Post 3069 - Leightman 957
In the early 80's I believe NASA did some testing of deep stall characteristics using a single place T tail Schweitzer 1-36 which was modified to permit the horizontal stab to angle nose down to about 45 degrees. The pictures of tell tail streamers angled up about 45 degrees to the wing mean chord in a steady stable descent was arresting.
