i still havent gotten the parts for my first project (come tomorrow), but im starting to plan ahead for my next. first question at hand is what length V is good for twin z drive blackhawks, http://206.206.85.209/xtdoc/Details....8&store=mhzusa, each with its own Nem Blue 12xl on 6cell lipo? i want it to be very very quick but it needs to retain some controlability.
