Comment:
Nelson developed the Hummingbird in 1953 after discontinuing the Dragonfly. It is a two-place tandem self-launching sailplane. The Nelson engine retracts when not in use, cutting drag for soaring. The fixed gear is two wheels in tandem, the front one steerable with rudder pedals. It features an all-moving horizontal tail with anti-balance tab, spoilers and dive brakes, and styrofoam-filled leading edges. The original version, of which two were built, was almost all wood; later models were metal. Two belongs to the National Soaring Museum, and one belongs to the Smitsonian Air & Space Museum, Washington.
