See http://www.n56ml.com/troy/ for more on gap seals. Just looking at that big honkin' gap that you get when you build the wings per the plans, you can guess that there's an improvement in performance with gap seals. I built my wings with a Frise aileron, and with gap seals on that, I saw no benefit at all to the seals, mainly because the gap seals itself if you do it right. See http://www.n56ml.com/owings.html for more on that (near the bottom). Some folks would think that life is too short to spend this kind of effort on the ailerons, but I thought it was pretty simple and made a lot of sense. I will do my next one the same way, but will likely use a piano hinge at the top for simplicity and drag reductions (eliminating those external hinges from the airstream).
