The Woopy-Fly, a sort of paraglider/trike/ultralight hybrid shown on the world stage at AERO Friedrichshafen this April 2010 in Germany, has a wing that folds for storage like a paraglider - because it's inflatable. Currently, it appears the wing itself is only available from distributors in Switzerland, Russia, and Japan. Those wishing to buy the trike (plus wing) can expect a complete kit cost to run about 13,780 Swiss Francs, which currently is about US$12,400 - plus the legal disclaimer that releases the manufacturer of liability.
