Out of curiosity I made a test. I built a cuff with an 21/2 ft arrow
shaft attached, line up with the wing chord. I had several strings
attached on top of each other about half inch apart and different
length. Very interesting to see how the air responds well ahead of the
leading edge but useless for any useable information. With flaps, the
changes I was interested in were to small in any case.

I was Googling around, and ran across yet another AOA device. Check
out this site:http://www.adventureairsports.com/aoa.htm
and pay particular attention to the 3rd photograph. Yaw string and AOA
in one, and not very expensive!

I think it's likely that the SafeFlight vane-type AOA indicator works fine
as long as you are fairly good at keeping the yaw string centered.
SafeFlight has been around selling these things to airplane owners for a
long time. It's nice to see them offering a product for gliders.- Hide quoted text -
