EDIT:The ESCs arrived (thanks to Eric!) and first flights were very successfully completed. The control loop had to be modified to account for higher demands of this micro tricopter during aerobatics and fast flights. Because larger Shrediquettes will also benefit from this modification, I will soon release a new firmware and a modified GUI. I will now start to collect some video footage and make a new movie.
This micro air vehicle is a hobby project. Three MEMS gyroscopes and a two axis MEMS accelerometer are used as sensors.
It performs very well in aerobatics ("acro mode"), but it can also hover on its own ("hover mode").
Watch this video to see what this project is about and to see the copter in action.

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...

Shrediquette DLXm
Here are some pictures of my Shrediquette DLXm. Unfortunately I am still waiting for the ESCs... Slightly annoying.

Your designs are great!
