Yea people shouldn't post unless they know what they're talking about, you'll just confuse people. The rc10-gt doesn't use springs, it never has, it probably never will. Its just got two little shoes stuck on two little pegs that flop around aimlessly but work like a charm So anyway mascun i'm having the exact same problem you are. My wheels are spinning at idle and if i brake it kills the engine. Its not imediate, takes a few seconds, but its getting worse. I figured my shoes were worn out so i popped off the bell and took a look and they look OK but i think they are still worn. I think over time they loose some weight little by little (all the fine dust when you take your bell off, thats your clutch shoes wearing) and after a while they'll become too light and will stick at lower and lower RPMs. Eventually it will lead to idleing wheel spinnage just like you and I have. I ordered some new shoes which should be in tomorrow. I'm 99% posative this will solve my problems, and if it does i'll let you know!
