I have the old school rc10gt with a os.12 cv-r. Im sure all of you have expierienced frustration with e-clips. There is a large e-clip on the end of the crankshaft holding the clutch bell assembly together. Since that e-clip is always spinning at hi speed, it comes off. Why? I DON"T KNOW!! I have gone through at leats 10 e-clips and 10 clutch bell bearings which arent cheep (about 7 bucks a piece) plus i've gone to two hobby shops who could not help me. I have tried wire, washers. etc. They all come off!! So if you have any ideas, please post. Any input is helpful. THX!

make sure its seating all the way in the groove. i used to loose them once in awile but it was usually bc it would be a little crooked. if that dosent help then the clutch nut groove could be worn out a little too much. (try a new clutch nut)

Not real familiar with the rc10 but i'm assuming it has a pilot shaft that screws on the end of the crankshaft to support the the cluthbell???? If this is the case you should be able to get a new pilot shaft that has a threaded end to secure the clutchbell instead of the eclips.
