Sorry about those pilot photos, my cell phone takes lousy pictures. Decided to put in the three leading edge wing tip air flow slots. Made up a 5” long box using 1/4” square and sheet stock. Cut into the wing in the appropriate area and slid the box in. Will razor plane off the excess the put some tape on the wing around the slots and sand it down flush with the wing. The slots will then get some further work to duplicate the shape of the slots on the top and bottom of the wing. I’m curious if putting these in will have any effect on the planes flying.
