Technology is developing too fast, and drones have become a tool for entertainment in life (activity: are you gossip?) tools. Flying gameplay and aerial photography have also become an experience for all major players. The author still has a special feeling for the plane. I still remember that when I was a child, I used a helicopter that could not fly to play around. When I went to middle school, I had the first remote-controlled aircraft that could fly. Today, I got the four-axis X402H drone from Megan, which is a step closer to the dream of flying into the sky. From the appearance, the Meijiaxin X402H is like a bird that takes off, and the eyes of the gods look very aggressive; its surface making process is still good and very handy; but I found that many of its vents are designed. At the top, if it rains, it can't fly. When I first got it, I saw that the flying paddle was so thin. I was really worried. In the process of flying, if I hit other objects, would it hang? Fortunately, I thought a lot. I was doing it indoors when I was flying, and I hit the wall no less than 5 times. It seems that its blade quality is still good; there are many times that the wall does not damage the motor. It seems that this is not fortunate, but its material is too hard, anti-drop, anti-collision must be the design standard of the drone. I thought about it for a long time at the beginning. Why is this extension cord used? Later I learned that it is a wireless transmission antenna that docks signals. Due to the short design of the whole machine, it is only placed on the frame. Some people say that drones are toys? The author thinks that this is really not a good boundary. The remote control aircraft can be said to be a kind of toy. If it is used for other purposes, it may be a labor tool. Just like the X402H, not only the remote control handle, but also the flight control of the mobile APP. But sometimes I am also worried that if the mobile APP controls the flight, it is easy to cause a loss of connection. This can't be done without flying. Therefore, when I am flying, I basically rely on the handle to complete the various operations, because I am also a novice. This is the first time I played a hundred-yuan drone. Because of the urgency experience, it was raining outside, so I played in the room for a while. I feel that the control of the Meijiaxin X402H is not bad, and the speed of rising and falling can be free. Control, and it is equipped with a high hover function, for many novices, don't worry too much that it will fly. As long as there is no clutter, you can easily perform operations such as micro control, direction adjustment, and rotating the body. After the weather improved, I went to the big playground to practice. To be honest, if you play the man-machine, you will get an empty place, otherwise it will be difficult to display your hands and feet. And for the 100-yuan drone of the Megan X402H, the new players have to practice more. Of course, novices can use it as an entry-level hands-on drone, and later they can play more advanced. The author did not do the related aerial photography experience this time. After all, this is a drone of about 300 yuan, plus its battery life is only ten minutes. If the camera function is turned on, it can be up to 5 minutes. This is not enough. . So I made three batteries to maintain it, but the most troublesome thing for me is that it needs to use a screwdriver every time you change the battery. It is really troublesome to open the position, and the power cord has to be re-connected. To say a word of peace, perhaps a hundred-yuan drone is like this, it will be good for you to fly into the blue sky, and the details need to be upgraded later, because its price is the most attractive place.
