I run a 6.5T in my Losi 22 and have a final drive ratio of 9.23 (20/76). This could be a good starting point as it gives me a good balance of speed/acceleration without getting too hot.

Lets see if ive worked this out right.........PLEASE correct me if im wrong
(B4 internal ratio is 2.6)
my LRP Eraser 9.5t brushless motor recommended final drive ratio is 9.4:1 so for me to get that ratio or as close as possible
(with the only spur gear ive got 81),
I would have to run a 22/81 pinion and spur combo to give me a final drive ratio of 9.57...........???
And think ive read before that if needing more acceleration drop done 1 tooth to 21 or for more speed up 1 tooth to 23 but not recommended to to go up/down more than 1 tooth.........???
cheers
