I have been using it since February 2022, I have flown a little, only 6 hours, but I can say that I tested the drone in very different conditions. Launched in sub-zero temperatures in the Urals, launched at an altitude of 2400 above sea level, launched in gorges and caves. There were only 2 troubles. The first and main one was a sudden loss of altitude without any prerequisites. The weather conditions are flying, descending air currents were not noticed either by the own sensations of dozens of people who were present in the vicinity of the drone, or by the foliage on the trees in the filmed video. But nevertheless, with a charge of about 40%, the sport mode, the maximum stick raised up, the drone rapidly lost altitude -1.5-3.5 m / s for several seconds in a row, as a result, the drone crashed to the ground through the crown of a tree. I was insanely lucky, the device did not receive any damage, it flew a few more hours after the incident, everything is OK. We are looking for reasons together with support, then I will supplement the review with a response from support. I found a similar case on YouTube, only there a man lost a drone in the sea. The second trouble arose in the gorge, where GPS satellites were visible with varying degrees of success. In such conditions, the climb limitation of 2-3 m is triggered, and it turns out that by lowering the drone into the same gorge, with insufficient signal reception from satellites and with a concomitant change in atmospheric pressure, you risk not raising it to the height of the take-off point. Otherwise, it's a good device. Take without hesitation. In 2022, there is no better proposal for the ratio of all characteristics yet.
