RE: E-Hellfire?...and a question about normal Hellfire
there are alot of rules that must be meet for it to be a truggy and for it to not be a monster
monster-center TRANNY, engine must be a certain height above the chassis (1.25 inches? don't quote me) and of course size restrictions.
those are wha ti can remember off the top of my head. Essentially a truggy is a buggy that has longer arms and longer wheel base.
