Culver Cadet (oz16913)

About this Plan

Culver Cadet. Free flight profile scale model for rubber power. Wingspan 12 in.

Quote: "Flying Scale for Beginners. A simplified flying scale model of a Culver Cadet sportplane that can be built ready to fly in less than three hours. By Rex Hall.

OF ALL the sportplanes now gaining popularity the new Culver 41 two-seater rates high in its class. Powered with either a 75 hp Continental or 80 hp Franklin, its performance is exceptional.

Other features are: electric starter, hydraulic brakes and retractable landing gear. Performances obtained by the 80 hp engine are as follows: High speed, 140 mph; climb at sea level, 800 ft. per minute; service ceiling, 17,500 ft.; landing speed, 45 mph
.
To simplify the model and to save the builder time and expense, the Culver has been reproduced in profile form. This does not take away from flying capacity but instead adds to flying hours with minimum repairs. The model is accurate in all respects, except for those usual changes that are vital to good stability. Indeed, the performance of the Culver in model form is characteristic of the original ship.

Construction: Begin by constructing the fuselage. First, the fuselage pattern may be transferred on a piece of 1/16 sheet of hard balsa. Buy wood of a stringy grain; this is usually stronger. When the true fuselage contour has been cut out, lay it down on a flat surface and cut out the sections indicated on the drawing. Sections which have to be cut out are the cabin, wing and motor channel.

Next, the cabin contour may be completed by adding the 1/16 x 3/32 piano wire brace and celluloid windshield pieces, one on each side.

The nose blocks are constructed of 1/4 sheet balsa, placed on each side of the nose, and later cut to the correct contour. The nose plug may be cut from 1/4 sheet balsa, using very hard balsa. The correct nose plug shape is obtained by lightly gluing on a piece of 1/4 sheet balsa. Let this piece dry, then cut the correct contour. Later remove this piece and add a piece of 1/16 sheet to form the rear end of the plug through which the propeller shaft extends. The slot marked A on the drawing may be removed by wrapping a piece of sandpaper around a nail and using it as a rat-tail file.

Make two clips of No.14 size piano wire; these are cemented to each side of the fuselage spanning the motor channel. These braces hold the fuselage in position when the model is fully wound. The propeller shaft is bent to the required size on the drawing, using No. 14 wire. The rear hook is also of No. 14 piano wire; use a little more glue than usual on this when fastening it to the body..."
