This project was started in November 2008. The goal was to learn something about programming, 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...

CFK chassis...

Probably, you already know the CFK chassis I am using on my personal Shrediquette. The chassis is really light, and I like the look a lot. While the chassis I am using was cut by hand using a jigsaw, now there seems to be a much easier way to get a chassis like this:
Max from California contacted me some days ago, and has the possibilities to make some sets of my chassis from carbon. If you are interested, please feel free to contact Max:
maximus365@@@juno.com



I made a rendering to show the two different sizes that I designed. I am planning to order the mini chassis, because I am currently making a mini-Shrediquette (153mm distance between motors).

Sizes of the chassis':
Mini: 10cm diameter
Standard: 14,5cm diameter
