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).

FPV videos, firmware tweak, user builds

Some days ago, I added two FPV videos to the video-section:

There are also some more details on the FPV setup that I use in the FPV section. Additionally, there is a new section showing some Shrediquette user builds. Please keep on sending me details about your own build.
Soon (next days) I will release a firmware update, that seems to reduce servo jitter, especially when using fast digital servos. Lutz Meyer tweaked some lines of the source code (thanks! :-D ). Lastly, for all people from northern germany, I would like to point your attention to a quadrocopter meeting that will take place on Aug. 21. in Bremen.


  1. fantastic !!!
    i never seen anyone make flips in fpv flight.

  2. Willian, you make the loops in acro or in acc mode ?

  3. Hi,
    I do them in acro mode, in hover mode it is not possible

  4. I would like to built a helicopter that can operate remotely using the PC with the mouse or keyboard, or the radio control connected to the PC.
    I also attached a small video camera to the helicopter, which gives me the images on the monitor where I'm going. Do you have an idea how to built it and if it is possible to assemble?
