on a old mamba 25, 3s, and It has done fine for probably 10 packs or so, but I am not really a hardcore basher. Needs a center spool or something, pretty much just blows the front tires off. I havn't had any other problems though.
I'm thinking of going direct outrunner brushless or 540 brushed to input shaft on tranny. If it's fast and fun enough I'll upgrade to MIP diffs. What KV would be good with 6-7cell nimh? Also does anyone have a link to a single standard servo conversion for the Mini LST?
