Default What spur and how to on math for ratio ?

What spur / pinion gear are you folks liking on the AX ? is a 66 to big

And what is the math equation to find ratio on any 3/4 gear tranny, Stealth, pede, Axial ?
I used to race and have the little charts but that was a looong time ago

Thanks

OMG That is badda$$ good buildin Kmz I think I'm convinced to buy one now :-P

But I'll have to make it a realistic tuber.


Thank you Yotachump-
After destroying my rc4 trans I was very happy My Axial trans holds up to my BM16 outrunner on 8 cells , I had the tires spinning and lock stopping in the garage
I was using a 32 pitch 48 t spur and a 20 pinion

the crawler store sells the 48 pitch 87t spur, so I'll try that on the rocks

First pic is a 32 pitch 66 t
