the glider is designed from 1pc. The front part has 80% padding as weight. The rest of the model is then filled with 15%. the plane must first be assembled. Bend the rear wings by 90°, bend the front wings by approx. 45°. If necessary and for better stability in the air, it is possible to bend the surfaces at the end of the wings in the front and back. the plane has to fit really hard to fly far. In the photos you can see how to hold the plane during the throw so that it flies really far
