This competition was open to any new American glider design that had not been flown at a previous National Championship.

The rules required drawings and stress analysis data to be presented with the completed aircraft.

The intention was that the winning design would be made available as drawings and kits for amateur construction and that Bureau of Air Commerce design approval would be eventually obtained as well.
