I. Methodology 1

1. Prepare a piece of A4 paper (other waste paper is also acceptable), then align the two sides, fold it in half, and then loosen it.

2. Fold the corners of both sides to the middle straight line along the middle broken line, and the edges coincide with the middle broken line.

3. Turn the folding surface over and fold it in half, then fold it along the hypotenuse to make it coincide with the middle folding line.

4. Continue the above actions, then fold the bevel edge to make it coincide with the middle fold line, and finally unfold the outermost side to fold the paper plane.

Second, the second method

1, first prepare a rectangular piece of paper.

2. Fold the center line in half and unfold it.

3. Align the center line and fold two corners.

4. Turn the paper over, aim the vertex of the triangle at the center line, continue the previous step and lift two corners.

5. Fold the extra corners and fix them.

6. Flip in half and lift both sides.

7. A simple paper plane is ready!

Three. Method 3

1. Tile the paper and fold it so that the top and left sides of the paper overlap. Please note that the edges must be aligned. Collins suggested flattening the paper with a ruler or broken bones to make the creases more obvious.

2. Tile the paper, according to the method in the first step, overlap the top and the right, and fold it again.

3. Lay the paper flat and fold it so that its right side is parallel to the diagonal crease obtained from the upper left corner in the previous step. However, in order to prevent these edges from mixing when the plane is folded, the distance from the right to the diagonal should be1mm.

4. Fold down the vertex so that the top and bottom of the paper are aligned, and the paper should be as flat as possible.

5. Fold the vertex in the upper left corner and the vertex in the upper right corner to the middle along the long creases on both sides. Then expand the two top corners and fold them according to the original method, and the vertices of the two top corners will coincide in the center of the paper.

6. Before the tail is formed at the top, fold the plane along the center line to form the nose. When you are satisfied with the alignment of all the edges and creases of the plane, you can flatten the paper again to make all the edges and creases more obvious.

7. Fold the paper into a wing at a distance of 3 mm from the nose of the plane. You can use your thumb to fold the paper in the right place. The long side of the wing should be aligned with the upper right corner of the bottom, not with the bottom line. Do the same thing to the other half of the plane. Flatten creases and nose.

8. Clamp the aircraft head to fix the aircraft, and fix the aircraft with 30 mm wide transparent tape. Cut off two pieces of 2 mm long adhesive tapes and fix the right-angled edges under the fender respectively. Then cut 3 mm tape to fix the fuselage and the nose together. Cut 2 mm long adhesive tape, cut it into two pieces, and fix the wing under the plane.

9. Cut off a piece of tape and fix the upper and lower parts of the tail respectively. Then flatten the tape. Make angles of 155 and 165 on both sides of the card respectively. This can be used to measure the angle of the paper plane. The back of the plane should be 165, and the nose should be 155, which is more in line with aerodynamic requirements.

10. After checking the wing angle, cut the last section of tape into two sections, one section is stuck at the nose and the other section is stuck at 10 mm behind the nose. Such a paper plane that can fly far away is completed. Find a place with good air conditions for test flight!
