Hardened Pinions

[Nick]

I bought 3 from Mr Constructor but they all just wore out.

Going to try RCM ones but do you know why the others could of stripped? Meshing maybe?

Also, what gearing should I go for, I run a 7XL on about 16/18 cells. Want it top end really. I think the spur is a 55t for EB4.

Thanks,
Nick.

For on a buggy I think a 16 55 should be pretty good. I ran a 14 51 on mine 16 cells and it was pretty quick.

Can only get 15t from Mike. So 15/55 sounds good.
