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).

Tilted body race quad update 2

All carbon parts are milled, the 3D printed parts are ordered, and motors + ESCs arrived. I can start to assemble soon :-D.

One thing that is new (except for the aerodynamic concept) are the airbrakes. I don't know yet how good they'll work and if they might introduce too much moments around some axis. But I think that they might be advantageous in racing tracks with a lot of tight turns. They'll be extended if the throttle is quickly reduced (hence reacting to the derivative of throttle).

Here are some renderings of the latest iteration:


DERBE airbrakes


  1. very eager to see this little beast in the air

  2. Yup.
    What Motors 'n ESCs are you going to use?

    1. Hey, I'll use Cobra 2204 2300kv with KISS 18A ESCs. Not sure about the battery yet, maybe 1300mAh 4S, maybe 1800 mAh...

    2. Well, I just watched the live stream of imonfire666 on a german FPV racing competition. He was flying at supersonic speeds and therefore I decided to order the motors he uses...: Graupner ULTRA 2806 2300KV. I'll test both 5" and 5.5" Graupner C-props.

  3. copy. Thanks.
    An expensive option, though. Hope the winner's award compensates that ;)

  4. great design, loving the airbrakes, could they possible be reversed to open towards the rear and used dynamically for yawing harder/faster?
