Various paper airplane folding tutorials

Various paper airplane folding tutorials are as follows:

Step 1: Use one-half or one-quarter of a rectangular piece of paper or A4 paper to fold its two long sides in half before unfolding, leaving creases.

Step 2: Fold the two corners of a short side to the opposite side, align the short side with the long side, and unfold to leave a crease.

The third step: turn it over, that is, turn this short side up along the intersection of creases, and then unfold it to leave creases.

Step 4, turn it over again, and fold the rice-shaped side into a double triangle according to the crease.

Step 5, the left and right bottom corners of the triangle on the surface are respectively folded to the top corners of the bottom surface to form two isosceles triangles.

Step 6: Fold the outer four waists of the two isosceles triangles to the middle bottom respectively, and then unfold them to leave creases.

Step 7: Knead two isosceles triangles into the shape on the drawing along the crease inside.

Step 8: Fold the lower corner back along two vertical angles, as shown in the figure.

Step 9: Fold both sides from the front along the middle crease.

Step 10: Fold the upper and lower parts of the left side to the right along the left vertex angle of the lower triangle.

Step 1 1: Fold the upper and lower parts of the right side to the left by about 1 cm respectively.

Step 12: unfold the overlapping parts by about 90 degrees respectively, and slightly adjust the wings of the aircraft to fold an aircraft that can fly and hover for a long time. The operation is simple, just pay attention to the closing direction in step 9.
