Thanks for the reference to the RV article on flutter.I know some are
interested in pushing the envelope and this is an excellent discription of
the aerodynamics involved.Some KR accidents in the past have had these
factors at play but the facts of those were lost when the pilots were
lost.We don't
d be easily found via a
Google search.

Best regards,

Jeff; small correction- 190 IAS is aerodynamically equal to 190 TAS @ standard
I should add the caveat that I have no cables in my elevator controls.
Strictly a push rod configuration.

Jeff; I've read the article and am very concerned. I'm a CFI so what I teach
determines pilot's behavior in practice. I want to read more before answering,
but I have four observations: 1. The Mooney turbocharged models do not vary Vne
(IAS) with altitude. 2. sailplane manufacturers lower Vne wi
Jeff; small correction- 190 IAS is aerodynamically equal to 190 TAS @ standard
conditions. Your pitot reacts to the dynamic pressure of impacting air
molecules, independent of density altitude, just like your flight surfaces
will, so flight testing to 215 IAS has been demonstrated without flut

The design does not require any balance weights on the elevator, just the
ailerons.
