2. How to play the novice drone?

Beginners, please make sure that one question is whether you just want to shoot something or learn more about drones. Then, please refer to the following suggestions:

1. If you just play aerial photography, it is recommended to start with a mature aerial drone, DJI's aerial drone. Then, after activation, DJI has supporting flight simulation software for novice training. First, fly a few times on the simulation software. After understanding the basic operation, change the flight mode to novice mode. After flying in novice mode for a period of time, you can fully master the flying skills. You can turn off novice mode in the application and then use GPS mode.

2. If you want to be an old driver who knows about drones. It is suggested to buy a set of simulator remote controller specially used for flying UAV model, and then practice with supporting simulation software such as Phoenix and G7. Then, look for information on the Internet and visit forums. Taobao bought a set of 450 four-axis accessories and assembled and debugged the 450 four-axis by itself. In this way, you will be familiar with various functional components of UAV, understand flight control, remote control, motor and battery adjustment, and then practice flying in GPS mode and attitude mode with 450 aircraft. When your attitude mode flies smoothly, you can try to assemble an aerial camera with a pan/tilt. Here you can learn the knowledge and application of camera, pan/tilt, picture transmission, display, video glasses and other accessories. When all these slip away, you can play DJI's drone, which feels like playing with toys. At this point, you can use any finished drone, whether it comes from DJI or not, and you can start learning how to compose pictures, transport mirrors and adjust shooting. How to grasp the shooting opportunity? At this point, what really plays a role is the tripod head and the lens. When you reach this level, the drone is just a familiar flying tool for you, and then you become an old driver of the drone.

However, as a novice, you must be conscious and safety first. You can't fly in sensitive areas and no-fly zones. No matter how good your skills are, don't do anything. Thank you.

3. How much do you know about drone safety?

1. Never turn on the power of the plane before the official takeoff, and turn off the power as soon as the plane lands. Do not touch the remote control when the power is turned on or off.

The take-off and landing process is the shortest distance between UAV and human. The propeller speed of UAV is very high, and the blades are very thin, so it is easy to cause personal injury due to operational errors. Therefore, the most important thing that novices should pay attention to is to ensure that the paddle will not move during human contact.

2. Check before flight, take off, fly the drone to a place with a vertical distance of about 4 meters and a human radius of 5 meters, and check whether the operation is normal.

This is very simple. When driving, you should look at the fuel gauge and try to brake. Be sure to check when playing with the plane. Remember the first sentence when you got on the bus during the road test? It is a truth to report whether the vehicle instrument is normal to the inspector.

3. Never operate the drone in crowded places.

I hope every novice will remember this one! ! ! ! ! This issue will be discussed in conjunction with article 4.

4. There is a certain threshold for UAV operation, and the UAV itself is also dangerous.

I'll say a few more words here. The operation of UAV is a skilled process. It is a long process from novice to Coldplay player. It is absolutely forbidden to play hard when you come up. There are some uncertainties in UAV itself, such as weather, operation, fuselage itself, and NB of military UAV. Isn't it different? Therefore, every novice player should remember this sentence: "To play with drones, you must be prepared to crash."

So, back to the third rule, don't operate drones in crowded places. I understand that everyone, like me, has a pretentious heart under a simple appearance. After buying something, they all want to install it as soon as possible, but! ! ! ! Don't pretend! As I said just now, there are many uncontrollable factors in flight and operation. In crowded places, once the plane crashes, the consequences are unimaginable.

Finally, I want to say one more thing. Outdoor concerts and indoors are no-fly places, because the indoor signal environment is complex and the interference is easy to get out of control. Once the outdoor concert is crowded, the consequences cannot be considered.

Having said that, I just hope that everyone has an awe of drones. Every toy is accompanied by danger. Although UAV is a kind of low-altitude flying equipment, don't forget that it is in the sky. In order to have fun, it is always necessary to ensure safety awareness.

4. What are the basic knowledge of multi-rotor UAV?

There are three types of drones: consumer, industrial and military. Consumers are mainly concentrated in four aspects, and more are entertainment. Industrial UAV has multiple rotors and fixed wings. Today, corbett UAV, let me popularize the basic knowledge of multi-rotor UAV.

1 definition of multi-rotor UAV A helicopter with three or more rotors is called a multi-rotor UAV or a multi-axis UAV. The rotor refers to the propeller that provides power, and the shaft refers to the rotating shaft of the rotor that provides power.

The naming of multi-rotor UAV is generally divided into multi-axis UAV and multi-rotor UAV according to the number of shafts and blades. For example, the picture above shows a six-axis six-rotor UAV.

According to the arrangement of the motor, it can be divided into single shaft single paddle and * * * shaft double paddle. According to the relationship between the direction of the nose and the installation position of the motor, it can be generally divided into I type and V type. The characteristics of three kinds of multi-rotor UAVs are as follows: Four-axis UAV is the most efficient scheme among all multi-axis UAVs. Now we choose multi-rotor UAV according to our different needs.

For example, what we need is a multi-rotor UAV with long battery life, and it is best to choose a multi-rotor UAV with a large four-axis layout. For another example, if you need a multi-rotor UAV with fast flight speed and good wind resistance, it is best to choose a * * * axis eight-paddle multi-rotor UAV.

5. What are the precautions for novices to operate drone aerial photography?

For beginners, we should first do simulation exercises on the computer, such as hovering, flying around and flying in figure 8. Remember not to directly control the real machine. After these skills are proficient, they use low-power training machines to fly in empty unmanned fields, then take aerial cameras to fly without load, and finally hang up the Yuntai for test flight. Finally, use a doggerel in the field of model airplane to remind readers: "There is no trivial matter in model airplane flight, and skilled control is the key. Beginners are good at asking questions and practicing, and don't show off when they are away from the crowd. Don't treat the equipment as a toy and ignore safety and regret it. " The following are precautions.

1, safety, absolute first, then NB control and camera, hit people and blow up planes, hahaha.

2.* * * "Black Flying", you can't fly in air traffic control areas such as military administrative zones and airports, stay away from crowds, and do your homework after obtaining shooting permission. You know, I once witnessed computer games being confiscated by police uncles and taken away for detention during the no-fly period.

3. Learn more theories. The more proficient the theory, the more advanced the flight technology and the more savvy it is in flight.

Luck is always the enemy of security. Lack of common sense and momentary negligence are the biggest threats to flight safety. Flying must be foolproof. If you are not sure about 100%, don't practice. The psychology of trying is adventure, and the probability of failure is the highest!

5. In order to ensure safety, it is necessary to check the safety of aircraft equipment frequently. Communicate more and dissect more accidents.

6. When flying, you should make yourself in the best condition and know your body, energy, emotions and feelings. As long as you are unwilling, lack of sleep, tired, depressed, feeling bad and under too much pressure, it may lead to operational mistakes and lead to great disasters.

7. When flying at low altitude, you must pay more attention to external observation, and you must pay attention to pedestrians. This is fatal! ! !

8. The first flight after a long grounding must be slow, steady, thin and complete.

9. Don't trust your feelings too much, don't think you are experienced, and don't be too confident.

10, fly more, practice more, and accumulate more experience. Over time, a hundred trials are tempered into steel.

1 1. In daily practice, we should take the initiative to understand the plane and learn to maintain and repair it so that problems can be solved on the spot.

13, the flight should not be neglected, and some emergency disposal methods are available at any time.

14, don't sit still and relax at any time during the flight to prevent relaxation and paralysis after landing, and the propeller is not turned off after landing.

15, to ensure safety at all times, we must ensure the safety of every flight.

16. reckless and contemptuous treatment of very serious flights is an important factor causing accidents.

17, flying happily is very important, but ensuring safety is more important. There will be tomorrow without today's cool flight, but there will be no bright tomorrow without safe flight.

18, don't fly after drinking, okay? ...

19, the battery must be unplugged in time after the electric plane flies.

20. If you feel that the plane is abnormal during the flight, please land and check it immediately. Don't be too confident. (Golden Eagle UAV)
