As a new drone flyer/Pilots, it will be better to know how to Choose Your First DJI Drone. For most experienced drones Pilots, parameters of drones show the Performance & limit of the drones, but if you are new flyer without the experience of DJI drones, how should you Choose Your First DJI Drone? According to the statistics of some after-sales departments of drone companies, about 70% of new flyers will blow up their drones within a month, most of the reasons are Operation Error when flying!!! If a new flyer blows up his/her drone as soon as he/she get the drone, What is the significance of the performance of the drone? So when new flyers going to purchase new DJI drone, it is no need to consider drones with complex and very advanced parameters. The safety, stability, and reliability of drones are the most important! *Safety of drones – obstacle avoidanceWhat is the most common reason for blowing drones up for new flyers? (1)The first is that they are not familiar with the operating rules of the drone. For example, Many new Pilots will drive their new drones unscrupulously in a narrow room, then drone out of control because there is no GPS signal, causing the drone to hit the wall. (2)Second, When flying outdoors, they do not notice the poor GPS signal when taking off, which Cause the drone to drift and hit the wall. (3)Third, many new flyers don’t pay attention to the head of the drone when flying, lose the sense of direction when operating the remote control lever, wrong shot, leading to a wall crash. (4)Fourth, new flyers fly the drone to the back of the building, lost the signal and then triggered the automatic return, but hit the wall because the return altitude was not enough. To new flyers, hitting the wall when flying is the No. 1 killer in the drone flying industry. Suggestion: When purchasing a drone, the new flyers should purchase one with obstacle avoidance capability. Although the drone with obstacle avoidance function generally has a higher price, it is better to come with a avoid obstacles than to come without avoiding obstacles. The price is high, but it is more cost-effective than the maintenance cost after the bomber.
In addition, drones with obstacle avoidance features generally have better visual positioning capabilities. The drone can also hover stably in a room with the poor GPS signal, greatly reducing the risk of the bomber. *Transmission of drones – stabilityWhen buying, Many professional Pilots will pay special attention to the Maximum distance of the transmission of drones. It is true that the distance of the transmission determines how far the drone can fly, But it does not represent the true performance of the drone transmission. The distance of the transmission traveled by the manufacturer is measured in an ideal environment without interference in the wild, but the actual environment is impossible without interference. To most of the new flyers, they are afraid of when the drone fly a few hundred meters away, flying a few kilometers away is neither safe nor necessary. Suggestion: Compared with the maximum distance of transmission of drones, the new flyers should pay more attention to the stability of the transmission.
How can I know if the drone’s transmission is reliable or not? Look at the following two points: 1/ Directional antennas can increase the transmission distance, but new flyers do not pay attention to the antenna pointing, it is easy to lose signal even at close range. The drones connected only by mobile phones have relatively poor transmission stability. Compared to a remote control designed specifically for drones, the of anti-interference ability the Mobile phone is weaker because of the Limited by built-in antenna design and transmit power limitations. So the new flyers should not buy cheap drones, it will be better to buy a drone with remote control.
2/ Coming with remote control, a drone using a directional antenna, its transmission stability is relatively poor. The directional antenna must face the drone then the signal will be stable. But most of the flyers have no idea about this, When flying the drone in a short distance, the antenna direction is not aligned with the drone, So there is a sudden loss of signal. In contrast, omnidirectional antennas are less likely to lose signals. Therefore, it is best for the new flyers to purchase a drone come with an omnidirectional antenna.
The remote control distance of the omnidirectional antenna is shorter than that of the directional antenna, but the pointing requirement is lower and stable at a close distance. *A battery of Drone — stabilityWhen buying drones, many people also pay close attention to their battery life. Some new flyer complain that: the phone can be used about the whole day, Why the drone’s battery life is less than half an hour? In fact, the experienced flyers know the reason: The average aerial shooting time is around 10-15 minutes. Half an hour of battery life is enough for many experienced flyers. Suggestion: Compared with the maximum battery lifetime, flyers should pay attention to the stability of the battery. One of the hardest problems for new flyers is not the endurance time, it also is enough for them to be able to fly for about 10 minutes. Some newbies, they insist on flying even when the battery is low, forget to count the time amount of return. Some newcomers only discovered it when they were under a low voltage warning, but it is too late to return. Now lots of drones are equipped with smart batteries, the smart battery can calculate the flight distance and judge that the remaining power is enough or not to return to the flight, promptly reminding the flyers, which will avoid the bomber. In addition, the maintenance of the drone battery is extremely important. Mobile phone batteries are used every day, and the batteries are often charged and discharged, which is easy to maintain; However, the frequency of use and the frequency of charging and discharging of drone batteries are much lower than those of mobile phones. Many new flyers do not know how to maintain drones batteries. The battery is easily accelerated due to long-term non-use, which will affect flight safety.
Fortunately, many drones batteries now come with smart charging and discharging design. *Three-axis gimbal of Drone — steadyWhen buying drones, flight performance is one aspect that should be thinking about, camera performance is another aspect. Some new flyers are not familiar with drones, but they have some understanding of the camera, knowing to pay attention to camera parameters at the first time: resolution, 4K, frame rate, bit rate and so on. But most of the new flyers don’t know that, the drone photography is very different from ground shooting: when drone photography, not only the shaking of the drone during flight will cause the camera picture to be unstable, the high-frequency jitter caused by the rotation of the drone’s propellers will also cause the jelly effect on the screen. Three-axis gimbal with three motors can offset the drone’s jitter. When buying drones, as a new flyer, rather than see if the parameters are powerful, it is better to think about whether this drone is suitable for you, and What is the actual flight experience of the drone. *Suggestion:For new flyers, when choosing the new drones, it will be better to think about the following four points:
(1)Come with automatic obstacle avoidance
(2)Transmission is stable and reliable and uses an omnidirectional antenna
(3)Use smart battery design
(4)Using a three-axis gimbal Here Recommended: DJI Spark / Mavic Air NOTED: The new flyers should read more several times and understand the manual, practice more, and be familiar with the flying app.
Pay attention to the practice site: should fly the drones in an open space without obstacles. -- AMZPOW
