Thats why I was looking for a smaller pinion. Even with a 12T it is still in the mid 50's. RC Monster doesn't have pinion smaller than 15T. The company that we are getting the spur from sells pinions. They call them a spur with hub & set screw though.
Are these Mod1? If so, Mike has down to 9T pinions... or are these Mod1.5 pinions?
