Hill Hummer
The Hill Hummer, also known as the Maxair Hummer was an ultralight aircraft developed in the United States in the late 1970s. An extremely minimalist design, the main structural element of the aircraft was a length of 5-inch aluminium irrigation pipe.[1] At one end of this pipe was a seat for a pilot, and at the other, a V-tail. Behind the pilot's seat, an aluminium truss structure supported a fabric parasol wing, which was further braced with wires to another truss element that served as a kingpost above it. The engine was mounted pusher-wise at the rear of the wing truss, the length of the mounting to be selected by the builder to balance the weight of the pilot.
