vta gearing?
i run vta and usgt with my 2 s411 cars my question is about spur gears and adjusting motor. to get my car in the 3.5 to 4.0 gear ratio i am unable to use the holes in spur gear to tighten motor screws.is there a chart somewhere to help guide me in setting up gears so i know what spurs and pinions will work so i can adjust motor screws through spur gear holes?
