6s would be cool, heck, im still trying to figure out gearing......but i guess it's kinda hard to do..since i don't have it, but from the info i have gathered,...running the following
7xl
quark 125b
2s2p (4s) 8000 maxamps packs
badland tires
the gearing should be fine at 22/68
i checked this on brian's calc. as well....., but on another note...can't wait for results on the 6s
