Update: Took the truggy out this weekend for some testing. The clutch worked great and really did smooth out the brutal brushless power delivery. It felt almost nitro like with a lot more snap, but it was kind of weird because there was no nitro noise. Unfortunetly about half way thru the day I again stripped the plastic spur after landing hard. Apparently the clutch does not offer as much slip in this situation as I had hoped. I had a back-up diff with a steel spur that I mounted in the truck. I ran the rest of the day with no futher issues. Wear on the steel gears was minimal at the end of the day. I am still concerned with the stress on the drivetrain (enough to rip 4 teeth off the spur) so I would have liked a little more give with the clutch system (guess I have to wait for the slipperential). I did like the way the clutch smooths out the power delivery. So I now I need to decide if I should run the clutch or go with a hardened pinion and eliminate some of the complexity/maintenance that comes with using the clutch setup. I think I will run it as is for a litte while longer then decide.
