Jim's Blue Baby AP equipped with small camera that is aimed at the wing. The wing surface is covered with some pieces of string in an attempt to to visualize the airflow over a Kline-Fogelman (KFM) airfoil.
I dont think the string is working though, perhaps you need a row of thread or better yet a silk ribbon tapes along the edge of the foil along the length of the foilabout a inch long this way you can see if the ribbon bends up or down.
But i do see the string moving forward weird
