I'm looking at a used Hyper 7 and tring to figure out which model it is...the bottom of the chassis has Hyper 7L on it. The deal is the buggy, a new .21 8-port and pipe (53 i think), and a box full of spare arms, springs, etc for $400...good deal or not? My only nitro experience is with planes and all of my cars are electric so I'm feeling kinda vulnerable! thanks!
