and multicopters, which became especially popular in the 21st century. The dream came true to make a virtual flight, to see your city from above, to shoot video from a great height, to enjoy first-hand an unusual panorama, thanks to such a wonderful invention as a quadrocopter.
To learn piloting skills, the beginning of the book covers the basics of designing, operating, and controlling real aircraft, such as airplanes and helicopters. Understanding these basics will help you learn how to control various types of drones..
The characteristics of the most popular quadrocopter models are considered. Useful tips are given for their safe operation in various weather conditions. Much attention is paid to the electronic filling of the quadrocopter for those who are more interested in self-manufacturing, tuning and repair.
Each of the components of a quadrocopter or a drone can be explored and tuned using today’s generally accepted amateur radio tools. The Arduino module, which may become the future flight controller, is also considered..
