I se that the RG15 profile is used on some of the model intended for F3B an F3J. I was of the impression that the profile was primarily a speed airfoil so how does it cope with the "hanging" parts in competition? The SD7037 is the most common profile used, is this "much" better than a RG15 wing with camber change dialled in? -- Regards Erik Wikran Tromso, Norway --------------- RCSE-List facilities provided by Model Airplane News.
