Between 1910 and 1930, the most popular type of flying model airplanes were twin-pusher A-Frame and T-Frame racers, so named because of the shape of their fuselage or motor sticks. The question is, what was the genesis of that design? Thomas Moy presented a twin-pusher to the Aeronautical Society of Great Britain in 1879, but it is unclear how many would have seen that model. In 1892, however Frederick W. Lanchester (23 Oct 1868 – 8 March 1946), began to study flight. He tested his theories with models and then presented his findings to the Royal Aeronautical Society of Great Britain. In 1908, his book Aerodonetics: Constituting the Second Volume of a Complete Work on Aerial Flight included information and drawings on his models, one of which was his twin-pusher built and flown in 1894.

With his 1908 book, we believe his twin-pusher design would have received attention and possibly be one of the aircraft that influences model design.
Tony Pilmer, librarian at the Royal Aeronautical Society’s National Aerospace Library, Farnborough England, helped by providing measurements and pictures of an original ½ scale model suspended in the library. John Lorbiecki, current President of the National Free Flight Society, helped Museum Director Michal Smith gather more information and then constructed the reproduction. Menominee Tribal Enterprises https://www.mtewood.com/, the business arm of the Menominee Indian Tribe of Wisconsin, was kind enough to donate the white pine used in the model, reported to be approximately 100 to a 125 years old. The completed model was placed on display in July.
