Many flying hands have blown up the machine. When encountering an accident, the most important thing is to keep calm and take prompt remedial measures. The UAV world has compiled 12 stories of accidental flying hands taking remedial measures in flight. Whether it is finally saved or not, I hope to give you some reference:
1 Once, during the process of shooting the lubricating oil company's oil storage tank, the aircraft compass was suddenly disturbed, flying at full speed in the opposite direction to the take-off point. All the joysticks did not respond, and the remote control could not be returned. Only the flight mode could be switched continuously. Finally, after the 600 meters out of control, the aircraft resumed control in the manual mode, pulling the aircraft back; the reason may be the interference of the digital radio station on the tank. At that time, the environment was more complicated, the signal tower high voltage line had, and it was not certain what the interference was.

2 At that time, the test flight in our reservoir was good. The surrounding environment was good. I watched some people walking. At that time, I was also in contact with the aerial photography for the first time. I saw people watching the aircraft performance and flight technology. The altitude of the aircraft was about 20 meters from the water surface. About 40 meters, in the GPS mode, the full joystick flies for a few rounds of 8 words. When the projector is ready to show up again, the aircraft suddenly turns up when the landing is over. The attitude is very unstable, and the attitude mode is switched quickly. It is invalid, and the manual mode is switched! Finally, the high phenomenon was stabilized at about 2 meters from the water surface, and then the attitude mode was switched. The aircraft pulled back and returned. As a result, the response of the aircraft to the rocker was almost zero. Only the right roll had a certain effect, and it was lucky. This direction is the shore, the right roll is full and ready to hit the tree directly, because the tree is a one meter high green belt, 20 meters high hit the tree crash, zero loss... The lessons learned afterwards are never Show off, don't do it! Especially when you have a beautiful girl, you can’t do it...

3 I was most impressed by the fact that my partner and I were invited to go to a resort in the suburbs of Beijing to shoot a video of the Great Wall. We used the Elf 3, when flying to 1500 meters, the height is close to 400 meters, this time is already super vision. From the flight, the aircraft could not be seen at all, and the image transmission was blunt. It was almost going to the Great Wall. I couldn’t bear to return. We chose to continue flying. When the screen transmission was intermittent, the plane flew to 2,100 meters. When the maximum ceiling was 500 meters, the precious picture was finally captured. However, at this time, the aircraft's power was less than 40%, and there was a phenomenon of out of control. There was no response to the rudder. We had to take the remote control while riding. The electric car in the scenic spot ran in the direction of the plane, hoping to shorten the distance from the plane, but was afraid that the battery would be exhausted and landed in an unknown area. After we chased about six or seven hundred meters, the ground station was restarted, and the picture was restored. Already alarmed, flying back is too dangerous. Finally, I chose the plane to shoot, looking for a relatively flat grassland near the wall, and then we

4 Once in the aerial photography operation, before the plane took off, the dji go app has already indicated that the compass is abnormal and needs to be calibrated. However, after the calibration, the magnetic compass will still be prompted from time to time. I think it may be caused by the proximity to the ground metal. After taking off, it will not be, so I thought I was able to pass the technology and still take off and work. After the takeoff, the compass was normal, and I flew with confidence. After the result of flying far away, the compass abnormality appeared again. The flight of the route could not fly normally. At this time, the plane had already flew out more than 500 meters, and it was barely able to see the posture. When I was focusing on the composition, the drone was not controlled. Colliding on the lamppost, my colleague around me reminded me that I was about to crash into the plane. I hurriedly climbed the oil and crushed the ailerons to avoid the bombing. From then on, I have remembered this lesson, and then the superb technology, not meeting the conditions for taking off, or not flying as well.

5 Thailand once flew indoors and positioned with ultrasound. At that time, some people might move underneath. The plane suddenly went down. I blocked it with my hand and pulled the plane up. The plane crashed into the roof and fell. I saw the airplane battery. Going out, plug in the battery and see if it can work. Ok, this time I found that all the blood on my hand and blood on the ground. In addition to the thumb, four fingers were hit, the other finger skins were injured, but the little fingers were stitched six stitches.

6 Once the Elf 2 aerial mission, the meteorological conditions are 5 to 6 gusts. There are buildings and enclosures around the take-off site. It just flew up and did not feel affected by the wind speed. There was no building blockage after about 50 meters and 150 meters. The aircraft suddenly drifted in GPS mode and the picture failed. Switching attitude mode pulls up the drone, the picture is restored, the height is about 75 meters, and the distance is about 170 meters. Because of the wind speed, the picture is invalid, the remote control is not responding, switching back to GPS mode, turning on the automatic return function, the drone is subject to the wind direction. The effect continues to fly in the opposite direction. Final bomber!

7 At the Hengshan Grinding Table, about 3 meters down, and suddenly a visitor walked over the landing point, and looked up, I shouted, yanked the joystick, I was forgotten myself. Which hand's finger first moved, then it flew to the side, hit the smoggy snow, then the plane was unbalanced, and then fell under the cliff guardrail.

8 I updated the firmware once, and after 2 minutes of takeoff, I lost control. I flew to the center of Qiandao Lake. I dialed the remote control rod and let the plane draw a circle in the air, slowly descending. The circle is getting smaller and smaller, and finally I drop it. On a tree, saved back.

(9) In July 2017, the political commissar and his team went to Barunhold, Inner Mongolia to conduct flight defense operations. The amount of flight defense operations was relatively large, and the food surrounding areas were trees. Before they went, they prepared for the work. In order to avoid the sudden accident of the plane, the political commissar carried out the flight on the route and avoided the obstacles. The early plane was a little problem, and the levitation was a bit large. The political commissar still thought about it. Hit it. When the plane took off and found the flight waypoint, the plane flew up and stuck directly. He forced the machine to stop when the plane was running. The plane fell and broke the pot. He said that although it was not for senior reasons, it was because the plane was floating. The big bomber, but the moment the plane fell, his mood was very heavy, and he kept a high degree of vigilance during the next flight.

(10) Wang Jun once demonstrated the drone flight for the customer. Because it was the first time to use this brand of drone, there was a mistake. At that time, he completed the equipment commissioning and was ready to take off. The wind was relatively large on the day. After the takeoff, the equipment drifted sharply. At this time, he was ready to correct it, but the plane moved forward. At this time, a customer took pictures in front, and the equipment was very close to the customer. Recently, fortunately, Wang Jun reacted quickly, the throttle increased, and the left aileron was hit, so he did not hit the customer. However, the flight altitude of the aircraft was very low, and the emergency operation was violent and unstable, which caused the aircraft to roll over and damage the arm. Later, it was discovered that the main reason for the accident was that the equipment inspection was not careful. Wang Jun simply thought that the red arm was the nose of the aircraft. Actually, the red arm of the aircraft was the tail, so it was wrong after taking off. Rudder.
(11) Another time was when Wang Jun took the class to practice training. When flying on the same day, the students had the difference between the American hand and the Japanese hand. The Japanese hand student had no problem at the end of the flight. When the first student of the American hand flew, Wang Jun put The plane took off to a certain height and informed the trainees to control the throttle stick amount to 50%. When Wang Jun switched to the trainer through the master control of the trainer, the aircraft lost power and went straight down. In less than 3 seconds, the plane was free. When the body fell to the ground only 30 centimeters, Wang Jun switched the mode to the coach mode for the first time, pushing the throttle to the full pole, and the plane finally flew upwards, and the plane was safely landed. The reason for the post-mortem inspection is that the trainer sets the channel and the amount of the throttle in the flight mode when the remote control is practiced. The setting amount is 17%. The most important thing is that the control channel given at that time is open, and the throttle stick of the trainee is as long as Above 17% throttle will turn off and the aircraft loses power.

(12) Xiao Dong also bombed the machine. It was a sunny day. In the afternoon, Xiao Dongxing went downstairs to shoot the sunset. The plane did not search for the stars and entered the attitude mode. Xiao Dong adjusted his height and confidently operated the plane to fly to the sky. When he wanted to fly over a 25-story residential building, the map was broken and the signal was broken. Xiao Dong encountered this situation for the first time and shut down the flight control in a panic. As a result, the Elf 4, which had less than 30 takeoffs, was gone. Xiao Dong’s experience of blood and tears tells everyone to remember not to panic when flying, and not to blindly control.
