BXPITBULL: that sucks...that's the only reason why I gave up on Cyclones. I just cant belive HB/HPI cant come up with a better diff design. Its pretty cheap on their part. I know some have not had these issues, but many poeple have reported those pesky screws breaking, nuts getting loose, and outright melting or slipping, and how dirty they get- to the point they have to be rebuilt after every race or so for them to work nicely. I personally have had all these issues, and nothing is more frustrating. I have built them according to all the tricks in the book, and the bes I've had lasted a few weeks by the time they got extremly dirty, even with the dust covers, or just staretd to snap, or get loose, etc. Its easy: if you have a great diff design, people should NOT have to be buyin other manufaturers parts and experimenting and tweaking to finally getting your product to work. HB has refined and inproved their bones, spools, cups, chassis, etc, but they have failed to work on this issue, and it really sucks...
I've gone back to Xray and Schumacher, where at least these issues are very rare.
