Thanks for pointing out the Pipestrel manual. It is superb and is
much better than any aircraft manual I have ever seen. Yes it has an
excellent discussion of flutter and Pipestrel's experience when 2
pilots exceeded VNE. This manual should be compulsory reading for all
aircraft and glider pilots and, of course, for all glider
manufacturers so that they can improve their manuals. This is the kind
of info I have been searching for.

I disagree. This extremely verbose chatter is *not* what I want to read
in a manual. All I want to see is a table with the speed limits at
several altitudes, like e.g. on page 2.3 (below) of
http://www.dg-flugzeugbau.de/Data/Ma...gh-1000s-e.pdf

The background for this is basic aviation knowledge which hopefully
every pilot has learned and understood. I don't want to have to sift
through this stuff over and over again each time I look up a number in a
manual.
