This is a modification of my original review. To illustrate this, a test of the zuhafa T4 drone. This drone is a foldable drone that comes with a soft case and two cases, making it easy to store and carry, with a total flight time of around 40 minutes. There are no extra batteries. This drone supports Altitude Hold, so it will automatically take off at around five feet and land automatically unless you want to make a bumpy landing with the joystick. The ability to levitate in place is said to be achieved with a downward-facing stationary camera, but this is sketchy at best. I'm an experienced drone pilot and this drone spins out of control and crashes about 3 times out of 5 if you expect it to hold position in an enclosed space. the horizontal hold function also promotes jumping in level flight. When you release the joystick it will return to the center position and the drone will start rocking back and forth before hopefully landing. There are three speed settings. When hovering correctly, the drone is calm and stable. There is no built-in SD card, so all images and videos are dependent on the app and mobile phone. This can and will introduce a limit of around 100ft for images, video and fpv/vr functions. In other words, you're not going to fly this thing at high altitude, relying on photos and videos. I had video lag. This is typical for all drones with this setting. A separate remote control enables training/flying without internet or mobile phone. The application is complex and the manual does not cover it comprehensively. The manual mentions that some features aren't available for some models, but doesn't specify which ones. Apparently none of the offline features advertised as available with my T4 are applicable as none of them work. In leading mode, it identifies and outlines objects but does not follow them. That's disappointing considering this is what I would call a selfie drone. With range and altitude limitations for photos and videos, and a harrowing flight, this is definitely not a sports or high-altitude photography drone. The app lets you do some cool things like: B. switching from the front-facing camera to the bottom-facing camera, although the resolution of the bottom camera is noticeably lower. In summary, I've spent a lot of time loving this drone and finding a niche for it in my collection. Until this happened.
