Northrop Gamma EP 40" ARF

Northrop Gamma EP 40" ARF

The Northrop Gamma was a single-engine all-metal monoplane cargo aircraft designed in the 1930s. Military versions of the Gamma saw combat with Chinese and Spanish Republican Air Forces.


On 2 June 1933 Frank Hawks flew his Gamma 2A "Sky Chief" from Los Angeles to New York in a record 13 hours, 26 minutes, and 15 seconds. In 1935, Howard Hughes improved on this time in his modified Gamma 2G making the west-east transcontinental run in 9 hours, 26 minutes, and 10 seconds.


The most famous Gamma: On 3 January 1935, polar explorer Lincoln Ellsworth and pilot Bernt Balchen became the first people to fly over Antarctica with their Gamma 2B named “Polar Star”.


The RC Gamma

Starting with an idea suggested by Mr. Gerard Harrison, one of our customers, we began designing the RC Gamma in mid-2009. The first prototype was not so good; it flew too fast and was very difficult to control. We made some changes to the wing and control surfaces; the second prototype flew every bit as well as our Gee Bee and H-1. We now proudly offer the Gamma in our series of ‘Golden Age of Aviation’ models. *Special Thanks to Gerard Harrison's contribution on this project.

Servo/pushrod installation note: Position the rudder and elevator servo so their output shafts are toward the rear of the fuselage. Attach the rudder's and elevator's pushrod Z-bend to the rudder and elevator servo's control arm and mount each control arm to its servo. Slide an L-bend keeper onto the rudder and elevator pushrods at the aft-end of the fuselage; make a sharp L-bend in each pushrod where it needs to attach to the rudder's and elevator's control horn; then use the L-bend keepers to secure the pushrods L-bends to their control horns.
