preface

In the domestic UAV market, more and more manufacturers join in the hope of sharing a share. Dajiang, ZeroK, Yihang, Zhidao and Feimi are constantly brewing more advanced products. As one of the competitors in the UAV industry, Starmap must have its own set of trumpets if it wants to occupy a place. If you are a player in the field of UAV, you must have seen many classic and even magical masterpieces. The world is full of wonders. Many beautiful sceneries are beautiful after aerial photography from the perspective of the UAV God; But I think you have also seen all kinds of videos of aircraft bombing, such as operational errors, tension after no image transmission, close contact with buildings and trees, positioning failure of visual sound waves on the water, hanging firecrackers and crashing, and all kinds of UAV bombing events also make people laugh and cry. Safe, relaxed and natural control is the realm that many junior players want to reach. However, without a long time of practice, it is impossible to achieve the control of flowing clouds.

Starmap starts from the above problems and is committed to making it easier for players who like UAVs to control it. The first generation of Dragonfly UAVs is equipped with a watch type remote control as standard (remote control and image transmission can be purchased separately). The biggest feature of the watch type remote control is that it does not need too many operations, such as fixed-point surround and automatic follow, which can be achieved by one button operation. In the Dajiang series UAVs, we need to carry out more complex steps such as gear shifting and setting options. In the evaluation of the author in this issue, we found that the biggest disadvantage of the watch type remote control is that the remote control distance is short, but its one button operation makes flying easier, which is more conducive to the natural control of the UAV by junior players, so that we are not too nervous when playing with the machine, and can fly easily with one button!

Next, the author will take you from the appearance of the Dragonfly UAV | assemble | Take off and landing, function advancement (surround, follow), endurance, ease of use and other aspects of experience and evaluation. Students who like UAVs, please click the video for more content.

appearance | assemble | Take off and Landing

The Dragonfly UAV sent by Lei Feng.com this time is the first generation black version. Compared with other versions such as red and pink, the black version is relatively calm. This is why Dajiang Wu came out with a black color Pro The reason of the version, from the sense, black seems more professional.

All parts of the product are placed in a red portable bag, which is more convenient for us to carry. include GPS Module, battery, host, two axis PTZ 4K All parts, including camera, watch, landing gear and propeller, can be stuffed into this small red bag.

The assembly of the Dragonfly UAV is very convenient. With the personal experience of the author and friends, it basically costs 3-5 Minutes. At the end of this section, there is an explanation of the assembly video I recorded. Please remember to watch it.

The size of the Star Map Dragonfly UAV and the Dajiang Spirit three The series is the same, and the propellers of the two are common to each other. Both of them adopt the propeller design with black and gray marks, which is more convenient for us to identify the diagonal installation position and tightness direction of the four propellers.

The star map is equipped with customized products 4K HD camera, maximum support 4K 15FPS Resolution recording, of course, we usually use 1440P 30FPS perhaps 1080P 60FPS It is enough to deal with general scenarios. The parameters usually look beautiful. Through later recording, the author thinks that the first version of the Dragonfly camera is not perfect. Now the official website has produced Pro The version of Dragonfly UAV is said to be 4K The camera has been greatly improved and needs further experience.

Two points must be ensured during the first flight: one ensure GPS achieve fifteen More than; two Make sure you are in an open area. The reason will not be repeated because GPS There are too many instances where insufficient space leads to unstable hovering and the impact of buildings and branches leads to the explosion of aircraft. Turn on the dragonfly watch, press the power button and the UAV automatic matching connection to turn off the red light and blue light flashing, adjust the position of the camera, and then fly. Dragonfly's cloud head is not a three-axis cloud head, but an ordinary one that can only go up and down ninety Two axis PTZ with degree rotation Pro In the version, dragonfly has been upgraded to three axes.

We will not focus on the specific buttons of watch remote control in this evaluation, because Pro The version of Dragonfly UAV is about to be sold on the official website. It is reported that the remote control function keys of the new version are slightly different, so you don't need to remember the position of each function key in advance. It's not difficult to get started. In short, it is divided into short press and long press to achieve different directions, functions and other operations. What's more puzzling is that the effective distance of watch remote control is only twenty Migao thirty Meters away.

Dragonfly is more careful about safety. When the unlock key is pressed, the dragonfly starts to turn on the propeller on the ground instead of rising directly, so that it can find problems immediately. stay six When there is no other operation within seconds, the dragonfly will automatically stop the motor, six Press the takeoff key within seconds, and the aircraft will take off.

Dragonfly UAV App The client is actually the client of PTZ camera at present WiFi To connect to the camera's wireless signal, so its effective distance is fifty About meters, far more than the watch remote control distance. In the client, we can set the camera's frame rate, save duration, delay photography, continuous shooting and other functions.

The author is a drone player of Dajiang Spirit, facing the spirit three The dragonfly has no fear. You fly and I fly. Consistent with the Smart series, in the flight state, we can view the current endurance state in real time through the power display behind the body battery. Of course, we can also read the power value directly from the watch remote control.

After pressing the takeoff key, the dragonfly unmanned opportunity will rise to five M high and keep hovering, as long as GPS The number is enough, and hovering is completely free. However, the author would like to emphasize that the Dragonfly UAV is not suitable for playing in windy weather. Compared with the higher priced Dajiang, its hovering in windy weather is slightly worse. When the wind exceeds four After the tenth grade, dragonflies will not only shift from front to back, from left to right, but even up and down, which makes people feel very confused. Therefore, it is recommended that you fly in sunny and windless weather.

Next, the author presents an article about the assembly process of the Dragonfly UAV, as well as simple lifting and hovering operations. There is a voice explanation. Please give more advice on the shortcomings.

Advanced Functions

In addition to the normal takeoff, hovering and landing, the Starmap Dragonfly UAV is good at spinning GPS Fixed point orbit and auto follow. First, let's watch a function test video about dragonfly spin. Note that in this video, except for the spin part, the remaining two segments are fairies 3 4K The video recording of version V and Dajiangwu is for you to compare the recording clarity of the three for reference.

The second function is the dragonfly's fixed-point surround. When we press the corresponding surround button, the dragonfly will automatically GPS The module is the reference point, for example, we can GPS The module is tied to the arm, so that the dragonfly will start to draw a circle around us. At the same time, the dragonfly's lens will always face the center of the circle, which is commonly known as the pan brushing mode.

The third advanced function is automatic follow. When it is opened and followed by one key, the dragonfly will also GPS The module is the reference point, and the lens faces GPS Module and follow. Whether we go straight ahead, backward or zigzag, the dragonfly will automatically follow and reverse the direction of the nose. Let's watch a video about the experience of surround and follow.

More ways to play

A person playing drone is always self entertainment. A good friend playing drone together is really happy! Well, the author has invited several friends to experience different types of UAVs. This time, the author will control the dragonfly, and two friends will control the Dajiang spirit respectively three With Dajiangwu, let's have a UAV sprint.

Today, the weather is not beautiful. Although the weather is particularly sunny, the wind is fierce. The northeast wind is blowing, and it is still beautiful and "freezing". Good thing three The drones don't complain. Well, they never seem to complain. Ha, just a joke. It's late and fast, three The drones are ready, hovering on the starting line, ready to go!

The name dragonfly sounds good, meaning small, flexible and hovering. From the speed point of view, the Dragonfly UAV does not have an advantage, because its control can only move back and forth, left and right by pressing the watch button, which is somewhat awkward. It can be handled with one key without surrounding and following. Fortunately, the two Dajiang are more gentlemanly, three All drones reached the destination at the same time. On the way to the competition, there was also a small episode, the second whirring spirit three What's the matter with all the problems? Let's take a look at the following UAV sprint competition MV Well, there is also voice commentary.

Endurance

Battery of Dragonfly UAV 5500mAh It is very powerful. Through the experience test, the endurance of dragonfly can reach 25~30 About minutes, compared with Dajiang twenty The endurance of minutes is much more powerful. On the contrary, the endurance of the camera can not keep up with the rhythm. It is often because our dragonflies have electricity, and the camera has already automatically shut down. Please note that the dragonfly battery must be aligned according to the symbol on the plug when charging. If it is inserted reversely, it will be useless even if it is charged overnight.

In terms of charging time, the time from low battery to full charge is three About an hour. Without a backup battery, it is a painful thing. Because after every flight, it means driving home to recharge three I can't go out again until an hour later. What about this? Are you just waiting?

Dangdangdangdangdang! It's time to make a coup. What you see now is two big clamps, which are clamped on the big battery of the workshop forklift. Is this violent charging? Ha ha, don't be nervous. Let's take a look at the specific situation.

This artifact is a necessary tool for UAV players, especially DIY A must for drone players. Home travel, kids and seniors are fools. In order to avoid advertising suspicion, I won't say much about the specific model and details. You only need to know that using it to charge can not only boost the current, but also see the current voltage of each battery pack. From the display, we can know that the batteries of the Dragonfly UAV are three Battery packs. Some friends may question whether such charging will damage the battery? The author specially consulted friends who played aerial photography and technical representatives of the Star Map UAV manufacturer, and secretly said that the manufacturer's technicians said that they did the same thing ~ But then again, half an hour is enough to charge it. It's really powerful!

Difficulty in getting started

The whole machine is not available 1.2kg The weight of the dragonfly must be more than wrong for a girl to carry, so first of all, there is no pressure on the dragonfly to carry. Don't underestimate the girl in the picture, she is a famous local aerial camera player... Your wife, uh huh.

Even the zero based enthusiasts have no problem playing with it. For girls with a lot of flight experience, it is simply effortless. In addition, the remote control of the dragonfly watch is easy to use. One button can surround and follow. I have to say that the star map is designed carefully in terms of control, making users feel more comfortable.

summary

Finally, a report will show you some main parameters that you care about. In this experience evaluation, the author has the following feelings:

one Dragonfly UAV is made of carbon fiber, and its fuselage is more solid than other brands such as Dajiang.

two Watch remote control has both advantages and disadvantages. One button operation is very easy for users to use; But at the same time, if an accident or dangerous situation occurs in flight, the watch remote control is obviously not conducive to aircraft rescue.

three The pan tilt camera does not use three-axis anti shake, and the actual recording definition is not satisfactory. The battery life is not as good as that of the dragonfly host, so the dragonfly is still flying in the sky, but it is unable to record more scenes (the new dragonfly Pro According to the manufacturer's personnel, this model has been upgraded. Three axis anti shake plus battery upgrade, please pay attention.

four In windy weather, hovering is prone to large deviation, so it is not recommended to fly in windy weather.

five The distance of watch remote control is too short to meet the higher view of God, although handheld remote control can reach the highest one hundred and twenty M, farthest five hundred Meters, but the standard version of Dragonfly UAV does not have a hand-held remote control + Image transmission, so it seems that the cost performance ratio is not very high.

That's all for this evaluation. In fact, during the author's evaluation, we can already see the dragonfly on the official website of Starmap UAV Pro The pictures of the new version are available, but there are no specific details. It can be seen that Starmap is also constantly improving its products. In the drone industry, most brands are still in their infancy, so they still have a lot to do and face many problems. But as long as you have a dream and believe, a new sky will be created eventually.

Finally, I would like to thank Lei Feng for its product testing, and wish Lei Feng would integrate more play methods into its future products, so that everyone can jointly maintain the authenticity of the evaluation and make more interesting and meaningful product evaluation. At the same time, thanks for the strong support of local UAV friends. With you, my work is more wonderful! Thank you!
