Just got my b4.1 worlds built, first it ran sluggish, then watched the how to build diff (thanks vid poster) and tighten the diff bit more, now no sluggish but does wheelies, lol! i got a 7.5 tekin on 22gear, is it the best way on the tekin pro esc to just turn limiter from no limit to 80% limit to stop wheelies or is gearing better more efficient?
