The company was a small Denver airline that wanted to feature the use of its American Gyro Crusader.  The Crusader was a small, futuristic airplane that astonished and amazed the aviation world during the Great Depression. Its magic touched the hearts and minds of all who came to know it, including luminaries like William Randolph Hearst, Jr.; Amelia Earhart; and Howard Hughes. Its rich story ranged from aeronautical inspiration, to courtroom drama and business intrigue. Was it also the victim of industrial espionage and governmental collusion?  The company was unable to raise funds and went bankrupt

After wind tunnel testes, the AG-4 was developed. The American Gyro AG-4 Crusader is an aluminum skined 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.

The prototype was painted copper colored with green leather seats. It was tested in 1935 at Denver Colorado. The aircraft was funded from stock issue 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.
