mod1 spur gears for e-revo

[shizzon]

after using the rc speed calculations as well as the gear diameter calculator i have decided on several options for gearing:

20t pinion x 46t spur = 45mph
22t pinion x 54t spur = 42mph

im sure i would be happy with the performance of either, but i cant find any mod1 spurs bigger than 40t. someone mentions associated MGT spurs but i cannot find any. it seems like it will be much easier to just get a 5mm 32 pitch pinion and use the abundant spurs for 32 pitch, but im ot sure if it will take a Nue 1515/1y on 4s.

please, if anyone has any gearing suggestions as well as where to get them it would be great
