This project was started in , electronics and control loops. Because I always need a cool project to learn new things, it was clear that something that can fly had to be built.
The project started as a "tricopter-only" project, but as I wanted to build smaller vehicles with more payload capacity, I decided to make some quadrotor, hexacopter and Y6 hexacopter firmwares too. My main interest is to build very small MAVs that fly as good as larger ones (or even better) and that can be controlled by wireless video link. I also experimented with autonomous flight in GPS-denied areas (video), and with GPS assisted autonomous hover (video).

125mm, 125g mini brushless copter

Currently, I love to fly with my latest design, called "RECOIL": It is a very small brushless copter (125mm MTM) with a total weight (including 3S 450 mAh lipo) of 125g. It however flies like a large copter and is a lot of fun!

  5. Drone races are becoming more and more popular nowadays. I personally attended one MultiGP drone racing in my home town. Drag race is my favorite drone race as I was racing with my Wife H107D X4 Mini which is perfect for beginners. I went to a MultiGP event and it was one of the best days of my life. Love to watch those machines racing. I would love to participate on these events, although I must exercise a bit more before racing. This should be fun.
