The editor said: I have not actually operated any drone with a weight of more than 4 kg, but I have seen dozens of people flying. I have summarized some guidelines on the safety of drones. I hope to buy drones. The novice has some help. 1. Never open the aircraft power before the official take-off. The aircraft will be turned off the first time after the flight. Do not touch the remote control when turning the power on or off. The take-off and landing process is when the drone is closest to the person. The speed of the propeller's propeller is very high, and the paddle is very thin, which is easy to cause damage due to operational errors. Therefore, it is the most important thing for novices to ensure that the drones do not move during the human contact. 2. Check before flight, take off, fly the drone to a vertical distance of about 4 meters away from the radius of 5 meters, check to determine whether the operation is normal. This is a simple one. If you drive a car, you can also look at the oil meter. Try the brakes. You must check the airplane. Remember the first sentence on the road when you passed the road test? "Reporting the examiner, the vehicle instrumentation is normal, whether it is activated," this is a reason. 3. Do not operate the drone in crowded places. I hope that every newbie will remember it! ! ! ! ! I will focus on it with Article 4. 4. There is a certain threshold for the operation of the drone, and the drone itself has certain dangers. Here to say a few more words, the operation of the drone is a skilled process, from rookie novice to cool play master is a long process, the operation is absolutely forbidden to play on. And the drone itself also has some uncertainty, the reason of the weather, the reason of the operation, the reason of the fuselage itself, the military drone, then the NB thing, not the same down? Therefore, every new entry player should remember this sentence: "To play the drone, you must prepare for the crash." So, go back to the third article, don't operate the drone in crowded places. I understand that everyone is just like me. There is a force in the plain appearance. I want to buy something good after I buy it. Take it for a while, but! ! ! ! Don't force it! Just said, there are many uncontrollable factors in the flight and operation process. In places where people are crowded, once the crash occurs, the consequences cannot be considered. Finally, I would like to say more, outdoor concerts, indoors are all no-flying places, because the indoor signal environment is more complicated, it is prone to interference and out of control, and the outdoor concerts are crowded and the consequences of losing control can not be considered. To say so much, I just hope that everyone has a fear of the drone. Every kind of toy is accompanied by danger. Although the drone is a low-altitude flying device, don't forget that he is in the sky, always guarantee safety awareness, and can have fun.
