Ladies and Gentlemen:
Wing flutter, aileron flutter or whatever -- if any of us experiences this
phenomenon, what is the corrective action? I understand that we have a
minimal amount of time!

The answer is almost always reduce speed.

Gig,
Thanks for the reply! Your point makes sense! Let's discuss this further. In reducing speed, one should pull back on the throttle, but should one ease the nose up as well? What have others done that experienced flutter and are still here to talk about it?

I've never experienced flutter though I have hit turbulence when I was above the maneuvering speed of the aircraft. In both cases you don't want to increase the G forces on the aircraft especially the wings. As draggy as the 601 is pulling the throttle ought to reduce speed quickly enough that a nose up isn't needed. To a certain extend this should be true in any aircraft because as long as you are reacting very shortly after the onset of the flutter the power reduction ought to get you back below the flutter threshold in a timely fashion.

GIG.
Good point to consider. Flutter, especially the divergent\unstable type, may
continue well below the speed at which it started and stopping it quickly is
paramount.
Anyone looking for more info should Google "Aerodynamic Flutter".
