The aircraft in the video is not in an incipient spin or a developed spin, it is a lateral departure from normal controlled flight. You may wish to argue that point, but there is no evident yaw in the video, so incipient is unlikely, and developed spins exhibit rates of pitch roll and yaw at the same time, (unsteady may alter 1 or 2 of those momentarily as they reverse or are just unsteady). The recent C-152 accident on this forum gives a graphic demonstration on the incipient spin condition...
Disagree...no full recovery from the initial Stall. What you think is missing Yaw is expressed in the Nose dropping like a stone. What looks like a "turn" to the right is a fully Stalled and Spinning aircraft. Completely out of control, both wings irrecoverably Stalled. The velocity convinces us the aircraft is in a leisurely very high speed turn. I think no...depending on thrust, completely ballistic...imo
Pitching....Up, tightening the radius. Rolling, Right; Yaw, Right.
"Looks like". But just a ballistic, high speed trajectory, Spin. Not all Spins are vertical, or even (down, steep). One can be climbing steeply, and spinning....
