1. Cut the calendar paper (or other similar paper) and stick the two ends to each other with glue to form a circular wing.

2. Cut and process the single-layer blow molded paper (or thin cardboard) to make horizontal wings and vertical wings.

3. Body production: Take a 250 mm long paulownia wood strip, first draw the outline of the fuselage on the paulownia wood strip, and then use a sharp knife to cut off the excess part.

4. Assembling the whole machine: First, glue the horizontal tail on the end plane of the fuselage. When bonding, pay attention to the left and right symmetry of the horizontal tail and keep it perpendicular to the side of the fuselage. After the vertical tail is firmly glued, the wings can be installed.

5. Use a 90 mm long Paulownia strip to clamp the wing to the fuselage. Use a rubber band to tie the Paulownia strip to the fuselage firmly. The bonding point of the wing should coincide with the center line of the wing. , so that the rings on the left and right sides of the wing are equal in size and consistent in shape. In order to make the wing have a stable dihedral angle, after the rubber band has fixed the wing, apply a little glue on both sides of the Paulownia strips, and glue the roots of the upper wing surface and the sides of the Paulownia strips to each other firmly.

6. Trial flight adjustment: After the model aircraft is thrown, the attitude of the aircraft is nose down. This is the reason why the nose is too heavy. You can move the wings appropriately toward the nose. If the aircraft trajectory is wavy, the nose is too light and the wings can be moved backward. If the aircraft's trajectory is not straight and always flies in a circle, you can check whether the left and right wings are consistent and adjust them; or adjust the flight direction by adjusting the rudder (vertical tail).
