Brian...here is what guys are running here....dynamite .21 (dont know which model but has a red head, the one running it in the expert class is always in the top 3) go.21 5 port (guy with the dynamites son, in a hyper 9 it hauls a$&) a novarosse 5 port and a couple others I'm not for sure...you will most likely have to run .21 unless you run in novice and your buggy comes with something different....

I have a 8 port sh and still trying to figure out why I dont have any low end....I'm hoping tuesday my answer arrives...lol



just found my trouble (didnt have time this week to tear down)....I assume when your clutch shoes are worn at the end down to the spring they are shot...lol...oh well life does go on,..lol
