How to make an Origami fighter jet MiG-21, English version, part 1

Описание: Hello, I am Hiroshi, First Lieutenant "K", a Japanese army (Japan Ground Self-Defense Force) officer in reserve.
Recently I developed an origami MIG-21 fighter jet. The MIG-21 is an outstanding aircraft that was developed by the MiG Design Bureau of the former Soviet Union and first flew in 1955, and more than 10,000 of them have been produced and used in many countries around the world, and some of them are still in service.
In keeping with the Mig-21's "simple structure, easy handling, and moderately high performance" characteristics, I aimed to create a paper plane that was easy to make with paper that could be found anywhere, and that flew reasonably well.
This model is easier than many other works of mine, but still more complicated than traditional Origami planes. Especially the tail area is a little more complicated. Please watch the video carefully and persevere with the challenge.
Compared to the real MiG-21, the horizontal stabilizer of this model is longer in the front and rear to improve stability, and the engine exhaust nozzle is also extended to the rear. Other than that, I think I was able to realistically represent the proportions of the real MiG-21.
For the paper, you can use regular A4 size copy paper. I recommend choosing a thin paper. There is no need to glue the body, but it is a good idea to staple the body in one place. It is not necessary to use a ruler or a measuring tape, as there is no need to measure the dimensions in detail.
This model flies better than the previous F-CK-1 and Mitsubishi F-1, but it is prone to spin due to the large retraction angle of the main wings. For this reason, it is recommended to make the wing tip higher than the root of the main wing when flying. If adjusted properly, the plane will fly about 10 meters or more.
