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).

GEMiNi, frame + canopy

Here are two images of the current status. Green is the favorite colour of my girlfriend ;-) . There will soon be an additional one in purple I fear...


  1. Wow look´s very nice. From witch material is the frame?
    will it be open source or do you wanna sell it?

  2. The frame is made of 5mm cross grained balsa and 0.5mm glass fibre sheets. I am currently in discussion about commercialising it.

  3. wo w, really beautiful! sell the kit or is it just a prototype ?

  4. would definitely be in on one of these! Beautiful work!
