Winnie Mae (oz8173)

About this Plan

Winnie Mae. Radio control scale model. For .60 power. Uses a floam planked wing. Scale is 1/6.

Note the plan was printed in the magazine with text: "Plan available in either 2in=1ft as shown or 1-1/2in = 1ft. Smaller version may be more suitable for sport/scale flying."

Quote: "Today, the Winnie Mae, in her final high-altitude configuration, is on display at the National Air Museum, Washington DC, where she's been since 1935. Construction : This configuration of the Winnie Mae is based on her appearance after conversion to a 5C following an accident.

Everything aft of the CG should be as light as possible. About a pound of ballast had to be added directly under the engine to bring the CG within the limits marked on the plans. A Supertigre 71 with a Perry carburetor was used but a good 60 would be adequate.

Some of the building techniques may be questioned, but decisions were based strictly on keeping to scale.

Photography was used to gather data, to help scale up factory drawings, to produce an almost scale instrument panel, to check appearance during construction, and to make a movie record of the test flight for performance analysis.

Wing: Foam planked with 1/16in sheeting was used. The locations of scale ribs and spars are indicated for building it up. The root rib is a Clark Y 18 and, to finish lofting, an imaginary rib positioned at the tip is a Clark Y 9.47..."
