| Subject: | Who's had Flutter? |
It seems to me, on this matter of control surface flutter, that one thing has been
ignored. This list probably has representatives that collectively have an
awful lot of "time in type". Probably the most significant representation of 601
experience in fact. So, from this collective experience I ask, Who has experienced
in flight control surface Flutter??
I did a quick search...didn't see anyone mention or ask for a solution or advice
on how to correct a problem they have had, as usually is the norm on these forums.
I didn't go back to the first post, but far enough to make me think in
has not been problem.
I did see several posted question about control surface balancing...but I saw none
as a solution to an actual experienced problem, but only in the, "do you think
we oughtta" area.
That being said, I have built 5 flying machines and I mass balanced ailerons on
each but one, which was a weedhopper back in 1979...(didn't have em!) simply
because I have always believed this was the proper way to build a control surface,
and having experienced aileron flutter a time or 2 I didn't ever want to
go thru it again. I will confess also that when the stick went wild in my hand
I was operating the craft outside the design envelope. I also will note that
of the other 4 I built..only my current KitFox Speedster came with aileron balance
provisions, the others Did not, and I fabricated my own.
Still I ask....has it been a real problem with any Zenith??? I cannot believe
that the only times it has happened it resulted in a fatal crash,, if in fact
it has ever.
So what say you gents????? IN the experience represented here, how many have had
it happen?

Hi Don;
Have you done it now! You should know that this list is
rarely given to logical thought. All the armchair theorists out there will fill
your mailbox with vitriolic spam.
Do not archive.
