All,
I must be missing something. I worked on my GT1 yesterday and discovered that any of the smaller spur gears will not work as the distance between the axle and the motor shaft is too big for a smaller spur gear to work. I tried a couple of different combinations and could not get anything to work other than the stock 33t spur gear.
Has anyone else figured out a way to use a different spur gear with the GT1 cars?
