The device is not for games and requires an approach almost like on a real plane or helicopter. Before departure, everything is checked (the so-called "pre-flight card" in aviation) Even the calculation of the flight zone needs to be examined for trees, power lines, poles and other buildings. Especially important is the height of the return home when the signal is lost. Another point: You love to fly, and someone loves to hunt. So, it's better not to fly over the mansions of the oligarchs))) Yes! do not forget that real helicopters fly at 200-300 meters. It is unlikely that the pilot will notice the quadric.
