Not sure I my markings are dark enough, but I posted some photos of my recent flap design. Question: is the gap up top large enough to provide sufficient flow over the top of the flap? I notice that other designs have an inch or greater at full deflection, I assume lowering the hinge point would bring the flap further back, creating a Fowler effect, but would create a larger gap. First photo is flaps up, second is at 50 degrees the half circle is 3/8 inch around my planned trailing edge of the wing. The line at the nose of the extended flap is 1.5% above the chord of the wing. Any input will be greatly appreciated. Maybe I'm off track, but at least I'm still on a hinge.
