Last year can be said to be the first year of consumer UAVs. On the one hand, all kinds of UAVs have entered the hands of ordinary people and become fashionable toys. On the other hand, the domestic market dominated by Dajiang has many price performance trend "leaders" similar to Xiaomi in the original mobile phone market.

The Star Dragonfly experienced on Leifeng. com is such a quadrotor UAV product. However, the tail confessed that although he had a desire to fly, he could only play with his son's helicopter model toy before, and he did not have professional flight equipment and aerial photography knowledge, but when communicating with the star map, I was touched by a sentence: dragonflies are born for ordinary people.

In combination with daily experience, I feel that ordinary users want to own and use consumer UAVs. Whether it's pure flying or to enjoy the beauty of aerial photography "God's View", it is nothing more than focusing on several key constraints such as portability, control, stability, image and endurance. The dragonfly drone Pro I am very satisfied with my performance in these aspects, and I also regret the limitation of equipment.

"Folding and modular design, portable bags, convenient and safe travel."

A big pain point of UAV is its large size, which is not convenient to carry. Especially, this kind of multi rotor UAV, whose rack, PTZ and boom are relatively fine, must be taken seriously to protect safety and facilitate use. Dragonfly UAV Pro The solutions of the system are modularization, boom folding and special bags.

Unpacked Dragonfly UAV Pro Except for a standard battery, all accessories are packed in a red special case. The bag is designed with handles, the two-way zipper is strong, and the bag panel is hard, which plays a certain role in impact protection.

Portable bags can one hundred and eighty The dragonfly's frame, landing gear, propeller, PTZ and camera, intelligent control watch, following module and some small accessories are all in place and have certain protective partitions.

Dragonfly UAV Pro Modular and foldable design is adopted. There are only flight control and four brushless motors on the rack. The arm is folded to both sides of the rack in front and back order. The size is 25*20*6CM , which is the size of a magazine. The machine material is PC The plastic and details are well made, and the seams are quite neat.

"Simple assembly, only two or three minutes after installation, and the installation of PTZ takes the longest"

After all, UAVs are not digital products such as mobile phones. There are some details to pay attention to during installation and control. Dragonfly's instructions have obvious hints. It is recommended that you read the instructions carefully before assembly. For example, the nose is in the direction of the PTZ, which involves the selection of rotor installation.

First, open the arm. There are four locking switches on the back of the dragonfly arm, which can be extended to the right position from the back to the front. In order to control the weight of the rack, Dragonfly uses carbon fiber materials in the boom, and the weight of the rack is six hundred gram . The front of the top of the arm is the motor, and the back is built-in LED The indicator light of can display the body status.

four When the robot arm is fully opened, it looks like the following. You don't understand why dragonflies look like a roasted sheep and a world of food.

Dragonfly UAV Pro The landing gear of is connected to both sides of the rack through buckles, and the bottom is provided with anti-skid rubber strips. So is the landing gear PC Plastic material, hollowed out and grooved to minimize the weight, but I feel the landing gear is a little thin, after all, after installing the PTZ, camera and battery one point two Kg Heavy, always worried about being unable to withstand the impact of landing. However, there is no problem now, and the manufacturer should test and verify it many times.

Dragonfly UAV Pro Using two thousand two hundred and twelve Brushless Langyu motor, standard nine Inch propeller, it seems that power matching is also a profound knowledge, so we don't care about beginners. Dragonflies are self-locking oars. There are locking arrows on the blades. Two are a pair. They are installed diagonally. They are distinguished by silver and black oar caps. Pay attention to the front and back, or they will not fly.

Dragonfly's PTZ and camera have been installed together at the factory, and there are better cameras that can be replaced by themselves. The PTZ is connected by the buckle and screw on the rack. The stability is no problem, but the screw is right in the middle of the PTZ rubber pad. The installation is not very smooth. It needs to be tightened slightly, which is also the most time-consuming part of the whole machine installation.

The last step is to install the battery. Just press the snap and push it into the battery compartment on the rack. Here, dragonfly drone Pro The installation of is completed, and the wheelbase is 40cm , which happens to be in the Dajiang Spirit two And elves three It is also a relatively large wheelbase among small UAVs.

"Smart watches, diversified automatic modes, and following modules greatly reduce the threshold of control. The remote control is not equipped as a standard, which is a pity for advanced users."

Dragonfly UAV Pro The main push is to select diversified automatic modes and simple control with one key through smart watches and smart modules. In this way, ordinary people do not need to learn to operate complex remote controls, but simply assemble and use them. They can focus more on their own affairs and let Dragonfly UAV Pro Follow the beat freely.

Dragonfly UAV Pro The smart watch is just like a daily sports watch. The strap is very soft and comfortable to wear. There are a total of ten Keys and one Five paddles, achieved by short and long press twenty Different functions. For example, the first key on the left, a short press means takeoff, and a long press means the fuselage rotates to the left; The first key on the right, short press to follow, long press to rotate the fuselage to the right.

The screen in the middle of the intelligent dial can display the dragonfly drone Pro Of GPS A series of information, such as signal, height, power, movement status and the status of the following module. However, the screen material is a little LOW.

Let's start with a simple takeoff and landing operation and performance. Open the Dragonfly UAV in turn Pro And smart watch power supply. After the aircraft self inspection and star search are completed, long press the smart watch unlock key, the propeller starts to rotate, and then press the takeoff key to take off. Dragonfly, for safety, unlock six If the takeoff key is not pressed in seconds, the propeller will stop rotating. During this period, dragonflies took off and landed several times, and their state performance was relatively stable.

Dragonfly UAV Pro The takeoff speed is one rice / Seconds, will automatically rise to five rice Hover. The following is the GIF image display of takeoff status.

Dragonfly UAV Pro The landing speed is zero point five rice / Second, if the speed is slow, it can effectively protect against impact and also remind the ground crowd to find out. At the same time, dragonflies sometimes bounce several times when they touch the ground when landing. It should be to check whether the landing position is appropriate. The following is the GIF image display of landing status.

Dragonfly UAV Pro And the smart watch has several useful control presets, such as spin and fly around. Spinning is where dragonflies go three hundred and sixty Degree rotation, flying around means circling around with the user as the base point five rice Radius flight. These can be controlled by a smart watch with one button. Spin and surround are suitable for some beautiful places. Use "God's perspective" to shoot beautiful scenery, especially surround can make the camera aim at you three hundred and sixty Surround yourself. The following figure shows the Dragonfly UAV Pro Spin GIF image display.

Dragonfly UAV Pro The following module of is designed with wrist strap, and there are charging ports and switches on the side. Through the cooperation of UAV, smart watch and following module, the UAV can automatically follow the camera. According to the test, the UAV's response to the user's action is still relatively accurate, and it can make corresponding actions in time. However, it is recommended to use the following function in the open area. Here are GIF pictures and videos showing the following status. Thank you for your friendship.

Dragonfly UAV Pro Built in GPS , gyroscope, barometer, magnetometer, accelerometer and other sensors can return with one click through smart watch. The official return accuracy data is the takeoff point one rice Within the scope, the actual test results are also one rice Inside. The following figure shows that after takeoff twenty rice After many flights, the landing point and takeoff point after one click return are compared.

From Dragonfly UAV Pro From the perspective of control, the idea of using smart watches to free hands is really good for ordinary beginners or outdoor enthusiasts. However, the simplicity of smart watch control also brings the problem of insufficient accuracy, real-time and freedom, and the flying height and flying distance of smart watch are twenty rice and thirty rice , remote control is one hundred and twenty rice and five hundred rice In this way, advanced users are in a bit of a hurry when watching the aerial photography effect of the mobile phone while using their watches to control complex actions in some complex scenes. At this time, if the remote control with the mobile phone bracket is equipped as standard, it will save much effort. Smart watches also have slots. It takes some time to get familiar with the complicated key design, and the control signal sometimes has a long delay. The position of the pan tilt control wheel on the smart watch is uncomfortable and not very sensitive, and there is an obvious control gap on the left side. Hardware needs to be optimized.

"The flight control system automatically resists the wind and controls the balance and the performance of the PTZ is good. The video quality of its own motion camera is satisfactory."

The maximum speed of the Dragonfly UAV is twenty-two rice / Seconds, encountered in multiple tests four The wind force is about 20 degrees, and the gust may be even stronger. At this time, the dragonfly drone can be clearly felt through the state of the dragonfly fuselage and the sound of the propeller Pro Control balance. When encountering greater gusts, the dragonfly will automatically lower its height if it is in a higher position. The tail has never played with a more high-end UAV, so it is impossible to make a comparison, but for dragonfly performance, I have enough confidence in flying aerial photography in a gusty environment.

Dragonfly UAV Pro Using three The elastic rubber pad at the connection of the axis self stabilizing PTZ is very good. Whether the dragonfly is hovering or flying, it can ensure the stability of the camera to a certain extent.

GIF pictures are used to show the extremely unstable state of the aircraft in the sky with dragonfly in hand, no matter how the fuselage shakes from front to back, from left to right, three Axis PTZ keeps the camera in front.

The following GIF pictures show dragonflies in the air and remote control the PTZ with smart watches ninety Degree pitch.

The original PTZ is equipped with 4K Distortion free motion camera, Sony IMX206 CMOS Photosensitive chip, photo quality 1600W Pixel, maximum support 4K Video recording is in order from the perspective of effect. If there are higher requirements for video quality, it can be replaced GoRro Size of the motion camera.

Dragonfly UAV Pro The motion camera on the WIFI Dragonfly camera on signal and mobile phone APP Connect to realize wireless image transmission, and set and switch photographing and video on the mobile phone. It is suggested to add post production function to realize shooting, post production and sharing in APP Synchronization completed.

Tail wanted to use dragonfly to take some aerial videos to show his hometown and life from different angles. Unfortunately, in complex scenes, it is too difficult to complete the control with a watch. Therefore, we have to simply carry out several video presentations to profile the dragonfly drone Pro It is different from the stability of PTZ, the video quality of the camera, and "my world is different". Leave a thought here, looking forward to dragonfly drones Pro After the modification of the remote control, you can experience it at the first time and complete the unfinished aerial photography idea.

Dragonfly rises up beside the former residence of Pu Songling, the "king of short stories in the world". Unfortunately, there are towering ancient trees inside, and the watch control dare not go deep. Look outside at the tea shed, the tree, and the well where Mr. Pu wrote about his strange stories in Liaozhai. Did you find the fox fairy?

The tail hometown was called Prajna in ancient times, because it is located in the sun like water. Dragonflies take aerial photos along the river to show the scene of "shallow rivers reflecting clear sands" described by Mr. Pu Songling.

On a foggy day, during the test flight in Liuquan Wetland, I ran into two old people and their granddaughter for a walk, and recorded this moment of kinship from a different perspective.

"The 30 minute endurance is good at present."

Dragonfly UAV Pro The battery capacity of is five thousand and five hundred Milliampere, the official endurance is 25-30 minute. Because the tail is in the north, it is still very cold this winter. I was worried that the battery efficiency would be affected in the cold environment, but in the actual test, it basically remained at twenty-five If you fly until the aircraft gives an electrical alarm, thirty There is no problem with minutes. This achievement is quite good for this kind of rotor UAV.

Dragonfly battery is charged with a special balance charger, and the charging time is 2-3 It takes about three hours to complete, and the heat generated during charging is also small. At the same time, other smart watches, follow modules, cameras, etc USB Cable charging is enough.

To sum up, Dragonfly UAV Pro The performance in all aspects was good, there were also many highlights, and several slots were also discussed in the sharing. At present, Dragonfly UAV Pro It is very suitable for people who like outdoor sports and need simple aerial photography. Tail also expects that this summer's seaside holiday will enable dragonfly to record the joy of the family, and also expects to experience the remote control later to complete those unfinished aerial photography ideas.

Today, I flew, did you fly?
