Just FYI, I had to slow to about 100 mph, bank over and approach an accelerated stall to see any effect on the tufts... Only the last two rows showed any disturbed airflow. Even at 100 mph indicated and full flaps, all of the tufts were smooth and undisturbed.

Scotty,

The leading edge of your flaps should just be touching the trailing edge of your wing. It looks to me, in the photo, like you have about 60 degrees of flap set.

For the last year I have limited my flap usage to about 35° and have less problems than with 45° of flap setting. I believe that your flap setting in degrees is way to high.
