The Sunseed is a rigid-wing model developed by Bob Trampenau in the 1970s. Bob later went on to form Seedwings and produce the successful line of Sensor hang gliders. The Sunseed had a unique "seagull" shaped wing shape, with dihedral in the inner half of the wing and anhedral in the outer half. Plans were sold for this glider, at $50 each.
I'm looking for more information on this model.
