We bought a UAV on the spur of the moment recently. This was not an ideal experience, but it taught me some lessons. What do I want? A good flight experience starts with GPS and stability control, or gravity sensors. Good camera and image stability are also very suitable for those interesting photos. This is not necessary, but if you have a low quality camera and try to take videos or photos, the photos will become grainy. In addition, for photos, I want the SD/TF card slot on the UAV. If there is no on-board storage, the images must be returned to the phone, which reduces the quality (usually). Brushless motor is a huge advantage. They look a little quiet, but the most important thing is that they are speed controlled and can control the motor more accurately. In previous UAVs, I often encountered many problems with different motor power. Anyway, after reading the comments and articles for several days, I bought it and it did what it said. Since the first takeoff, the UAV has been as firm as a rock. It's really amazing. The control is simple. The video screen provides clear and smooth high-definition real-time video. After a short experiment, I let my 11 year old child fly. He had no difficulty in manipulating the UAV around the buildings in the yard. The camera has only one angle adjustment, but you don't need more. It's really easy to take a good picture. A few days later, we started the beginner mode and flew the UAV to 260 feet. I believe it will fly higher. But it was almost invisible at that distance. I was nervous because there was a breeze. It kept its position and quickly responded to the control. We like the experience of rotating the camera to take photos. Then we brought it back to the place where we started. After a week of use, we learned an important lesson. Follow the calibration procedure. If you are flying outdoors, please do not fly without gps lock. The return function depends on the pre flight gps lock. Otherwise, if you get gps lock after takeoff, you will not know where your home is. This bit us twice. Once, when we got home, the drone crashed into the woods. However, no harm was caused. The second is when the low battery return to home function starts. We launched the UAV before the GPS lock, and the UAV flew toward the street. I could bring it down, but it didn't land as ordered. I strongly recommend not flying without gps lock, unless you force the UAV into optical mode. A warning pops up on the screen, which is really good for the designers who remind me of GPS. But it is not clear what effect the lifting of the warning will have. If there is no proper home, it will produce unpredictable behavior. This was my mistake, because I wanted to take off immediately, and I ignored the warning. So, learn from my mistakes and avoid collisions. We are very satisfied with the UAV and will recommend it. For a beginner's UAV, this is a bit expensive, but its functions are very powerful. The company has existed for a period of time, and parts are also easy to obtain. You may need to buy parts sooner or later, so knowing you can buy them is a big advantage. In addition, I would like to reiterate that you should make sure you have GPS lock before takeoff. Otherwise, if you encounter low battery or other conditions, you will not be surprised by where the drone flies. This happened to us. Fortunately, we were still able to land safely. The application warns you that you are not in gps mode, so this should not surprise you. After the third time, we finally learned a lesson. Another thing is that you really don't want to run out of battery power when you go home. If you are not in an open area. It's not a joke that the manual says it can't avoid obstacles. The UAV will fly to about 50-70 feet and return quickly. If it encounters anything on the way, it will not have a good ending. I suggest that the timer for each battery should be about 15-17 minutes. The battery is easy for us to maintain for 20 minutes, but if you limit yourself to 15 minutes, you won't get any surprises. We also made the first set of props and trimmed some leaves and branches along the way. The flight of this UAV are still very good.
