What can I say. Given for a birthday. On the same day I went to test. Went out into the field. Raised 10 meters. The controls are too sensitive. If it flies off at a distance of more than 20 meters, then it begins to slowly respond to control. When leaving the coverage area, it starts singing the song "I'm free" and flies away in an unknown direction. I advise you to fly more carefully on the street and not to raise above 10 meters.
