yup microcenter the one here in new york they have like 20 left and the motor is a 29 turn pos iam going to open it up and take like 3-4 winds off the armature on all sides then reassemble it and see what that dose, glad to see that you took my advice and rebuilt them i think they had like 10 or 15 wt in there so the 30 was way better 40 will work also you don't want to go any higher than that being that the car isn't that heavy compared to the 1/10 scale.
