Wow, hope this isn't common!

At a speed where the engine is out and not over revving? That's not flutter, that's wiggling the controls...

You've got to be kidding.

If you want to see real flutter, take a look at this:

Well spotted. Its clear from the video that the flaps are in landing
setting during the initial part of the flypast. You can see them clearly
during the initial approach and the fact that the wings are almost
straight is another clue. Watch the next ASH-25 approach and landing when
you're at the field and you can easily see the usual curve in the wings
flatten out as landing flap is selected and the mixer moves the ailerons
to a negative setting.
