i own a hyper 7 pbs and i have to say it really kicks @$$. it is a balance between a bashing buggy and a racing buggy. the buggy is very well put together. but when you get it make sure you go over the buggy and make sure all the screws are tight. and locktite all the metal to metal contact screws. and also go over the carb settings. i looked in the manual and checked over the needle settings before i started it for the first time, and the factory settings were way off what the manual said. i reset them to the MANUAL factory settings and the car started right up and continues to start up on the first or second pull every time. i have a half of a gallon through mine and i have to say that i am impressed with the hyper 8 port. it is a screamer. and also with the hyper 7, if you break it then it is VERY easy to find parts. and ofna's customer service is pretty good. that is my experience with ofna. they make good stuff.
