The auto bearing slipping under power. Replace the auto hub and the main gear.

A blade strike would do it. We need the details! heli? engine? etc...

One of 2 things. Either the gear was faulty and had a hairline fracture or it was overly stressed for a short period of time becuase of the auto hub slipping.

Stripped Main Gear

I have seen this happen twice now. Fortunately not to mine. In the first case it happened in a crash but interestingly the second time was on a landing approach. The heli had been switched back to normal mode and was on a fairly shallow landing approach. The engine was transitioning between 2 stroking and 4 stroking all the way down when suddenly the teeth on the main gear let go. It was auto'd the rest of the way down OK. Now I do mean the tuning was exactly wrong. You do want it to hold a constant RPM when idled back.
I hope this helps.

If you ain't crashin', you ain't tryin' 'arrrd enough
