Pinion gear teeth/ motor turn chart..

[DusterX17]

Hey there,

i was wondering is there some sort of standard chart for the number of theeth a pinion gear, (and spur gear) should have for various turn motors?

brushed and brushless (cus brushless can handle 2 teeth more because of high torque right?)

i know its 24 theet for a stock motor, and 23 for a 14 t motor, so what would you use inbetween? (like 21t.. 19t?)

correct me if i'm wrong thanks :]
