As I was at the end of my high school, I wanted to learn about drones by building one. It was a lot of fun to build and to fly. I had to learn a lot about electronics and programming to make it work. The software is based on Betaflight.
The electronic part was the most challenging. I had to learn about ESC, motors, batteries, and a lot of other things. I also had to solder and properly use a multimeter, before having start my electronic studies.
I then took part in a competition with the association Anjou Drone Racer. Unfortunately, a soldering went wrong, it burnt and crashed. I still have to fix it.
Thanks to another pilot, I have been able to participate with its backup drone and ended up 9th over 14, here is the leaderboard
