Robert, Given that a Coupe already will not stall or spin, I cannot really see how vortex generators could contribute anything useful.
BUT I'd bet they could really dangerously screw up the sweet handling characteristics. REASON The Coupe non-stalling design is based on a precisely calculated progressive stall pattern that starts at the fuselage and spreads outward. Before it can get anywhere near the wing-tips the wing center loses lift, the nose stops rising, the entire plane descends in a flat attitude, and the progressive stall is halted and reversed. If we mess with those precise wing characteristics, my bet is that the coupe would lose its "characteristic" inability to stall or spin. I am not being the least bit flippant when I say that the Coupe already has perfection, in this respect, and any tampering with it would throw away that perfection with likely fatal results. In short, NOTHING TO GAIN, EVERYTHING TO LOSE. (As my assistant wisely comments when he notices my wife applying cosmetics, "Make-up is for the OTHER ladies. Forget it. You CANNOT improve upon perfection.") Whatcha think?

They are reported to improve the low speed handling of other type aircraft esp-ecially on short field landings and takeoffs and I was wondering if thy would be of any benefit to our coupes. Any input would be appreciated Bob 1966 Alon A2 N5621F Maryland Robert Bullock Regional Sales Manager ERECT-A-TUBE INC 800-929-2666 Office 301-748-1402 Cell 301-829-3522 Fax bullock...@aol. <mailto:bullockbob%40aol.com> com
