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. |
