How to self-assemble a five-inch crossing machine from zero foundation

So I checked the relevant materials and videos of FPV again, and realized that FPV is not just the kind of crossing machine I thought before, but there is a hole in it. The following is my understanding of FPV: compared with consumer drones, such as the well-known DJI mini4K and DJI mavic3 pro, the crossing machine is faster (the speed of a 5-inch crossing machine is usually around 200km/h) and the entry threshold is higher. It has no autonomous hovering module and obstacle avoidance function, but it is precisely because of its high speed that you can see a novel perspective as long as you install a wide-angle lens with flying glasses. Not only that, most FPV players assemble various accessories into the pit by themselves and can design their own crossing machine according to their own ideas, which greatly increases the playability of FPV. So, I planted a seed of flying FPV in my heart, looking forward to one day being able to fly through the sky by remote control.

After the final week and most of the winter vacation, I made up my mind to assemble my own crossing machine, but I was worried that there were only a few days left in the winter vacation and I couldn't finish this small project, so I bought a remote control with Bluetooth connection computer and frequency connection physical plane, that is, RadioMaster Pocket remote control ELRS version. My remote control was American, and the throttle didn't return. I also bought a simulator TRYP FPV on steam. After that, I practiced flying on the simulator. Because I didn't find a systematic practice tutorial on the Internet, I had to learn flying by myself. At first, I was really dizzy, and I didn't understand the function of each rocker. Fortunately, I brushed the remote control calibration tutorial to understand the function of each rocker, and then I practiced it. Fortunately, the map in TRYP FPV was large and many, and I was able to choose sports to practice with the racket. So I spent the last winter vacation in this game. When you practice the simulator, you don't have to learn all kinds of flying movements, but you must learn to take off, hover, control altitude and land. These are very necessary.
