I can't see Airbus refusing such an oppertunity to share and adopt my simple invention without any silly modifications. The hardest part would be drilling holes in the plane for the the lowering string and hinge screws, connecting up to the controls a piece of cake. I used to build and fligh control line model planes and the stick trick worked very well. A chap here has an electric powered radio controlled plane, ready built of course with whom I've begged to install the system on it but he doesn't seem too keen. Sticks of wood are available everywhere. Wickes, Homebase, cut from tree's, nicked from fences. it doesn't need any further development which might impair it's simplicity and performance. Of course a few shares can be yours if you pull your weight in the enterprize.
