Ordered a Mamba Max & CMS 5700.... Installed them and rear bearing carriers, alum idle gear, and got some various pinions to play with....

MUCH MUCH MUCH thanks to you guys for all the advice and suggestions... Incredible speeds and power... Pretty much solved my main issue... posted a review in the product reviews forum. I haven't really played much cause it got to dark out to see it between streetlights! Can't wait til tomorrow!
