and lastly.. the car has a metal spur gear and a metal pinion. these two seem pretty noisy and people at the track have commented on it. i reset the mesh but it doesnt seem to make a difference. also the spur gear itself seems to have quite a bit of play front to back and i have no idea if thats normal or cause for concern.

any help is greatly appreciated!
