Dont crash it :P lol its a fun car, flys through the air nicley, make sure you run it in right, and dont use a roto start, it diddnt turn out right for me (struggled... and drill broke it). Starter box is working fin for me, and dont go too high % fuel (ithink its 30% or higher is too high). I use 20% and its fine, nice acceleration and top end. I would get some on road tires if you run in the street aswell.
