i wanna put my 23-toothed spur gear in my slash. it dont fit. i have the stock 86t pinion gear in.please help.
ok, i got it in, and when i pull the trigger on the transmitter, it makes kind of a whoosing/whistling/screatching. now it was makin a whine befor i switched the gear. is it supposed to whoosh more with the 23t?
