Hey everybody I'm new here and already got some questions. Just picked up a nice xs flux, which of course has a few problems. I've read about the metal for the cups are week and the ones on my transmission are the worst. Should I stick with genuine Hpi HD parts, or are the hot racing tranny cups just as good. I wanted to do the HR HD drive cups with the hpi center universals. Is Hpi the only one that made center universals? I've also had a hard time finding good bearing sets for it. I like avid but cant find them. And I don't have much experience with fast eddy or boca.
