About 3 weeks ago the lower starter shaft bearing worked itself up onto the pinion gear during an aborted auto. I replaced the necessary parts and just recent, after maybe 3 trips to the flying field, the clutch is really siezing up. It seems to grab alot more at idle and even when Im trying to get it started. Today it was so bad that while holding the head with the motor at idle, something happened making a loud noise and te tail rotor started going!

The clutch shoes seem ok..

Does anyone have any idea what is wrong? Is there an end all solution to these clutch issues?? I tried the shim from heli proz and thats when the clutch started grabbing more. Today it got so bad I removed it after 2 flights, flew again without it, and then on the final flight is when the tail rotor came alive....

I appreciate any and all advice,

thanks,

scott

How did you set gap ??

When I got my kit I just glued the liner into the bell, and then melted the liner a bit ( Was new to hobby )


A site that helped me was http://www.raptortechnique.com

It sounds to me like your clutch shoe may be banging on the ceiling of the bell. The fan/clutch assy could be working it's way off the engine crankshaft or the ponion could be coming loose from the lower bearing. Also, if loctite was not used on the clutch bolts, you could have one of those working it's way into the bell. Pull the motor, check for wear marks.
