With those foam tires you need to control the tire spin or you'll wear them out quick. Don't stab the throttle ease into it and try not to spin.

Thats a description of the Pressure angle. It seems as though it really wont matter, but the 20* is becoming most prevalent.

It specifically says the teeth that are meshing must have the same pressure angle, So those gears wont work with my set up or spur. The plastic ones will but I still don't think they are strong enough.
