The way it was spinning in the beginning of the video I had to wonder if the pilot had lost tail rotor control or if it could have been his first solo flight. and he had over corrected. It appeared as if the pilot had regained control and was trying to land but again lost control. Or on the other hand could it have been an intermittent fault in the controls. I don't see a windsock so no way of knowing if wind may have been a factor.
