Hmm, I was under the impression that many of them were interchangeable because they were primarily built on standards. I knew there were some differences, like Kyosho style was different from OFNA which of course is different from Losi. Good to know. I am glad I didn't just buy anything.
I am looking for a cheaper replacement for my xray 808. The xray clutch bell comes with bearings, and I prefer to replace my bearings with other brands (typically Avid) anyway, so I don't want to pay more for the bearings that I just replace. I have many Losi clutch bells and I know those are different (longer). I also don't use the xray clutch setup, but rather the Fioroni Turbo Sliding. Any suggestions?
