try to see if the slipper clutch came loose... maybe teh engine moved away from the spur..... and check the drive train like if it uses the hex adaptor for the wheels and the pin came out that could be y

spur gear sounds chewed up

there might be a oneway bearing inside the transmition.I had one in my thunderquake its did the samething.or do you have plastic cluch shoes and did they melt?

"theres a huge circle and 2 metal things comin out and a hex nut. the nut spins with the piston but not the big circle thing with the things comin outa it."

Dude, is this coming out of your engine? If it is...


This sounds like the fly wheel. The two "metal things" are prrobably what hold the clutch shoes on. And ofcourse, the hex nut is what holds the fly wheel on.

Tighten down the hex nut.

What is it?
