wow.. sorry what knowledge? I built the car and run it out of the box.. clutch sucked.. never happened with Kyosho or even with CEN. I've been buggy racing since 2004
I switched to Kyosho 3-shoe and run the whole day, very well and better actually, and the composite clutch is still in great shape
I admit the clutch (the whole flywheel assembly) is easy to remove and work on, but that's it. I'm talking about the version 1.0 (not the 2.0)
it's not the only poor clucth tho in the market
if there's any more "knowledge" please do share it. This was just my experience on the car and it's clutch. The car itself is great!
