The framework, or fuselage (A), connecting the planes, is a cardboard strip of the dimensions shown in Fig. 480, folded where indicated by dotted lines, into the shape shown in Fig. 481.

Main plane B and elevator plane C are pieces of cardboard of the size shown in Figs. 482 and 483. Cut a notch at the center of each of the long edges of each plane as shown. The planes must be centered on the fuselage. Cut slots in the fuselage strip, as indicated, to slip the planes though, and when you find by testing out the glider that the ends of the planes balance fix the planes in position with pins run through from the underside of the fuselage (Fig. 481).
In launching the model, turn it so that elevator plane C is in front. The advantage in making the glider type of model air-plane is that it requires neither motor nor propellers, which are the most difficult parts of model airplanes to make.
The glider will not go a great distance, but if you will shoot it into the air by means of a rubber-band slingshot you
can send it several hundred feet.
