banx, the drive cup came off because the set screw backed off enough to let it slide off the differential axle... I like the copper pipe idea still, because it might keep the shaft and cup from falling off if it loosesn again. I picked up some Loctite for things like set screws, so I shouldn't have to worry as much about them anymore. lol!

As for the Meisenhut problem, I bet the clutch spring broke. If you have the two speed, excelhobby will not have the right parts, as it seems they only have one-speed clutch parts. I got the clutch shoes with spring, but the shoes are useless with this clutch bell; However, the spring is a perfect fit. You will have perfectly useless shoes out of the deal, but maybe you can sell them to someone here with a one speed buggy.

If ANYONE knows where to get the two-speed clutch shoes and bell, please post here!

(I know about the kevlar shoes from another brand that was mentioned... but looking for oem parts)
