Some one might know the Maxx diff ratio, but we need to know what pinion and spur your 'pede box runs.

Ok, your looking at, with that 2:1 reduction in line, 33.8 : 1, at the prop shafts. When someone comes up with the maxx diff ratio, multiply that figure with that one... 33.8 X [Maxx ratio] = your overall gearing.

Maxx ring and pinion ratio is 2.85:1... That was ALL I could find, too... That seems like to be the #'s needed anyways, yes? Found that from a site that takes Ofna 7.5 gears and stuffs them into a new case for the MAXX and has a new ratio of 3.31:1... |
