Introduction 1935

The American Gyro AG-4 Crusader is a small twin engine aircraft. The aircraft was designed as the Shelton Flying Wing in 1933 by Thomas Miles Shelton.[1]

Design

The AG-4 was developed using wind tunnel tests. The American Gyro AG-4 Crusader is an aluminum skinned four place low-wing twin engine aircraft with fixed conventional landing gear, twin tail booms with individual rudders, and a teardrop shaped fuselage. The wing uses trailing edge flaps and 25 gallon fuel tanks are mounted in each wing root. Retractable landing gear were also tested on the model.[2]

Operational history

The prototype was painted a copper color with green leather seats. It was tested in 1935 at Denver Colorado.[3] The aircraft was funded from stock issued in the Crusader Aircraft Corporation, a parent of the American Gyro Company. The company folded in 1938 under securities fraud investigations before the Crusader could go into production[4]

Tootsietoy came out with a die-cast metal toy of the plane, No. 719 in its catalogue.[5] Hubley and Wyandotte also made toys based on the Shelton Flying Wing.
