Nice flight today, but a strange end:

May be aft right motor failure. Look it frame by frame from 19"00. I am somewhere with a red jacket.

No apparent damage?

Enjoy,

I didn't hear a sudden failure like a motor making odd noise and failing, and you didn't indicate whether you were missing a prop or not. However, I did hear an ESC beeping just as it hit the ground. That leads me to think it might've lost power during flight and the wiggling around as it was tumbling caused it to reconnect again. I would make absolutely sure your wires are soldered well. If you have loose wires, this is what will happen.

Hello,

No prop loose or missing, but after crash one of the Rear Right Esc plug was unplugged (beep).

It was my first video with APC props, with a lot of vibrations. I did a prop balancing today. Expect some update this afternoon.

I was expecting a hint with prop noise variation also...

Yep, unplugged ESC would do it. Unless you can guarantee that those plugs won't come undone again during flight, I would suggest soldering the wires together.
