Absolutely, tho 'fwapping' might be a better description. My CMR Manta made the same sound before it 'exceeded the speed of balsa' on a B6-2.

I think that particular Canard is prone to flutter / "fwapping", due to its high aspect ratio design.

Using "Balsa Plywood" should cure that problem, since it would be stiffer and resist flexing during boost.
