i decided to mod the chassis so i am now using 48t metal stock gear and 18t pin. Metal on Metal. question now is should the pin and the spur teeth line up exactly or should the pin be a little forward. I can not get the meshing just right, and its pissing me off. should it make a crazy grinding noise? what exactly am i looking for?!!!
