|Hang Glider Weekly was publisher of some key facts on the innovative company Seedwings with founder, designer, inventor Bob Trampenau. We have strong reason to look to roots of VG --variable geometry-- in Seedwings. The company's Sensor's fiberglass curved wing tips and the enclosed cross bar were invented by Trampenau and first flown in 1976 and shown in Hang Glider Weekly. He further invented wire braced washout struts in 1978 now used on all topless hang gliders and the wrap-around Mylar leading edge pocket in 1979 all before the UP Comet. Trampenau continued inventing; and he first HGMA certified the curved wing tip, enclosed cross bar, and an all-wire trailing edge reflex bridle stability system and VG. The wire-braced washout struts and wire-reflex bridles are the two most important stability safety features on today's hang gliders. Another safety-and performance-feature that is significant are the flaps on a hang glider. Seedwings owner Bob Trampenau invented the current flap system in 1992, and as yet no one has copied it. The Seedwings trademark is internationally operated out of the headquarters in California.|
