Just got a XXX4 with 4300 brushless. The guy I bought it from said he raced a zx5 with the 5800 and they where pretty even. I raced the same zx5 against my rc10gt and we were neck and neck for like 10 laps. then he crashed :). anyway does anybody have some tips on setting this thing up. It is pretty much set but it likes to nose dive off jumps. maybe I'm just to used to the rc10gt.
