  • Patent number: 6290179
    Abstract: A scale model airplane kite made of STYROFOAM, an expanded rigid polystyrene plastic foam, and having reinforcing members, rods, dowels, pegs, pins, skewers, or the like embedded in the foam at stress points and oriented to counteract stress forces. These kites are lightweight and can withstand a 15 mph wind. The kites are easy to repair by using more pegs and glue at the fracture site. These kites have string attachment or tether holes reinforced with a plastic tube and balsa wood to prevent the string from coming through the foam and allow the flyer to adjust for different wind velocities. In accordance with one embodiment, the kite is formed of half-inch thick bead foam which is substantially rectangular in cross-section and is cut in elevation and plan view to scale of an actual airplane or aircraft such as a P-40, Zero, P-38, ME-109, FW190, DRI Folker triplane, and the like. Also, the foam may be painted and plastic tails may be added to enhance the aesthetics thereof.
