What gear ratio (spur, pinion, pitch) and FDR would you guys recommend for the following motor:
21.T Brushless
Silver Can
27T Stock
So looks like the magic number for Silver can, Tamiya Black Can, and 27T is around 5.5-5.6 FDR. Reusing what I have it seems like I can do 64 pitch 112T spur and 40T pinion.
Magic number for 21.5T Brushless is around 3.5, was wondering if I can use a 48pitch 69T spur and 38T pinion. Will those two gears mesh together?
