The Northrop Gamma was a single-engine all-metal monoplane designed in the 1930s, with many variants that shared then-innovations such as wing fillets, aerodynamic spats covering its fixed landing gear, and a fully enclosed cockpit.

Initially serving as a rugged civilian transport, the Gamma was used as a mail plane by Trans World Airlines, and later military versions served mainly as light bombers for the US, Chinese and Spanish Republican air forces.

In June 1933 a Gamma 2A "Sky Chief" was flown by Frank Hawks from Los Angeles to New York in a record 13 hours, 26 minutes, and 15 seconds. Not to be outdone, in 1935 Howard Hughes used his modified Gamma 2G to set a new record of 9 hours, 26 minutes, and 10 seconds.

The most famous Gamma was probably the "Polar Star," used by polar explorer Lincoln Ellsworth and pilot Bernt Balchen who became the first people to fly over Antarctica on January 3, 1935. In November 1935 this same Gamma was again selected as Ellsworth and Canadian pilot Herbert Hollick-Kenyon used it to attempt the world's first trans-Antarctic flight from Dundee Island in the Weddell Sea to Little America; however, after flying more than 2,400 miles and getting to within 25 miles of their goal, on December 5, 1936 the "Polar Star" ran out of fuel! Ellsworth and Hollick-Kenyon managed to survive in the abandoned Richard E. Byrd camp, and they were rescued on January 15, 1936 by the crew of the research vessel "Discovery II." The abandoned "Polar Star" was eventually recovered, and it was donated to the Smithsonian National Air and Space Museum, where it resides to this day.

Maxford USA's ARF version of the Northrop Gamma began as an idea suggested by one of our valued customers, Mr. Gerard Harrison. Design work began in mid-2009, but the first prototype flew too fast and was very difficult to control. After changes to the wing and control surfaces, Maxford USA's second Gamma flew every bit as well as Maxford USA's popular "Golden Age of Aviation" models of the Gee Bee and Hughes H-1.

We invite you to enjoy the pride of ownership and the joy of flying your high-quality balsa and light-ply almost-ready-to-fly version of this historic aircraft.
