Ultimately save money, money, money, articles, four: 240 yuan to take you four axis model entry and fly to the sky

The toy-level four-axis is not discussed here. In the previous two days, a certain fish flower 240 received a set of F450 racks + 4 yellow tandem ESCs + 4 XXD 1000KV motors. The seller sent an additional MWC flight controller to use the original one. Fushi 9 flight controller bought when playing fixed wing, did not brush machine. , So he went to no return, PS. The more money you save, the more you spend.

Before I arrived, I searched the Internet for information, racks, and motor installations. I didn't have to say that anyone who would use the last screw would be too difficult to control the MWC flight control because MWC is an open-source flight controller. The IMU boards are not the same, and the tutorials are not the same. Even if it is the same, because of your rack specifications, motor specifications, MWC parameters are not the same, which can hurt my little white, fortunately added A few groups, there is a mode of friendly guidance, or can not be unlocked until now, because the information left by the aircraft model forums are too old, so here to make it easy to understand, do not speak highly, first safe to fly to the sky Besides, with a certain sense of accomplishment, you are exploring yourself.

Receive a list of accessories and install the rack first.

It should be noted here that the bottom of my small factory out of the rack is not a circuit gold plate. Most of them may be welded directly to the lower gold plate. Mys is not. I use a line directly. Paralleling, such benefits can be used without welding, the disadvantage is also obvious, too many lines, it is not easy to organize.

The connection mode is very simple. The motor is connected to the motor and then the signal line is connected to the flight controller. The remote receiver line is connected to the flight controller. The flight controller is the entire control center.

However, before installation, it is recommended to write procedures in the MWC program. The latest MWC program is 2.4 download address here MULTIWII GUI debugging software, this software requires JAVA support, according to your computer configuration, this will be said later,

Then download Arduino. When I was down, the latest version was version 1.6.9.

Then, JAVA arduino two need to be installed, installed, select the line ardunino, click on the file --- open MWC program, here to find config.h only modify this document, here to note that other online tutorials to be modified A lot, because they have other sensors such as GPS ultrasonics, and mine does not, so there are few modifications, so that when compiling, there are fewer mistakes.

The first place, modify

Throttle equivalent can now remain the default, no need to modify I2CSPEED 1000000L 4000000L no difference, casually

Some of the filter frequency 98HZ selected some 42HZ, note that the 2.4 program version is what ITG MPU6050 like before, where GYRO, is a common meaning, that is, you set the frequency, the program will be based on your motherboard is kind Sensors, automatic selection,

My MWC flight controller is this specification,

This time IMU integrated board selected GY_86 some tutorials will be selected FREEEMUV043 Although the motherboard quants is also the same, but I tried, I can only GY86, this, do not understand why. . .

In the new MWC2.4 program, there is another mutiwii.h to be changed, that is MAXCHECK this default is 1900, in the previous version of the mutiwii first document, here to pay attention, I changed to 1850, this One step must be changed because most newcomers can't unlock it, which is why they haven't changed here.

After all these changes, you can upload the program. Then go to the GUI this step

Select the COM port, and then point start your flight control even connected, this time, you can also connect your receiver, you can try unlocking with the remote control, throttle and other operations, can be displayed in real time to this program In this case, it is necessary to ensure that the pitch roll yaw three controls are equivalent to about 1500 in the middle. If the difference is too far, you can use the fine-tuning button on the remote control to adjust.

About unlocking, the throttle is usually hit right down, and when the throttle is locked, the arm turns left, and after unlocking, the ARM turns green, and the flight control board is blue and steady. Conversely, it turns red and the blue light goes out. Only the ACC MAG calibration is performed, and then the ANGEL All of the self-stabilizing point is white, because I haven't learned three-step switch mixing control setting, so the default is to turn on self-stabilization, after the calibration point write. Then, check the direction of the motor, turn it on, and you're ready to fly.

When you fly again, be sure to pay attention to safety

The aeromodelling hobby is endless and correct manipulation is the key. Do not use equipment as toys and ignore safety for a lifetime.
Novices are good to practice and practice, and do not show off while away from the crowd. Friends of the world model friends, build a beautiful new life together.

At this time, you will find all sorts of problems. Don't worry. You just started. Hahahaha, the accelerator hasn't been calibrated yet. PID hasn't been tuned yet. Hahaha, what do I say, save money? The more you spend money, you fly a MWC, you have a kind of urge to take it, spend more money on a stable flight control, and, under Amway, the two days of DJI flight control NAZA+GPS package engage in activities as long as 499, this flight control is more simple and worry-free, the main station pushes


So I found that playing aeromodelling, hardware is now worthless, a family workshop in the coastal area of ​​Guangdong, a minute to give you a full set, Dajiang's algorithm is too valuable, after all, not everyone is adjusted + code + DIY master


PS. Other flight control such as KK QQ APM flow is not discussed, after all, is the entry article, I also heard that the rabbit flying control author was dug by a big factory, so now a treasure can not be found? ? ?
