Next flight kind of similar flying, and then poof. It was hot. ESC powers up with no errors but motor just tries to turn very jerky. So I will put my spare motor in tomorrow and drop down to a smaller prop.

Cest la vie
Dang... Sorry to hear that. There is a possibility since the motor fell off before, that it possibly weakened a lead wire. Vibration could have taken it the rest of the way. Put a VOM on the leads randomly and see if you have lost ohms on one. You should get tone from all. Then see if any of the lead wires have grounded to the shaft, case, or bell for a direct short.
