At the time of writing this article, only Warcor, a maker of fairly big manufacturers, had commodity-level crossings, and now Dajiang is about to release at the end of this month. Now the four axes of domestic model friends play mostly on Taobao. The aircraft model sellers assembled, some FPV are also assembled now, and nowadays most of the students in colleges and universities playing aeromodelling, doing thesis ah, program research, not popular enough.
This is before I played the four-axis F450,
You can look at my original tan
Here you can look at the next, I adjust the post-flight video, originally wanted to update that article, it is too lazy, coupled with more and more busy work, all 30 people, life is too stressful, no time to play. . . .
Because of the adjustment of MWC, but also transferred a lot of experience, there are new to the open source four-axis, do not buy MWC Cres V2.5 and V2.6 version, barometer is rubbish, we must buy GY86 integrated board, There are MWC + GPS module I transferred for a long time, but also add navigation board, I2C error more, all kinds of uncertain, and finally gave up, not much to say, are tears, in short, MWC Feifei just fine, do not Give him peripheral equipment, you can look at my original original, comment on his own lonely comment, mwc details, try to say all, if you have questions, you can read,
On video
The LED strip is 12V, and it was removed from the garbage bin that I used before.
The following video, you need to click the flip button
Starting from MWC, to the present APM, PIX, too much money, and now itching began to play through, through the main frame of the 250 210 180 wheelbase, this time I started from the second-hand, 380 yuan into the A 250 crossing includes
CC3D flight control + frame +3S ESC + Yinyan 12A ESC + some no-name D2204-2300KV motor +5.8G 200mw
After testing after purchase, the No. 1 motor responded too slowly. In the test process, not only the ESC was burned out (specifically, the 7805 element was energized and the big God in the group indicated that it could be repaired by oneself). Fu Si 9 received R9B also burned, the voltage regulator module breakdown, there are users welding their own, the next component is also welded, can only fly silk line, take the official, after the maintenance report financial know How much money, a few cents of the small components, Taobao 5 yuan shipping 50, how to bear their own poor welders, did not dare to weld, they entered the new.
In short, I hate to death, and spent 114 yuan to buy two receivers, spent 112 yuan to buy a positive turn of two motors + one ESC, and then their own poor welders, soldering iron power is too small, so that the seller to help The ESC motor was welded well and he bought 10 pairs of kinkong oars in his house. The paddles passing through the machine are flexible and do not need to be balanced. Therefore, they are also cheap.
After arrival, it was found that the screw was a 2.5mm Hexagon. Since the sister of me had been playing aeromodelling, the 3.0 of the 2.0 had no 2.5, and bought a set of 6 angles. . . .
According to incomplete statistics, I spent the money in open source flight control to buy a commodity four-axis. There are exchanges with other model friends, but also have their own buy, but open source has fun with open source, especially with the gods in the group to discuss In some cases, the occasional encounter with the big gods in the group was dug up by the big factories, and then closed the technology and put them out of the group. The fun of open source is that the planes of their own group, after numerous debugging nights, suddenly wanted to upgrade one day. However, after selling it and not willing to, after all, is hard to assemble and debug and can stabilize the sky, like their own children. . .
Say this through the machine 250, CC3D flight control is still relatively good debugging, a lot of online tutorials, the software is also user-friendly, there is a novice tutorial, follow the software step by step prompted to calibrate on the line, laughter between the wind, higher than his mother's MWC to not Knowing where to go, MWC also had to first flash the firmware for her mother, some low-pass filters, a sensor module, and even the throttle size must be adjusted in the program to continue to adjust the PID on the ground station. . . . With CC3D tuning, there are basically no errors or problems. MWC bursts out with various mistakes. . . . .
The CC3D motor sorts clockwise, unlike the MWC which is in diagonal order
However, after all, open source flight control has its own problems. For example, if the driver is installed, the system will prompt you that it has not been installed successfully. However, actually the flight controller and the computer are communicating. Therefore, once the driver is installed, do not even connect the flight controller to open the ground first. Station software, and other software start-up, even in the flight control, while suggesting that your driver is not installed correctly, but pay attention to see the lower right corner of the RX TX data, is moving, indicating that the communication
After finishing all kinds of adjustments with the software, it was found that the No. 1 motor still responded very slowly, so the previous original motor ESC was good and was broken by me. . . , Contact the seller to reply may be like this
However, once it took off, it was found that the slow response of No. 1 motor did not affect the flight, because after the take-off speed was reached, the No. 1 motor could immediately follow. . . Later, it was plagued by small mosquitoes on the standby stand. Later, it was discovered that turning on the LED switch on the distribution board had no mosquitoes. Yinyan 12A ESCs is difficult to adjust with a remote control, plus I could not tell the rhythm of the five-tone tone. I have always used the default. . .
All default CC3D parameters can fly, unlike MWC's default is a joke.
Figure heat is too hot, a few seconds after the power supply is hot, 5.8G 200mw Consider installing a cooling fan later
This is the way it is done after all the assembly adjustments are completed. A foam plate is added for shock absorption, and a direct tie is tied to the rubber. . . . It is still a cable tie, and, the cable tie is also cheap, online 9.9 bags can not be used up. . . 
Last Last Family Portrait
Coming through the machine 250 indoor test video
The first time I was flying, I was really sensitive. I would respond if the remote control rocker was moving. . . . .
Then encountered a problem, the 1st motor response is still somewhat slow, but does not affect the fly, some left deviation after take-off, but because the passing machine is too sensitive, you can instantaneously rest positive, there is the 2300KV motor, is not the reason for high motor speed , causing a momentary discharge of the battery is a bit large, when the fly BB always alarm in advance, and then display 4.0V after landing, there is no alarm voltage, fly F450 1000kv motor, there is no such problem,
Another problem is that Yinyan 12A has a large amount of heat, and flying for a minute or two is a little hot, and it is as hot as the image. . . .
After two days of receiving the FPV screen +5.8G R832, ​​more videos will be placed in the comment area.
If you think I'm flying bad, you can go to the video site to search through the video abroad, a variety of fine incentives and fried chicken. . . . .
When a junction box is used for every electrical connection in a building it is much easier to locate and repair any electrical problems that come up.
When some connections are made without junction boxes, such as inside wall cavities or in hidden ceiling or attic locations, the likelihood future problems increases.
Every electrical connection should be inside a protective box that is easy to find and access.
