure what would be the best way to solve the problem. Higher voltage would need a bec unit (more cables) or a receiver batt, a slower motor would be slower ;).

Would the MGM 120 help?

Changing the pinion might help, but if the 13t pinion gets the controller to 80C° in less than 2 laps it might not be enough to change the teeth count by 1 or 2...
