Has anyone done any gear ratio changing on the aurora 4 gear or AW 4 gear chassis. Getting rid of the 9 tooth pinion gear and using a 12 or 15 tooth replacement. I would think a 12 tooth would be easiest all you should have to do is find another smaller large idle gear and relocate the pin. I came across an article a year or 2 ago but can’t find it. Does anyone know where you could find the proper size idle gear.
