Scotty, The leading edge of your flaps should just be touching the trailing=20 edge of your wing. It looks to me, in the photo, like you have about 60=20= degrees of flap set. For the last year I have limited my flap usage to about 35=B0 and have=20= less problems than with 45=B0 of flap setting. I believe that your flap=20= setting in degrees is way to high. -- Lorn H.
