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).

Outdoor performance

Today, I recorded some outdoor scenes. Agility was improved, I think I should try a double-flip....


  1. William,
    Great work here! The most stable Y-copter I have seen. Thanks for posting at

  2. Very nice job ! As I do own already 2 mikrokopters (1 for fun flight with no option and an other for aerial photo/video and FPV), I am ery interrested to your tricopter.

    Results are quite nice !
