FPV flight 8 km in the mountains
This video caught the attention of many in the hobby, as the flight shown was at high altitude in the cold mountains. And the very fact of the reliability of a quad capable of withstanding a flight in such conditions really deserves respect. Note that long-range flight requires the pilot not only piloting skills, but also absolute confidence in the components of the drone involved. It is also equally important to know how busy the flight zone is with interference. For example, the author of the video noted that there was practically no interference where he flew. Wind currents are another important aspect that you need to pay attention to before takeoff, because it is known that at different heights the wind currents move at different speeds, which was exactly what the author of the video drew the attention of users to when he reached the maximum distance — 8 km; at an altitude of 2300 m.
For a pre-flight analysis of weather conditions at the launch site, you can use the popular hobby mobile application — UAV Forecast, which provides all the comprehensive data.
