Bondonutz · **3.3 Revo gearing -** 10.15.2009, 09:56 AM

I've spent some time BrianG's calculator and researching the forum and I'm having difficultys figureing out a pinion gear for my set up. The calc doesn't have a CD gearing, is it the same as the standard second gear ?

Any help will be greatly appreciated !

What I'm working with;

Revo 3.3 w/RCM mount
Novak HV Pro 6.5 3400kv
TRX center diff (ratio ?, Revo second gear standard ???)
Stock 38T spur
Stock diff ratios 37/13
4s 30C packs
5.5" LRP tires

I've read where some guys are using 19-20T pinions but with 2200kv Catsle motors so I don't want to guess where I need to be be with such a drastic difference in Kv's.

THANK YOU,
J
