Family gyros (predecessor helicopter) of "Kellet» (Kellet) can trace their ancestry back to the end of 1920-ies, when the brothers Rod and Uolis Kellet began experimenting with the machine K-1H. Having come to the conclusion that their unique concept of using a two-blade rigid rotor (which was more like a rotary wing) is less attractive than the machines of the legendary producer gyros company "Cierva» (Cierva), the company "Kellet" abandoned "flying wing" and enable set its four-bladed machines Conventional hinge screw.

By mid-1930-ies the company has advanced so much in the way of creating a gyroplane that modifications to vehicles 20-2 / -3 were sold to civil and military customers. The appearance in the middle of 1930-ies gyroplane KD-1 attracted the attention of the US Army and Air Force decided that it is necessary to evaluate the possibility of the gyro military applications. In 1936 year for the needs of the US Air Force had purchased a gyroplane KD-1, received designation YG- 1. The following year was bought seven cars YG-1B, which differed from the first gyroplane additional radio equipment and a reduced supply of fuel.

Five of the seven gyros YG-1B were included in a standard training program for artillery spotters and used as connected aircraft, while the other two were returned to the company "Kellet" for further improvements. After extensive testing pilots US Air Force stated in the report that the gyro YG-1B does not have many advantages over the aircraft at the time, equipped with fixed wing, and the gyros were transferred to the US Border Guard in Texas.
