Big flexible surfaces can flutter all by themselves *as shown in that
clip of the A6 I posted and that might be what you mean about the Cl CG

engine is a good idea and why the pods on jet airliners (which have the
structural rigidity of Jel-lo) are mounted out in front. The change in
CG helps dampen the flutter in the same way as mass balance on an
aileron would.

Bertie, What are you trying to do here? Do you realize that your
respectful aviation related post will ruin this list for guys like Jay
and his petty abusive OT posts ?
