I wonder over the years and to how many modelers, flutter has claimed aircraft?

There's a video on U-Tube showing a jet turbine smashing and exploding into a treeline. When the video slows down, you can see the flying surfaces flapping up and down like some mad bird just before impact.

I think vibration is another factor. Some of these ARF's are built so light and with such minimal structural integrity that they have to "resonate" while flying. Add more muscle up front and I believe the situation increases expotentionally.

Anyway however you evaluate it, losing one's airplane for any reason, (including pilot error) is never a fun thing.
