yea im pretty tame but love the power on tap and like to show off a lil bit when im just having fun, ive ran it on 5s with a 2200 and know it needs more power for what im comfortable with but maybe 5 s would be good for the muggy with a 1521 but its a big truck and deserves a big battery, i know it inside and out and am not afraid to do rebuild it if it breaks i just love the break neck speed of raw brushless power and want to show it off with my muggy
