Contest Model Glider. Free flight towline glider model.

Quote: "Build this Contest Model Glider. Building is simplicity itself if you follow our step by step instructions.

Quite apart from the fascination of making this type of model, flying the finished aircraft will give hours of enjoyment. It has been so designed that when is launched from a long nylon tow-line it will take advattage of rising currents of warm air - 'thermals' to use gliding jargon - and fly for severed minutes in soaring flight. In fact it is an excellent model for entry in many national model flying rallies organised up and down the country during the spring and summer months.

Scaling up Drawing: First draw out full size the shape of the fuselage in side view end top view (see Fig.10). Draw accurate 1 inch squares on a piece of cartridge paper or buy a large piece of graph paper which is already divided. Pin this down to a flat board and plot the outside shape of the fuselage side view and top view, using the squared drawing opposite as a guide.

Mark the points where the fuselage curves (which are the same on each side and top and bottom) cut the vertical and horizontal lines of the various squares. Join up the points with a smooth continuous line, using a piece of springy wood.

Mark the thickness of the fuselage outside strips (1/8 in) and draw in the lines. Follow this by drawing vertical parallel lines 1/8 in apart to represent the spacers positioned as indicated. At the junction of spacers with outside strips rub the drawing with a candle to prevent the eventual cement joints from tearing the paper.

Building the Fuselage: At alternate intervals of about 1-1/2 in push straight pins into the lines representing the fuselage outside strips, and between them slide strips of 1/8 square hard balsa (Fig.1). Now cut off the various spacers to length and at the correct angles at their ends, and fix them in place with balsa cement.

Build a second side in exactly the same way directly on top of the first but place pieces of wax paper between the trwo frames (Fig.2). Cut protruding ends and separate the frames. Mark shape of nose panels (Fig.3) on 1/8 sheet balsa, cut them out and cement in place flush with the outsides of the frames..."
