Using hardened steel R.R. spur on 5mm 32 pitch pinions

[zeropointbug]

Just to make sure everyone knows what im doing, im not running it through a tranny. I will have the spur connected directly up to the diffs from CVD's of course... i don't know if you knew that?

Im a little stuck for gearing though, im thinking 14 or 16 tooth pinion with a 66 T Spur directly to the diffs with 7XL on 5s2p A123 pack.

Well, way back when i had my stock emaxx, i bought the R.R. Racing spur and ran it, WOW, filings everywhere, it was noisy too. And seemed to be slower.

Exactly, i don't see an advantage running Mod1, 32 pitch in my opinion is big enough, and would be more efficient and quieter.

BrianG, what gear ratio do you think i need, 14 or 16 tooth, thats running RD Logics Spikes tires, i have some 20, and 22 tooth for 1/8 tire running also.
