As I went hiking in the mountains, I realized I needed a drone. Weight and the ability to get power from a PowerBank are two factors that should be considered here. The power bank has a capacity of 20,000 mah and weighs approximately 0.35 kg. It can charge three to four batteries simultaneously. On a journey that lasted for a total of eight days, the total capacity was 50,000 mah, and each day I flew with one to two batteries. I flew in conditions that included light snow, moderate wind, and temperatures as low as -5 degrees Celsius. The remote control refused to charge. The maximum height at which you can take off is 3,000 meters, and everything is functioning normally. Although it has several nice capabilities for rapid shooting, it does not have an active track for shooting while moving. In the high-speed mode, it is not impossible to keep up with the car while it is traveling at a speed of fifty kilometers per hour. There is no communication between the remote and the device. I did not fly more than 2.5 kilometers, but in my experience, difficulties typically start to manifest themselves at lesser distances. I would like to be able to control the drone using the DJI GO4 app. That app allows you to adjust various aspects of the controls, such as how smoothly the sticks move. In general, I couldn't be happier with this purchase (a drone that you can always take with you and will want to take with you).
