Compared with manned aircraft, UAVs are often more suitable for tasks that are too “dirty or dangerous”. UAVs can be divided into military and civilian ones according to their application fields. In military terms, UAVs are divided into reconnaissance aircraft and target aircraft However, with the gradual upgrading of consumption, drones have become a hot toy for people! Aerial photography can be easily realized by using this UAV, which is absolutely a sharp weapon! So how can we choose the right UAV? Brand, price and function are factors that can’t be ignored. Let’s take a detailed look below!
Precautions for UAV purchase
Battery life
Just like smart phones, UAVs will eventually run out of power. Even the best models can hardly fly longer than 30 minutes Of course, you can carry extra batteries at any time. Please be sure to include the cost of backup batteries in the total price of the options you are considering
Brushless motor
You may encounter this term Brushless motors cost more than bristle machines, but they provide quieter operation and have a longer service life, which means you don’t have to replace them often
camera
If you want the best quality lens, camera specifications should be a consideration. So be sure to look for the photo and video resolution of the UAV camera Most models (excluding toy drones) now have built-in cameras, but some will let you choose to install your own cameras
Headless mode
Starting flying drones can be tricky, so for beginners, some models offer headless mode Headless mode is to remember the orientation of the nose at takeoff. After the secondary function is turned on, no matter where the nose turns, the one that is consistent with the orientation of the nose at takeoff is the nose That is to say, the aircraft head you see is no longer the one identified by the remote controller, and the takeoff direction is the “head”. Integrated GPS: at the high end of the UAV market, you will find models with integrated GPS, so that the machine can know their position in the world. Many UAVs can hover in one place easily through GPS
Follow mode
Some UAVs equipped with GPS also provide this option: follow mode allows your UAV to track on the ground or sea, so you can focus on cycling or walking, while friends in the sky will record all this
a universal coupling
When the price of UAVs rises, you will notice that they start to have something called an integrated universal joint. It can keep the camera stable when moving at high winds and high altitudes (smaller toy drones won’t have this accessory, but they don’t really need it because they often fly indoors or at a lower altitude.) if you want the best videos and photos, make sure the drone includes a universal joint
Avoid obstacles
The advantage of some advanced UAVs is that avoiding obstacles will cost you money, but it may just protect your UAVs from hitting trees.
Range
The range of the UAV tells you how far it can move before you lose control. The more expensive professional UAV has a larger range No matter how far your drone can fly, please remember that you must see it at any time, otherwise it may never fly back
Four steps for UAV purchase
1. Select the one that meets the demand
The improvement of aircraft performance will inevitably lead to a sharp increase in price. More advanced aircraft often means more complex maintenance. It is unnecessary to pay for unnecessary performance. It is enough to buy performance just to meet the demand, and a little redundancy is enough
2. Helicopter with stabilizer bar
There is a short cross bar on the main rotor of the helicopter, which is the stabilizer bar of the helicopter The principle is similar to that of a gyroscope, which can improve the stability of a helicopter, make it less likely to get out of control, and improve its wind resistance. The structure of this thing is very simple, but it involves dynamic balance, so it requires high processing accuracy. Otherwise, those larger oil powered helicopters will backfire after they are installed. Because of this, this pole can become a benchmark for the technological level of helicopters
3. Select Professionals Sales
When investigating the alternative UAV Systems, the first thing to deal with is sales. Only professional sales know how to meet the needs of customers. Conversely, professional companies can naturally cultivate reliable sales. If sales are not professional and only rely on marketing to discredit opponents, the overall level of the company can be imagined
4. Choose expensive ones
After selecting the required UAV type, how to decide after shopping around? I suggest buying expensive ones. ” “Money for goods”; It is the most basic economic principle. There is always a reason why you are expensive. Especially for complex machinery such as aircraft, the details of your model are better, and the reliability is better. For most non expert users, it is not wrong to buy expensive. Even if there is a bidding by the whole expert team, the competitive products that are lower than the average price will be deducted points in the bidding scoring. Things that are too cheap will definitely have problems
