my first and only RC is my arrma kraton had it since this last Christmas an have spent 800$ on it (340$ for the car, 300$ for lipos and a charger, and the rest in repair parts.) I have 300$ of free upgrades in it courtesy of arrma, and a 22tooth pinion gear with a stock 55tooth spur gear, i have bumpers from tbr and a savox steering servo with a novak racers glitch buster the 6s packs im running are the new turnigy graphine battery's. the diffs are blown atm and it's gonna take a machine shop to fix because the screws are locktited and I can't remove them without stripping it, before that this thing I feel could easy hit 100 mph.
