You could probably say that about almost any small airplane, really...


Are you saying the BD-5 will not recovery from a spin?

With the original wings, the BD-5 has good spin recovery. With the GAW
wings, you stand a good chance of an unrecoverable flat spin. It's been
talked about on the mailing list by people who experienced this many years
ago, and is the reason most people don't build the BD-5 with GAW wings. The
airfoil Harry Riblett suggested for the BD-5 has given good results to those
who have used them. Mine has that airfoil, but not as a reprofile -- the
original build made new ribs as part of the redesign of the wing with a
conventional spar. I'll let you know the results when it flies.

More info on this is available here http://www.bd5.com/bulletin.htm. The
last two published editions of the Bulletin (I only did a few after I took
it over, and discontinued them when the site and mailing list became fully
operational) have two articles reprinted from EAA's Sport Aviation magazine
written by the late Seth Anderson, who owned a BD-5 which he converted to
turboprop and modified in many other ways. It has a good analysis of the
flight characteristics of the BD-5. There's also a flight test report from
the late Les Berven, who was Bede's original test pilot on the BD-5 program,
here http://www.bd5.com/testberven.htm but it does not go into spin testing.
