Gearing

Has anybody messed with the gearing? If so, what is the best pinion/spur for a 2s and a 3s?

18th tooth works well....... 20 lost the low end pop!!

what speeds are you hitting with the 18t?

I didn't check the speed yet.......... I do have the timing system so if I get a good day outside and can change out some Pinions and do some speed runs at 165 feet

im getting 66mph+ in 132ft with a 19t pinion.....I would expect 80mph+ all out.
