20210314 The formal design of the project is completed. Submit the homework to the homework form. Junior high school students will go to school again tomorrow.

20210317 Project modification completed and PCB put into production

20210321 PCB arrives, motor propeller arrives

20210329 Official welding completed, test OK

The project ends here.

The test flight video and other information will be uploaded in a few days. The junior high school students are busy with their studies.

The 3D printed shell used this time:

-------------------------------------------------- --------------Dividing line---------------------------------- ----------------------------------

In this PCB 3D preview, the MCU is on the back and the IMU is on the front.

Next is the tutorial on flashing the program. It is a combination of text and pictures, and all attachments used will be uploaded, please use them as needed.

1. Short-circuit the download BOOT pin.

2. Use any USB-TTL download module to connect to the 4P interface of the flight controller ( please connect to this 4P port )

3. Open the Betafight parameter adjustment software (this software provides the Github official website, please support the original author)

https://github.com/betaflight/betaflight software official website

The first step is to program the firmware. (After each step is performed, it is recommended to save and restart the flight control)

The second step is to connect the flight controller and do basic debugging.

1. Calibrate IMU

2. Basic settings

3. Receiver settings

After the settings are completed, open the configuration interface and set as shown below.

4.Mode configuration

5. Motor test

(The propeller must be removed before testing!!!!!!!!! The propeller must be removed before testing!!!!!!!!! The propeller must be removed before testing!!!!!! !!!!)

At this point, all parameter adjustment work has been completed and the aircraft is ready to fly. If you want to pursue the ultimate flight effect, please study and debug the aircraft PID parameters by yourself. Please pay attention to safety during the debugging process and beware of injury!

Thanks to LCEDA LCSC HK and other manufacturers participating in this event for providing economic, technical and component support.

It gave me an additional social practice experience.

Thank you to all the hard-working staff.
