I was looking for a different video, the one I was looking for was a Hawk or L-39 flying over a frozen lake that does a slow fly-by them tip stalls on the pull out.

Here is another one though that does an accelerated stall on a bank (same thing my plane did)

I am sorry that my (and most everyone else's) opinion (as they are all opinions) do not match up with yours. I don't know why you would say the flaps are moving up and down rather than saying the sun angle was making it appear as though they were moving. If the flap movements were "intermittent," the plane would have shown different flight characteristics at other portion in the video, not just when the plane finally entered an unrecoverable accelerated stall.

Just my uneducated .02
