Truck is almost ridiculously light in stock trim and very fast on only a 7 cell nimah (have not decided which way im going yet on lipoly) my only concern is long term parts support and possible some parts breaking down due to weight savings vs strength though i am surprised that i have ran it every single day pretty hard and not broken a single part only real limit seems to be 70a ESC which limits you to only 2s packs got another on the way so i can go up to 4s power ..motor in this set-up very nice .. i have made quite a few changes to make it more monster truck like i'll show later in the week ...
