Now that you are reading this, I will add a few more points.
1- This aircraft is made in Android and has a harder control on the computer, especially the up and down movement, which is set to 180 degrees. (If you play on a personal computer, it is better to despise it)
2- The fuselage of the plane is deliberately made of glass with reflection -100 to shine at night.
3. When sharing an airplane, the glass is displayed as you see it, making it difficult to detect.
4- Betz, please tell me how to open the exported file on simple planes.
