Sperry-Messenger model airplane plan



The Sperry Messenger was an American single-seat biplane designed by Alfred V. Verville working for the Engineering Division of the United States Army Air Service (USAAS) and built under contract by Sperry Aircraft Company of Farmingdale, New York. The aircraft was later designated the M-1 and MAT by the USAAS. Sperry produced approximately 50 Messengers and the civilian two-seat version, the Sport Plane, between 1920 and 1926. Lawrence Sperry gained national attention when he landed his personal Messenger in front of the Capitol building and bounced up the front steps in Washington D.C. (See photos ) He also successfully landed his little Messenger at the Lincoln Memorial.

The plans take some studying to determine how to proceed with the construction of this model airplane. In the left lower part of the plan are 2 long strips one of which is labeled as a strut. Both of these are struts going from the bottom of the fuselage to the attach point on the wings. Superimposed upon the wing plan or 3 parts labeled "CS" – these are the form shapes for the cabane struts. It's worrisome to me that the landing gear struts are one 32nd balsa. I suppose landings aren't part of the program in this model. Other than these few points this should be an airplane that would take a couple of evenings of steady work to build it, complete it, then fly it. Hopefully the model builder/flyer won't be landing on any buildings front porch! (Joke!)

You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling. To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.

We can scale the Sperry-Messenger plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.
