tranny & diff ratio for emaxx 3905?
I was wondering if anyone knows what the tranny ratio and the diff ratio is on tha new e-maxx? I was going to use the rc monsters motor selecter[looking to go brushless] but didnt know the ratios. Any help would be greatly appreciated.

Well I opened it up and counted teeth. The tranny is a 18t top gear and 33t output gear=1.833333333
The diff is 13t pinion and 37t ring gear=2.846
Hear it is if anyone else needs to know

-Spur / Pinion X 5.22 = Final Drive (for 2nd gear, same as single speed on stock #3905)
-Spur / Pinion X 8.43 = Final Drive (for optional 1st gear, using close ratio gear set)
-Spur / Pinion X 14.45 = Final Drive (for optional 1st gear, using wide ratio gear set)
-Spur / Pinion X 8.43 = Final Drive (for optional 1st gear, using close ratio gear set)
-Spur / Pinion X 14.45 = Final Drive (for optional 1st gear, using wide ratio gear set)
