22 teeth pinion have the same diameter as pinion 21 and same dia as 20 teeth on the V-One -R.
Kyosho said the advantage is u don't need to space the engine to accommondate different pinion's size. However this is my questions -
If they are the same diameter on all the second gear's pinion, don't they travel the same distance per Rev .!!!! Need help.
then using 20 or 22 teeth would be the same speed
