This project was started in November , 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). It would be cool to add more features to this project but I am pretty busy with my PhD research. But maybe one day I could combine my scientific interests with my hobby projects...

GEMiNi - first competition :)

We had a small multirotor-meeting here in Bremen last weekend, and there were also some people that were up for a FPV-competition. So the GEMiNi had its first opportunity to do what is was built for: Race!
A track was quickly built from chairs, tape and some other stuff we found. It was a lot of fun (well I could do FPV-competitions every day because I like it very much to fly "for a reason"), and the GEMiNi finished first.

See the video here:


  1. Congrats, you're the best!

  2. well explained.. thanks for sharing your thoughts..

  3. Very nice! Which OSD are you using?

    1. Hi, I am not using any OSD when flying the GEMiNi. It is not necessary as I don't fly far away, and I also don't have to time to read the display.

  4. Great flying!
    So, when can I order one? :-)

  5.
