UPDATE!!!

I was flying tonight and was on the 3rd battery. I was practicing turning a right circle and came into a hover. After about 30 seconds the heli made a violent shake and I could hear a buzzing sound. Then it fell like a rock from about 3 feet. I examined the wreckage and one of the tail blade grip screws that hold it to the spindle came out. One of the tail blades departed in flight. I found it and the grip, bearing and screw were still together.

After a complete inspection and some new parts I should be in the air in a few evenings.

Mrashtray.
