Ailerons on the rotor-blade tips control direction of a one-man helicopter built by Fred Landgraf of Los Angeles, California. Nicknamed the "Flying Easter Egg" because of its shape, the 850-pound craft has a retractable gear that can stand the shock of power-off emergency landings. An 85-horsepower engine turns its two overlapping, synchronized rotors at a top speed of 100 miles an hour.
