Randy,
Count me in Robert's corner on this - exceed VNE at
your own peril, but please don't do it with unwitting passengers
onboard.
I've seen too many films in the military of what
happens to airplanes when flutter begins at excessive airspeed. It's
not something you feel coming on like stall buffet and recover
from. It can tear an airframe apart in the blink of an eye. Sure,
differently built planes will experience flutter onset at differing
airspeeds, but why would any sane person intentionally exceed a limitation set
by the plane's (or kit's) manufacturer? In the absence of a detailed set
of data, including testing an airframe to failure in a wind tunnel, that
limitation is all you have. Sure, it likely has a buffer built into it,
but intentional ignorance of the redline on the ASI in any
airplane that wasn't specifically designed and modified to do it,
experimental or not, is a bad idea.
