I also clearly remember that in September last year, Auntie had fortunately made my most fortuitous visit. I measured a Warburg Racing UAV. At that time, my concept of a drone still remained on the Dragonair. Self-examination, I didn't know anything about passing machines. Aunt made me come to me (thanks to Aunt's affection), so I completely wrote this testimonial as a little white person. Of course, afterwards, this machine can't fly through the plane at all, and he can't fly through the fly. There are GPS passing machines that should be picked up by newcomers.
Into the attack, retreat can keep, to fight the value I have enough - Warhawk mixed reality MR DRONE drone flight test - value friend evaluation _ what is worth buying can be attacked, retreat can keep, to fight the value of me Also enough - Warhawk mixed reality MR DRONE drone test flight, what is worth buying the product of the public platform, provided by the Guangzhou Hua Kerr Technology Co., Ltd. to the value of the trial, the total number of 2, welcome to like this product The value of the Friends of the application for trial and provide assessment experience article. Test.smzdm.com to see Actually, this plane may have problems like this because of its design. I returned to N factories. From the beginning to the end of life, I gradually learned a lot of knowledge, and realized that all masters are The reason for the group to cross the plane by yourself is very simple. The first group is economically affordable. The second bomber is easy to maintain and cheap. The third energy security needs self-organization (high performance), and the fourth fun is a lot.
After visiting various forums and adding more than one group to the group, I had the idea of ​​owning one group (this is absolutely the pit that the aunt took me into, and the aunt you are responsible for), because the foundation of 0, the forum to see the tutorial Do not know where to look, is completely jumping to see, and then slowly comb their own, while also familiar face in the group, dragged after people are familiar with the question, most people know that as long as there is time to be more patient to help me, Of course, there are others who ignore me. Slowly watching other people's videos, looking at the foreign God's FREESTYLE, their own will to fly more strongly, I clearly remember the first to buy the accessories is a rack, until the purchase of the last accessories camera, a shared six months time . Buy parts to buy for six months, ah, you Big Brother, how poor I was, one month, the speed of a accessories ah. Forget it, think about a better future.
Turning over the aunt's home, all of them are aerial drones such as Sunda, Xiaomi, and Zero. If the self-assembly hasn't sunburned yet, we must start the sun and get excited.

After the above parts group can fly. Of course, for beauty, practicality, you have to buy some additional accessories: a variety of wire, heat shrinkable tubing, screws, nylon columns, double-sided adhesive tape, cable ties, battery straps, etc., anyway, novice Buying Qi is basically impossible. There is a messy motor protection cover and an electrical protective cover. In the later period, we must add dogs (cameras, you and my favorite). In the future, you will have to buy more things.
If there are many tools at home, you can use them. If the tools are not matched, you have to buy them. Like soldering station, soldering wire, solder sucker, allen screw driver (this can not be saved, will be mentioned later), small-angle oblique pliers, etc., buy buy buy, since you want to practice your own hands-on ability from the beginning, you can give up halfway.
Installed
Here first talk about the rack, the general through the machine frame is 4-axis, QAV, positive X, box, low center of gravity, shaped, of course, QAV rack is the most (we are interested can check it out, I'm here Not on the table), is also the easiest to install, space is great. Why did I choose a positive X-Rack? At the time, my heart thought like this: It was difficult to get started, and you could not leave yourself behind.
Buy a bunch of auxiliary materials, a lot of useless, first prepared, motor protection can not be, my hand, to maintain the cost of maintenance, or use it. The ESC protective cover is recommended for everyone to use, you can buy your favorite look, or you can use a broken paddle to tie it, and the paddle will hit the ESC.
The space in the middle of the rack is relatively small, which is the difficulty of the installation (of course, if the distribution board, the ESC, and the image transmission are integrated, it is much simpler, but I still like to split, the higher the integration, The easier it is to break, the worse the cost is still higher. I think so, there is something wrong to welcome me.) The first time I had to challenge, it was good. Positive X-Rack 4 arms are X-shaped, easy to operate, more flexible, suitable for the track. Actually, I didn't even think about racing. I just wanted to fly freestyle. It was enough. I bought planes. Of course I chose what I liked. Actually, I prefer chameleons and suffer too much from the price of 95 knives. Only far away can not play near. Pull away.
There must be a skill before the machine is installed, otherwise it will damage a lot of things, that is, electric iron, the first is the choice of iron, playing aeromodelling there is a sentence: Do not save money, save money is the beginning of money. The meaning of course does not mean that you only buy expensive ones. Before you buy, you can first ask the old friends in the forum group, compare the recommendations of them, and then choose one from them. Basically you can't go wrong. Some things are still wrong. Unexpected unanimity, this is the accumulation of experience, so that novices less detours.
Well, the selection of soldering iron is generally the selection of constant temperature soldering station, this thing is often used, buy a good point can not be wrong, domestic yellow soldering station, such as Japan imported white soldering station, are more easy to use. We recommend soldering stations for soldering circuit boards such as those for flying controls. There is no place for soldering stations to prevent electrostatic breakdown. Again, the power is at least 60W when selected. Japanese white light I do not link, too much white light in Shenzhen, Japanese white light called hakko, are more than 600, Shenzhen Baiguang block. You make your own decision.

Unfortunately, the landlord did not choose a Shenzhen white light to save money (no money at all). A group of heads are sent, which are available in all sizes. They are suitable for various occasions and are generally adequate for families.
I thought that the small holes of the flight controller were more ideal with the tip, but after actual operation, I still like this horseshoe head. It's easy to take it all together. It's quite convenient for me to use it anyway.
After the soldering station is set, it is the choice of the tin wire. Now that the general tin wire contains rosin, it will be easier to operate. I figure is convenient, did not study carefully, packed a roll with the soldering station, it turns out that I was wrong again, the melting point is not high, and there is no metallic luster, it looks really not the general ugly
This is it. It hurt me to lose a general. 
This is a piece of electrical board that was soldered to waste. I took him to practice. The above row is very full, crystal clear is the new buy, the following are all poor tin wire, the contrast is obvious. Saying that the quality of the board is really nothing to say, the pad has not fallen off after heating for a long time.
So I can only buy it again. The veteran advised me to buy Yamazaki. The melting point is low, 183 degrees, and the ratio of tin to lead is 63:37. The degree of handling is completely different.
Compared with the two, the appearance alone can not see the name of a celebrity, it must be used to know, ah, have a deep understanding.
Matek PDB-XT60_Taobao search s.taobao.com to see 
Hogan Lotto XRotor Micro BLHeli-s 30A DShot 600/300/150_ Taobao search s.taobao.com to see Such as textbook-like solder joints. Before the machine is installed, the motor is welded well with the ESC (the ESC requires a heat shrink tube), and the XT60 female connector on the distributor board is welded well. All the wire and the pad must first be tinned. All the wire and the pad must be tinned first. All the tints and pads should be tinned first. All the tints and pads should be tinned first. I said it all four times.
F3 roughly the wiring diagram is like this, it does not seem very difficult, but the assembly will find that not all things are developing in accordance with the ideal, such as the receiver, although the SBUS protocol to connect only 3 lines is very simple, but frsky xsr To achieve data transmission must also be connected to the s.port, and this interface is DuPont interface, so get line, so all product wiring must see the instructions or wiring diagram, otherwise, there is no signal light, then re buy a piece. In any case, the entire aircraft is in the hands of the examination ability, and refusal of the line is not difficult.
The strip is put on first, and it is not easy to operate the space after installing the distribution board. 
The carbon plate of the rack can't be directly affixed to the distribution board, and it will be short-circuited. Generally, it is isolated with a nylon column. There is no way to do this, and insulation must be done.
Cut off the long line and leave a little margin for it. A large pad around the Matek PDB-XT60 distribution board is connected to the power line of the ESC. Below the middle small pad: 5V is connected to the flight controller, 12V is connected to the map, the VBAT of the VCC is controlled by the VCC. To measure the battery voltage for the flight controller.
Welding here is not so textbook.
F3 flight control _ Taobao search s.taobao.com to see The flight control I selected was the F3 basic model, deluxe (deluxe version) increased barometric altimeter and electronic compass direction Sensor, after all, flying through to the barometer is useless. However, F3's main control chip STM32F303CCT6 storage capacity of 256K, some black-hearted merchants replaced by STM32F303CBT6, storage capacity of 128K. But in the final analysis are open source flight control, these are domestic imitation, genuine hard to buy.
The above is the F3 flight control wiring diagram, different flight control has different wiring methods, but it is only a different location, but it has a name tag above, although it is F3's world, but F4, kiss and other flight control prices dropped significantly. It will take less time for F3 to take off tomorrow. After all, this thing is too fast for electronic products. This has also benefited from foreign sources of open source, or else they all registered and prices doubled in minutes.
The flight control is directional. The arrow in the figure is the direction of flight control. After connecting to the ground station, it will be displayed on the ground station. The figure below is the nose. Sometimes the USB port will be arranged on the right side for convenience of adjustment. The direction of flight control is inconsistent with the direction of the nose. It does not matter. The ground station can be modified. However, nowadays, all parameters can be adjusted by mobile phone.
LED lights take power at the 8th pad (except 12345, can take power, here is the voltage of 5V, the same pad do not weld two lines, with the exception of VBAT), I did not weld all LED lines, this LED light Integrated BB ring, I only received three lines (positive and negative and BUZZER positive, even the cathode are too lazy to connect), to achieve light, will be called, the other two lines is to adjust the LED parameters for remote control or flight control, anyway There are buttons to adjust, I will save trouble.
Basically completed, pre-arranged space locations and alignment, it is OK, too long line is best screwed up and stuffed in the plane, do not expose, only the bomber interrupted, then only one way. If you have forcing cards and like to take a back line like a computer host, you have to plan it.

AOMWAY Omron TX001_Taobao search Taobao search is the most intelligent commodity search engine, through the operation of big data, accurate understanding of goods and users, providing accurate personalized search experience. S.taobao.com to see The camera is relatively simple, and it can be plugged directly into the Dupont connector. It is so rude that the picture is connected to a 12V power supply, and the camera transmits electricity from the picture. But you have to look at the instructions first, and the order of connectors is the same. Be careful.
Here is the choice of runcam swift2, pay attention to night flight can choose runcam eagle, and now eagle2 generation also came out, the price dropped really fast. Of course, there are many other options, generally more than 600 lines OK, through the use of analog signals, low latency, can not be used as high-definition digital map transmission, so you use a 4K camera is also a waste.
There is a certain amount of emphasis on image transmission. One person plays, and the innovation department is also good. The price is still low. However, if the number of people is large, his interference will be more severe. The moment of starting will cause others to receive your signal. Fast speed, I didn't know where to fly after 2 seconds. Therefore, in the past, if a model friend wants to install a new camera, he will call the audience and let other people prepare. . . . . . The best known is the black sheep. I have no money, I can't afford it, and the price can be a little different. Of course, last year's Israeli developer Amimon introduced a zero-delay CONNEX ProSight HD Vision Kit HD digital image transmission, the 720P30, this year also launched a CONNEX ProSight, control within 90MS, basically do not feel the delay, that no delay is Manufacturers exaggerated claims. But the price, in fact, is also good, a full set of price of 499 knives, equivalent to 4000 yuan RMB, lost too much pain only a few years only, mainly when many people fly also does not interfere with each other, you deserve to have.
At this time, it is necessary to test whether it can be installed or not. Check before power on, and then set the frequency on the control panel (usually the first is to open the control. Press and hold the F/S button on the receiver to release it. The red light will be off, the green light will be on, and the next time you turn on the power automatically. Then set the picture transmission power size, set the channel to see if there is no signal or something, no problem, the next step, the total installed. Otherwise, after loading the machine to try these, even if you do not even press the button.
Positive X rack space is too small, the picture can only be used to paste 3M glue on the board, the last remaining receiver, no way, or 3M glue directly on the flight control, installed on the board, the map is just pressure pressure Live receiver, perfect. All the lines are in the rack.
carry out. The battery of the positive X-frame is basically in the middle of the hanging, keeping the center of gravity down while keeping the center of gravity in the middle. Before the power is turned on, everything is checked again. If it burns, it will hurt self-confidence.
Empty machine 342G, plus the battery just 500G, this is not a Virgo for me, there is a kind of inexplicable darkness.
After some hard work, the installation was successful. It was still a sense of pride. After all, it was the first installation. But there is a saying called, oh yes,
If a worker wants to do good, he must first sharpen his tools. This is what the person who read the book said. However, the antenna of the receiver is so exposed to the soft fruit that it is broken, and it breaks when it is blown two times.
To start with the article, the Allen key must be present.
Generally, 2.0 is used. If there are many things, prepare 1.5 and 2.5 more. To use this HSS, hard enough, absolutely not slippery, of course, with the screw is better, generally with Fang Sheng.
In the beginning, I used this to install the machine. If there is anything at home, don't waste it. result
It was screwed.
I tried to remember it because I didn't want to remember it for too long. I bought a screwdriver directly online, causing me to delay for another few days.
Well, when the plane is over, it's time to talk about the three big things that go through the machine: the remote control, the FPV glasses, and the charger.
The remote controllers are generally selected from the four major series, Futaaba, Horizon, Ruikai, and Flowserve. They choose according to the budget. Of course, there are alternative small controls, such as evolution, TBS black sheep tango, you have to walk away from the bias is also very personal. The landlord chose a popular FRSKY X9D PLUS, he also does not need a SE version of the Mensao not to ask for a large base is also convenient.
Speaking of this X9D PLUS, it is also an open-source system, openTX, which can control the performance of the 1,000- to 4,000-yuan class. I can play for a year just by playing the remote control. Although it is made in China, but it is mainly in the foreign market, so,,,,,, no Chinese, but the majority of very caring model friends produced a Chinese voice package, when the alarm reminded more intuitive. Hey, you don't have to look for it. There is no Lin Chi-ling version, because when she finishes talking about the plane, she doesn't know where it went. So don't worry, you can read it for a few days.
The setting of the remote control will not be expanded here. It is too complicated, and it can't be said all day and night. The amount of this remote control is still very large. It is called the civilian Ferrari, so the online related tutorials are also a lot, what to look for, and where not Where will it be? There is only one point here. Please set up a loss of control protection at the remote control. The loss of control of the passing machine may not be the same as the automatic return of the aerial camera. We directly cut off the power, so once we get out of control, we can fall freely and never give anybody trouble. Why is it set up on the remote side and not on the flight control side, because the flight control's working environment is relatively worse than the remote control. Sometimes pumping and flying is also the machine's normal condition.

charger. At first, I wanted to buy B6. Is it economical? But when I saw news that it was charging, it exploded. I was scared to replace it directly with the ISDT Sc608 Balance Charge, and I had to buy a balance charger anyway, both for the battery and the airplane. Generally speaking, charging 2C or less will not be a bad battery (1C refers to the way in which the rechargeable battery is (possibly) continuously discharged for one hour in terms of the nominal capacity of the battery. 1 is usually the override, and C is the capacity. The commonly used pass-through battery is 1300MAH, 1C=1300MA=1.3A current to charge), completed in 20 minutes, this is the first time I think that charging can be so fast, to know that I measured the one Huake charge a battery It takes more than 3 hours and then 10 minutes to play. Of course, many are using the ISDT Sc608 as an outfield charger. I'm not the same. I'm home.
Later I got to know that the reason for the B6 charge explosion was because I used and charged the board. I was disgusted with using this thing because the first is not the original factory part. The second, the remaining power of each of your batteries cannot be exactly the same, but you use it. The same current to charge them will cause the fully charged battery to discharge again to charge the battery that is not fully charged. This is not good for the balance of the battery, and it is not safe to shorten the battery life. I still honestly piece by piece. People can't leave when charging, just in case.
Isdt sc-608_Taobao search s.taobao.com to see Glasses, why did I finally say it, because I didn't buy it at all, it's too expensive. Basically everyone who plays this game is using FAT SHARK or Skyzone. The former is more than 3,000, the latter is more than 2000, and of course there are hundreds of cheap ones, but Well, the bargains are too big, and they are stupid. Believe me, it will take you a long time before you change your grade. So I'm not going to be in the first place to cross the novice, and not to waste money to enter, and bought an FPV display - Eagle Eye Vision Ultimate.
7-inch screen hanging on the remote control is a bit heavy, must use a lanyard sleeve around the neck, many people use a tripod, I also use when convenient. Double receiving +dvr is enough for me.

Now passing through the machine to use the BF (Betaflight - Configurator) has been updated to version 3.2.1. It's almost like a fool. The installation method is not detailed, first use Chrome scientific Internet access, add Betaflight - Configurator in the extension program on the line. Will not go online to find the offline version of science, drag into the extension program.
Generally no accident, then you can directly open the Bahrain, the connection may not be the driving problem
CP210x drivers and STM USB VCP Drivers can be installed on both drives.
The first thing to do after all is to update the flight controller's firmware, you can see I'm now in version 3.1.7. Method is to select the appropriate flight control, do not select the wrong, and then he will find the firmware, these are scientific under the premise of the Internet, if not, then only download the ground station, find an offline hex file as shown below
Here are the different flight controller 3.1.7 firmware. Extract the local installation. Click on the brush when done.
Brushing the firmware is like installing the system. After setting up the brush, the things you set up on the ground station must be set up again. I hope you have not forgotten what you set up before.
Completed, point in the upper right corner connect 
The main interface, the plane of the aircraft is linked to your plane
Port, UART1 cannot be turned off, UART1 cannot be turned off, UART1 cannot be turned off, say 3 times. Anyway, you will regret it. Since I have smart.port, the telnettey output under UART2 selects mart.port and then opens UART3's Serial rx.
Configuration configuration items to be set up, as shown in the above figure the motor stop, after unlocking does not open the motor, is not open idling, but I opened the airmode, after unlocking the motor or will move. Open airmode is entirely for the ability to air. Because the ESC supports DSHOT, so I also open to the maximum, F3 maximum also supports the DSHOT600 (Dshot, oneshot, shot125 what is the agreement of the ESC. Anzhao KZ is much more to say that Dshot is a kind of flight control and electricity The digital communication protocol between the tuning, which was developed by Felix of Flydrino (which is the company that makes kiss-controlled ESCs) and Boris, the Betaflight team, and Steffen of BLheli is also responsible for the part of ESC and introduced this protocol to BLs. In short, these people understand the passing machine and know what players need, so they keep on innovating and acting as the leader. It's time for the plane to fly more and more smoothly.) The following motor idle is the idle speed, which is the airspeed idle speed value. Generally unlocking the idle speed value is used to unlock the idle speed value. If the airspeed idle speed value is high, the idle speed value of the airmode is used. Whoever uses the high speed is used. I have turned on the motor stop here. I just unlocked the idle speed and can only call the airmode idle speed. Is it a roundabout, I am dizzy myself.
YAW degrees write -90, because the flight control direction is -90 degrees when installed, tune back on it. The receiver can select SBUS (what do you choose?).
The first four are not set by default. Other switches must first set the channel map in the remote control, and can be changed and increased or decreased at will. For example, map AUX1 to A switch.
The switch map of the previous step is for the function of this step. Set the switch, click add range, select the channel, such as the first function switch ARM to AUX1, is to use A switch to achieve, toggle A switch, progress bar (You can freely set the effective area.) The red dot below will move left and right. When moved to the zone you set, the function will be activated. This ARM switch is a function to unlock with a channel. Now I'm used to unlock the channel, because it will be executed immediately, and there will be a 2 second delay when the lever is unlocked. The following function setting method is the same, the firmware rises to 3.2.0, many functions are very user-friendly, the former masters must practice for a long time, and now White can easily complete.
Others such as PID, I choose the default. Tuning PID is a tedious process. The three linkages, even if the same rack configuration, PID is not the same, but also varies from person to person, for him is a sticky aircraft, intact You may not fly well. My newcomer obviously could not keep up with this rhythm and waited until he could fly. If you start speaking, you can write another post.
Electric adjustment software
Electrical adjustment software: BLHelisuite, this is relatively simple, do not need science online, after installation can be used
First of all, select the corresponding COM port (COM port you use which is also used here), as I here is COM3. Click on the connect link. The security point will be followed by a step-by-step backup of the original data. This is generally not so mild. Click on the select ATMEL/SILABS interface item above, select SILABS BLHeli Bootloader (Cleanflight), then click CHECK,
Just jump out of the picture. Display the ESC version and other information, click OK. If it is not recognized correctly, you can follow the steps below: 1 Close the program, 2 Power off, 3 Off USB, 4 Power on, 5 USB, 6 Open the software, you should be able to All identified.
Click Flash BLHeli to select the version. If the software can recognize the ESC information before the software, the program will call up the latest firmware.
As marked above, my current version is 16.5, now 16.6, click OK
Before the brush will pop up a warning dialog box, what is the risk of the brush and the like, boldly YES.
After the progress bar reads, the display is successful (soon, basically an electric brush takes about 10 seconds or so). This is just a brushing of an electric tone. (Electric tone 1 forgot to take a screenshot, this is 2 and the careful partner should It's seen, then all the way OK and YES go, all 4
Updated to 16.6
After the BLS, many functions of the ESC are turned on by default, such as the brake is turned on by default. The biggest adjustment here is the motor direction. In the figure above, this ESC 1 is set to reverse direction. After the BLS, the ESC can control the motor steering. Instead of replacing any two wires in the same order as before, it can be re-welded, which makes it troublesome to look beyond the wiring. How is it now comfortable how to weld, and then come here to change direction. After the change, everything else is acquiesced. I'm very clear about it. Finally, point "Wite Setup" after all settings have been changed. There are many tutorials online for reference. The tuning of the ESC is relatively simple. Note that there are some differences with the ground. You need to connect the battery. You do not understand the welcome message. There is a question and answer. I will open a section called “Looking at the Manny Husbandâ€.
At this point, the plane should fly without any problems.
Finally, please remember this website, as an aeromodelling enthusiast, we must abide by laws and regulations, go here to register, although the website is very bad, registration can not forget
Test flight
Visually flying around, no problem, so excited, I feel too obedient to roll over and down, and why, visually, I forgot to bring the screen. As a result, I flew three flights of electricity and I was boring.
For a day, intermittent FPV, the result is not the same as I think, although BF has evolved to be very foolish, but with the default parameters to fly, feel is still jerky, sticky, even my beginners are Can feel it, of course, this is nonsense, it can be felt by individuals. So many planes that are arranged and grouped together want to deal with a set of parameters. God can't do it either. It can only be adjusted slowly. Fortunately, with the owner of a good relationship, because the same rack, to copy his parameters to fly, suddenly felt a difference, I first adapt to a period of time, and then slowly adjust my own PID, this is a long process.
In order to reduce unnecessary losses, the new machine is not on the dog in the early stage (no sports camera), so feel familiar, grasp the feel, and then take a satisfactory video. For the first group aircraft, if you don't write well, please ask more than Hai Han. If there is an inconsistency, please correct it in the comment area.
In the end, we must not fly in crowded places, near airports, or in crowded urban centers. Manual mode through the machine is difficult, it is recommended to use the simulator to familiarize with feelings, such as Freerider, liftoff, etc., are relatively well-known abroad, but the interface is in English, of course, Hua Kerr also out of paragraph mode MR DRONE, I heard Well done, mainly in Chinese.The first time the novice assembled the pass machine, but fortunately my ability is not bad, and I managed to get together. There are many places to learn and communicate. If you want to fly easily, you will have to practice for a long time. The old birds all say that the technology is blown out. This is true, it is loaded, it is flying, it is bombed, it is repaired, and it is repaired. This cycle makes it interesting to pass through, and it is just so that it attracts me to install a second machine. Beginners enter the pit and give advice.
