I needed a drone for trekking in the mountains. Here, of course, weight and the ability to charge from PowerBank are important. The combo kit weighs only 1.3 kg, PowerBank at 20,000mah is about 0.35 kg and charges 3-4 batteries. For a trip of 8 days it was 50,000mah in total, I flew 1-2 batteries every day. The remote control never charged - very tenacious) I flew in light snow, moderate wind and temperatures down to -5. The maximum take-off height is 3000m, everything works fine. Nice fast shooting features, but lacks an active track for shooting on the move. In high-speed mode, it is quite possible to follow the car at a speed of 50 km / h. Communication with the remote is nothing. I did not fly further than 2.5 km, but more often problems begin to arise at shorter distances. I would like to be able to control the drone in the DJI GO4 app - there you can adjust the smoothness of the sticks, etc. In general, I am very satisfied, a drone that you can always and want to take with you)
