Understanding the drones should be started from Dajiang. The Phantom series that came out at that time was really handsome. Before it appeared in the aircraft, in my understanding, because there was no camera function, they were all unified into the category of the model aircraft (forgive me Only evasive. So always thinking about wanting to get into one, take a picture of a bird's-eye view from above, or a magnificent perspective of God, whoever mistakes himself for being the protagonist of the world. And then slowly concerned about this aerial drone, until this time the grandfather home surveyed Warren MR DRONE, completely subverted my previous knowledge of drones.
So so far I have zero flying experience on drones. Although I am a car god, it is a set of tests in terms of test drive, but in the field of drones, I am a newcomer and may be the one that has not even been tested. How to plan this white paper, I have to think about it. Therefore, the following assessment is based on the opinions and opinions of a pure amateur person. He also invited Haihan to make mistakes.
Established in 1994, Guangzhou Hua Kerr Technology Co., Ltd. (abbreviated as WALKERA) is headquartered in Guangzhou and is an unmanned aerial vehicle manufacturer integrating R&D, production, sales and service. Welch focuses on the development and sales of personalized, miniaturized, consumer drones, and also provides complete solutions for agriculture, firefighting, soil resource measurement, and energy industries.
The company owns two sub-brands, walkera and devention. Now it has established wholly-owned subsidiaries in North America and Europe. Its products are exported to more than 100 countries and regions in the world, providing global users with high-quality personalized drone consumer products. We are fully aware that the company's progress every day is inseparable from everyone's concern and support. We will continue to innovate, improve our business, and provide you with better products and services. ( http://cn.walkera.com )
As one of the world's top ten drone brands, Warcor, the design and quality of the product can stand the test of the market, and this time in Beijing Jingdong on the public to achieve mixed drone MR (Mix reality) DRONE, is said to be Since 2014, it has started research and development projects until the product is mature. In addition, Warburg, which has a solid strength, overcame people’s views on the fixed mode of consumer-class drones, directly crossed AR and VR, introduced more features and scenes of MR, and created drone+entertainment models. How Warlock's attempt will bring a kind of market prospect to MR DRONE and the whole drone. It will take time.
The protagonist: MR DRONE, based on the Runner 250
This time, there is no Zhang A-Mao's original packaging, but the Jingdong public raised directly from the company. On the first day after the end of the 23th Jingdong crowdfunding project, I received a call from the marketing department of the company Hua Ker Company, saying that MR DRONE was difficult to control and replaced an Aibo drone with the same MR function, but I still chose this one. . I do not know what the purpose of this telephone staff is? It makes me feel awkward.
It is easy to see that the MR DRONE packaging still uses the Runner 250 box.
Because there is no new packaging, the information on the box is Runner250, but the production capacity can not keep up, I can only comfort myself, because I finished this report, Waller's official website has not been on-line MR DRONE products.
Brand new, the film did not tear, one on each side. Even if other boxes are used, quality control should be controlled.
The foam box is fixed so as to avoid collision and damage of the accessories during transportation and transportation.
The upper cover has a layer of meticulous place, which is much more conscience than the front hood of the bird car in my house. Looking at g to build an aircraft and building a car is not at all on a level.
Out of the box family portrait, I can't wait to get him to take me with X and fly with me.
There are altogether two oars, so as not to break the oar as I am a newcomer, the battery is also two, although MR DRONE's life is not long, only about 12 minutes, two are not half an hour, but for the first to fly I'm enough. It's even more stressful than when I first drove.
How deeply feel that this remote control somewhat despise my feelings.
End the box. . . . . . . And so on, it seems that the accessories are not complete, the public test is written on the price of 3999, let me go to Jingdong to see this level of accessories
What about the bag? Big brother my bag? Well, the phone Wakol, got a very positive, certain and certain answer: Sorry, all users have no package. No bag, no bag. Yes, there are no packages in the back of my mind. After I left for a bombing, it was a chicken in my left hand and a duck in my right hand.
Have an aperitif before dinner
The parameters were well-written, but at first glance I thought I was back in my student days. I could read the words and I had to go one by one to check the relevant information.
1, the overall host aircraft
A very beautiful passing machine, how many people bow down to her gown, anyway, I am.
The aircraft has a high degree of integration, adopts a new industrial and modular design, improves the product's scalability, facilitates installation and maintenance, and replaces and upgrades. Take out the paddle and the battery can fly. In addition to the four feet, the all-in-one body carbon fiber composite structure is characterized by superior toughness and strong impact resistance. After all, for a passing machine, bombing is a common thing, unless you have been using GPS mode, then why not buy a Taiwan aerial camera?
Perhaps many people will say that it is interesting to get through the machine and assemble it yourself. Having said that, it can also be configured according to individualization, but there are no shortage of novices in this world, or people with less hands-on capabilities. This is a very good choice. After all, assembling a passing machine requires debugging various parameters and adjusting various components. There is a balance between the two. If there is a difference between the two, the flight will not be stable and the points will be shown to you. Really, it is very heavy. The person who likes to challenge himself is another person, and it is quite arrogant to fly a plane that is assembled with parts one by one.
Therefore, choosing a finished product is not a good choice. In the face of fame and fortune, this machine is very pleasing when it is not on the table at home or in a bookcase. But what? Slots also have
Why the battery line is so exposed to the red fruit, two long and short tails, seriously affecting the appearance. If it can be made into a one-piece aerial camera, the overall sleek at the tail, from afar, thought it was an AWACS. If you don't understand the first time, please ask the old bird. (Brain replenishment may be due to a high rate of blows. If you do not drop the buckle, you will waste it.)
From the figure, four red LED turn signals and two red tail lights can be clearly seen. The turn signals are only responsible for the work when turning. The responsibility of the two tail lights is a little heavy, basically covering all the instructions in the working state. Therefore, before you fly, you must familiarize yourself with the instructions, familiarize yourself with the specifications and instructions.
The new machine is beautiful, like a new car, bright and bright, suddenly there is a feeling of not flying, so before you fly, you have to take a few more shots, otherwise you will fly back and make a mouthful of grass, as shown above, this is my rub. Passed. Send a Doraemon Theatrical theme song <<Treasure>>.
The no-load quality is 456G, which is very easy to remember. Lightweight is the primary task of passing the machine. It can guarantee flexibility and can be faster, higher, and stronger. . . . .
Battery 183G, if I'm not mistaken, then it should be 639G. For the 250-axis machine, it should be considered even-sophisticated. It may be slightly biased. (I know you're going to say something heavy. I've been downgraded. After all, he used some weight I didn't know about the finished machine.)
There are 5V power sockets and SBUS/PPM interfaces on both sides of the fuselage. I don't know what to use. Baidu said for a moment that it supports SBUS receivers and PPM receivers. As for the benefits, I still don't know. . . . . .
2, flight control
Also called the flight control board, the brains of the aircraft (we got together to pray when the class time came. In fact, I also found it on the Internet, as explained in the following several units) . The role of the flight control is to quickly adjust the four-axis flight status by using the gyro on the flight control board (which is an instant matter, do not want to use human flesh). If there is no flight control board, the four-axis aircraft will be installed, Outside interference, inconsistent parts and other reasons form the unbalanced flight force, the consequence is that the left and right, up and down tumultuously, can not fly at all.
MR DRONE's flight control I asked Warwick's official WeChat, and got the response is Warlock's own research and development control: Model FCS-250 MR Drone, open with me to see what is open, is not yet known The difference between this flight control and the current mainstream open source flight control is yet to be further verified by players. However, unlike the flight control models that were tested before the release of the 5imx, the FCS-Runner 250X was the one they got. This TM is very embarrassing. Is it an upgrade or a downgrade?
MR DRONE's flight control has micro usb, which can be used to adjust parameters. Judging by my incomplete and correct experience, the F8 remote control still has five key channels like the AUX2-AUX6, and it should be able to be set to the key of the quick flight mode after adjustment, such as 3D. I was afraid that what I did was a one-time action. Then the plane said that it was in my hands.
3, ESC
The function of the ESC is to convert the control signal of the flight control board into the magnitude of the current to control the rotation speed of the motor.
Because the motor current is very large, usually when each motor works normally, there is an average current of about 3a. If there is no ESC, the flight control board can't bear such a large current (in addition, it doesn't drive the brushless motor). Features). At the same time, the ESC also acts as a transformer, changing the voltage of 11.1v to 5v to supply power to the flight control board.
MR DRONE's ESCs are modularly designed for quick release and maintenance. The connection method is still using a plug-in similar expansion screw design (the industry is called banana head, think of how much human brain hole), to ensure that will not be loose in the bomber, off. Praise for the fine design.
4, brushless motor
I can paddle without paddles. . . . . I can rely on waves for boating. . . .
However, drones cannot, not only paddles, but also brushless motors that drive the propellers. DR MRONE uses a brushless motor model WK-WS-28-014A, and the KV2500 provides DR MRONE with powerful power.
Although brushless motors have many advantages over brush motors, they cannot be used alone and must be used with ESCs.
5, camera
DR MRONE is equipped with a camera with a resolution of 800TVL
This looks like this. The back of the white reservation statement did not say what it was doing. Can it be installed? Think much more, through the machine mounted what Yuntai.
Support 1920×1080P/60FPS, think it should be enough to use on the plane. If you have to bring aerial photography, it should not be enough
The top left button is the switch between camera and video.
Micro SD card slot, but not inside the accessories, since it is already a finished machine, why not random a small card, 16G also ah. The manual only describes the use of high-speed card, consulted the Warcor Marketing Department, told the maximum support 32G card, but fortunately asked, or almost into the 64G
MR DRONE is equipped with a shock-absorbing mount for the camera, which acts more or less to suppress camera shake during flight.
The only concern for this camera is the location of this memory card, which day manual mode, interested in a high 3D flight, plus a large wind, to shake down what can be good, I have to take a metal detector full Go to the venue. Looks like this probability is still far away from me.
6, GPS and image transmission
The front-end GPS antenna uses the GPS+GLONASS dual-mode satellite positioning. It is fixed at a fixed point and is suitable for novices. But everything has a two-sided nature, GPS mode with a lot of manual mode is basically handicapped, so it is recommended that novices can use manual mode to use manual mode, at least manual mode with self-stabilization, to ensure that no half-day will be able to find a little touch ( Prerequisites to buy a few more batteries). Believe that the level is blown out, to see such a thick bracket, generally fried is not bad fried, playing through the machine is the pursuit of speed and passion (when Super 8 can be released)
Figure antenna
The image transmission chip below the antenna has a transmission distance of 500-800 meters. I opened it to watch the channel. As a result, I found out that the receiving channel is different from the transmitting channel (the transmitting frequency is 5733MHZ for 8 channels, and the receiving frequency is 5725MHZ for 9 channels. It is not clear whether the factory is like this or not. If you can start, you can check it.) This will be awkward. How can the finished machine be shipped without debugging? If you come back and find out that you don’t want to disassemble, you can also reserve
Fourth, remote control
The Warburger equipped with a DRVOONE is a DEVO-F8 remote controller with manual control mode, fixed-point setting, one-click return, camera control and other function switches
Non-slip rubber on both sides and back increases the feel. The overall texture is excellent
The three knobs and the two joysticks are made of metal. The damping of the knobs and buttons is moderate, but the feedback of the knobs in the following diagram is somewhat blurred. Below the remote control is the power display and the connection display of the mobile phone APP.
But the left stick of this remote control will be in the back, unlike the F7 which doesn't return to the middle of the function.
The top of the interface, USB interface is used to connect the MR box VCT02, the left and right two wheels are the control head, there is no role here
Different indication states when charging and after filling
The setting of the remote control fixed ID code is not described in this manual, nor does it tell us what to use. The outsider simply does not understand this ID code (well, I'm talking about myself).
Fixed ID setting: The setting of the self-defined ID code needs to be performed automatically when the code is received successfully. This eliminates the need to code every time.
Here we must pay attention to: after replacing the aircraft model, we must remember to clear the fixed ID in the aircraft receiver, so that both the remote control and the receiver are in the state of automatic switching, in order to successfully match.
The opening degree of the mobile phone/plate bracket is fully enough.
Stent's cell phone area small bracket.
The description of the remote controller on the original manual is not on the number with the entity, so I really do not understand, is it necessary to simplify the remote control after mass production? Can only contact Hua Kerr again, so that they send a copy of the instructions on the number. Here, we must add that the attitude of the company after sales is actually quite good. It may be that people are really busy and the response speed is not as rapid as passing through the plane.
Game box. Download APP on mobile phone or tablet, you can simulate the game, a high degree of reduction, basically able to master the flight in the game, the real flight is not to mention.
Receiving antenna for game box
After the mobile phone and tablet are installed, it is such a burden. When you can integrate into a remote control, life is comfortable.
Welcom MR DRONE support IOS APP has not yet been applied to the Apple application. I was contacted by the marketing department of Wakol to send it to me. However, to provide a UDID number for a mobile phone or tablet, it is possible that the APP in the R&D stage can only be used for similar signatures. Method to use special planes. After waiting for the shelves, everyone can do whatever they want.
A balanced charger for charging a 2S or 3S battery. When charging the battery, this balanced charger is a little hot, so the lower body temperature is measured.
I do not know that normal is not normal. When charging, people must not run away and send them out of danger.
An adaptable plug power adaptor can charge the game box and F8 remote control.
According to my observation, this should be a general 2D paddle, so this product can not do 3D special effects, wrong, 3D action.
However, manufacturers have given an adjustment data line. What does this mean? Can you achieve 3D?
Provides two 11.1V 2200mAh batteries and supports flight time of 8-11 minutes.
The red light flashes when charging, and the green light stays on after full charge.
(The opening scene of the APP is Dubai's Longji track)
Before writing in the APP, first understand what MR is.
When the AR (Augmented Reality Augmented Reality) and VR (Virtual Reality Virtual Reality) technologies have been blooming, Wahlker developed an MR (Mix Reality Mixed Reality): a further development of virtual reality technology introduced through virtual environments. The actual scene information sets up an interactive feedback information loop between the virtual world, the real world and the user to enhance the realism of the user experience. Therefore, MR technology includes the functions of AR and VR devices, but unfortunately, this time we are not testing Google4, so I can only stare at the phone screen.
Warburg, the first company in the drone industry to get involved in games and mixed reality, is clearly prepared. One of the highlights of MR DRONE is the combination of games and reality, eliminating the need for venue restrictions and the layout of the track to increase the fun of the exercises. In addition, MR DRONE can also set aside the aircraft and conduct simulated flight, which solves the embarrassing situation that bad weather cannot fly out and a battery can only fly for ten minutes. My mother no longer has to worry about charging for 2 hours and playing the machine for 10 minutes.
MR DRONE APP has two modes: MR mode and simulated flight
The MR mode is a game mode in the case of a real-operation drone
The MR model is divided into: traversing, collecting, fighting, and free-flighting video (this should be a picture transmission). In the MR mode, only the free-flight unit was used. The other three were to be played after I was skilled in the game mode. Otherwise, the two rings haven't run out of batteries.
The mode flight is divided into: crossing, collecting, fighting, custom checkpoints and Dubai crossing machine track. In the designated task is to complete the clearance. After all, I didn't even play in the first pass. It's not a matter of testing these things in half a few days. People are scarce (I’m still very good at finding the steps)
The game screen is still very delicate
There are many parameters can be adjusted, MR DRONE is currently the only simulator with a Chinese, and for flying white, it is not difficult to get started, do not have to make more adjustments to the parameters, to master the game's flying feel and Skills, in reality, can greatly reduce the probability of explosives.
I can't play well, just come to a few official online maps. I will work hard and fly well for a short time.
It's this way to go through the game
After a few days of simulation, there are only two manual and self-stabilizing modes in the game simulation, and there are only two perspectives: the FPV and the follow-up perspective.
Self-stabilizing mode is very easy to use, but it is not easy to get started. Every time I go through a turn with the GTR, I have to push my head, unless you can overcome this, otherwise you will never fly well.
The manual mode was the real lifting of the restraint. A flick of an aileron flew a roll and I did not know how it had flown before.
This 5.8G picture is a bit blurry and the big gods on the Internet say that this is not a solution. I always thought that the effect of the image transmission should be the same as the image produced by the camera. I can be too young.
However, there is still a problem that must be solved. The iphone and ipad will not be displayed in full screen (Apple series is like this, do not know if Android is also the case). This results in overlap of OSD information with the original screen information, and the reading is relatively strenuous. There is currently no way to adjust the video.
In fact, this screenshot is still close at rest, if it is to take off and then leave the distance, it can be described as bad (I don't know if the Google4 version will be better), from time to time the signal is disconnected, although only 1-2 seconds, but when crossing, this time is enough for you to blow up.
The instructions stated to avoid areas like mobile base stations that could interfere with the quality of the images.
Let's take a look at the content of the graphic transmission on the manual.
Why am I still having 60fps on it, and what is the logo like New Line Cinema on the edge? Can you get rid of it? Online, etc., very urgent.
This is the video capture screen quality that comes with the camera. Forget the garbage.
This is still a good look, do not zoom in.
Parameter Description Camera does not shrink
Seven, actual combatNote that this is no exercise.
After a brief review of the instructions, I rushed to the ground and it turned out that it was wrong. Be sure to read the instructions carefully before taking off.
Paddles are reversed, do not install wrong
Ensure that the aircraft's center of gravity is at the center point. 
This is very simple, but I tried several times without success. The reason is that after the remote control is turned on, I need to immediately connect to the power supply of the aircraft. I thought that when the remote control was completely self-checked and then the aircraft was powered on, the result was BB alarm. failure.
The final calibration of the compass is to be calibrated on the first flight or flight from the first remote place.
Do all the preparations, then you can fly with peace of mind.
There are a lot of trees on the lawn of the community. The first time it is less than one person, it does not know the northeast and southwest, and the result is directly hit the tree. Mom eggs, what makes the crowds of melons look at me? Afterwards, how can I eat on my face in the community? Am I wise to destroy this plane? Fortunately, the aircraft had a good ability to fight against the attack. The skin did not lose one piece. Forget it, or go home and get it done. As a result, without the help of GPS, I ran into the sofa directly and blew it up. Just like I was driving for the first time, I turned off 18 times a day. If it wasn’t for the coach to see me as a big man, I had to flatten me in the morning. But this time it was serious and broke the paddle only
Good meat hurts, there is no, so I have to come up with 82 years of beer to celebrate
I heard that beer is more suitable for explosives
Beginner friends, be sure to bring beer when you fly, and I promise you to use it. But do not fly after drinking, so easy to drink and drive, the taste of isolation from the world for 15 days is still uncomfortable, do not ask me how to know, I guess.
Find a suitable place to take off,
The flight posture is still very beautiful, although the front face is still like a squat, but it feels much better than the Runner250, which is a low altitude GPS hover shooting in the community, in a tree environment, GPS hovering is not very stable, satellite The number has reached 11. This feels a bit like self-stabilizing mode.
Therefore, please do not try to fly in a residential area. It is mainly unsafe and crowded. If you hit a hand, it would be bad if you hit someone. Even if you hit a tree, it hurts.
The fly test in the community's small intestine trails (this will focus on everyone's eyes, no matter if they are on the plane anyway). In fact, I can fly faster, but in order to shoot, I can only be unconditionally obedient. The operation response is still very sensitive, but the GPS mode seems to be useless, requiring constant manual correction of the angle. There may be trees above it that interfere with the signal. But this is more interesting than flying in an open space. At the moment I am chasing it to fly and create an FPV. Whoever tells him to pass on the image does not give it power. After that, I cut through the flight records and I cut it.
This is the low-level hovering in the community, or the GPS mode, or can not be fixed high, GPS is a signal, it is unlikely to be disturbed.
High altitude GPS hover (Hey, please tap the shooting technology, the weather is not very good), can clearly see that high altitude hover is very stable. This is a great help for novices. The manual mode can't be pulled directly to switch GPS. But it is not conducive to practicing flight technology.
This is a circle flight around the circle. From the first perspective, there seems to be no quasi-peripheral surround. It would be great if the camera could surround the reference point.
Shooting from the ground (patching pats gone, and later studying techniques for shooting).Everyone must be disappointed. How can I shoot such a video? In fact, I do not know how to do it. It's always difficult to get started and it's good to get used to it Now let’s take a look at the video of foreign cattle playing through the machine. This is the direction of my study. I must work toward this goal. Or just that sentence. When I am a student, I’m going to work hard. None of the papers have more words for this assessment.
Look at this flipping too fast, like a tornado. But he is the 210 machine
This guy will enjoy, in fact, most of the people are too suppress their own, and the other day I also took the MR to the seaside FPV, and then, small value, this is out of the sea warranty?Real fly to the last few pictures
In front of the painting, it's okay.
Eight, summary During these days of test flight, I gradually felt a little touched. From the GPS mode, I could go slowly toward the manual mode. (I was wrong. Actually, no matter how difficult it is, I also need to start training from the manual mode. I believe, but I don’t want to. Lose my money on the line), accustomed to the 2D plane control, now do not know the dimensions of the northeast and south, or like the control toy remote control car, a key in the end, it is not enough. Now mainly to learn to collect, just as human temper, restraint is the most difficult, but the rider is the same with the driver, and should have temper.
MR DRONE is definitely a good thing for beginners. Under GPS, no matter how you fly, you can't fry. Even in the manual mode, the rate of bombing is very low. Unskillful will only make the plane fly away. It will feel like it will not be able to pull off. It will correct the attitude of flying, and it will feel like ESP will intervene anytime and anywhere. Will not let you overturn. The analogy used in the car is the GPS mode: When the oil is taken off, it will automatically brake, and it is an emergency brake that is set in place. Manual mode: The oil will not brake, it will fly in accordance with inertia, which needs to be judged, FPV can be more intuitive, just like driving, but the problem here is that the map is really bad, hope Huake Can improve. So many times it is visually flying. Actually, visual flight is a master's job. So often do not know the direction in a few turns in the air.
But its positioning is a passing machine, I really do not understand it can not do 3D action, and Wacker's staff also made it clear that I can not fly 3D, is it positioned just a machine through the shape of the game? But the previous article also said that the image transmission effect is too bad, playing MR is simply looking for a crime, do not know if the late firmware upgrade can bring surprises.
Advantages: New industrial and modular design, beautiful appearance, excellent workmanship
Reasonable structure, drop resistance, easy to use, born for entry
The first simulator with Chinese language, the first to be embedded with MR mixed reality technology, so that the flight is no longer boring
Equipped with 5.8G real-time image transmission system and OSD system, equipped with 1080P/60FPS high-definition camera
When the aircraft loses the remote control signal, it will automatically return (GPS signal is normal)
When the aircraft power is low (below 10.8V) and the distance from the HOME point is more than 8 meters, the aircraft will automatically return. If it is less than 8 meters, the aircraft will descend from its current position and land.
Disadvantages: standard configuration without a package (this is a bit difficult to say, always can not pick up a box every time you go out)
As a passing machine can not fly 3D (hope that the parameters can be achieved)
5.8G real-time image transmission system
