Spinning-wing Autogiro.

It's a model plane with a spinning wing, or rotor, that windmills in the slip stream of a conventional propeller to provide the lift necessary for flight.
The rotor is self-spinning and that's where the autogiro or gyroplane, as it is now called, differs from the airplane and helicopter in appearance, in flying characteristics and also in construction.

Three pages ( 2 sheets - front and back on first sheet and front on other sheet ) B & W photos, illustrations, expanded view and instructional narrative.

My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
