Tencent's digital drones have now become the new darling of geeks, and have also revolutionized the professional and amateur film production/photography field. Although many drones are equipped with high-tech automation, it is still difficult or even dangerous to control it. And considering their high price, we naturally need to pay special attention when selecting and using. If you are interested in buying a drone or want to learn how to get the most out of your drone, this article contains everything you need to know.
The basic principle
1. Know your limits. If not properly controlled, accidents can occur on your unmanned body, such as falling from a high altitude, hitting an obstacle, falling into the water, or being disconnected. So the novice needs to keep in mind the following three points when controlling drones: Don't fly too high, too far and too fast unless you know what you are doing. Security features are also important considerations when selecting drones, such as automatic return and pause (stay in the air).
2. Consider the camera and the universal joint. In terms of image shooting, drones are mainly divided into two categories. One type of built-in vendor-specific shooting system, and the other allows users to install a camera, such as GoPro. Each of these two categories has its own characteristics. The former allows users to view the captured images in real time, while the latter not only provides greater flexibility, but also facilitates future upgrades at a lower cost. More importantly, there is currently no drone with a built-in camera that can exceed one GoPro in image quality.
High-end drones generally have powerful universal joints that are used to secure the camera at the bottom of the fuselage. Compared with a fixed-angle pan/tilt, the universal joint can significantly improve the stability of the picture, thereby avoiding strong winds or operating unskilled image quality. The universal joint is the key to the drone's ability to capture smooth video and still-life still photos.
3. Understand flight characteristics and functions. The drone is flying in a different way than a remotely piloted aircraft or helicopter. Its speed, direction and altitude are controlled by four fixed-angle rotors (6 or 8 rotor models are also available). The computer in the device is responsible for adjusting the rotational speed and angle of the rotor for flight control.
Most of today's new generation of drones support waypoint planning, follow-up and other programmable functions enabled by GPS. They can follow the planned route precisely, as if they were fixed on the track. With the help of security features, they can also return to the GPS marker's takeoff point with one click, stay stable on windy days, avoid the no-fly zone, or monitor the remaining battery to ensure that they can return smoothly instead of falling to the ground or river. in.
4. Pay attention to the safety of others. A drone is a dangerous device. Although they are small in size, the four electric motors are powerful, and the speed of the plastic rotors is very fast, which is easy to get hurt. Compared to the rare chance of falling from the sky and getting to the person, the controller should be careful not to let it hit other people or items because of misuse.
5. Practice your hands with cheap products. The average quality of drones starts at $400, and even better than $1,000, so you'd better master the basic flying skills before buying. Fortunately, there are a lot of cheap mini drones on the market that allow you to practice in the room or in the yard, such as Hubsan Q4 H111 ($22, about RMB 143) and Heli-Max 1SQ ($86, about RMB 558).
When you first learn how to control a drone, you must slow down and try carefully, and focus on basic direction training such as up and down, front and back, and left and right. It should be noted that when the orientation of the drone changes, the direction control will reverse accordingly, so it is best to keep it in the same direction as you to avoid mixing control. In addition, you need to keep the drone in sight and don't let it fly too high. If it disappears from your sight, even if it is only a few seconds, there is a risk of flying.
Finally, make sure that the drone is not around, especially children, while protecting your body parts, such as your fingers.
Recommended brand / model
Here are a few of the consumer drone manufacturers we have counted, and the models that are best suited to most consumers. There are no most professional (and most expensive) models in this list, so it is especially suitable for novices to use as a reference when purchasing.
