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).

New brushless motors

As some of you might know, I am using Scorpion S-2212-26 motors for quite a while now. I am extremely happy with these motors.
Short time ago, SCORPION POWER SYSTEM LTD offered to provide three recently developed motors (prototypes of the SII-2212-960KV) for tests with my tricopter . Of course I didn't say no...!! I had the opportunity to test them recently, and these motors are absolutely great! They seem to be even more efficient and powerful than the S-2212-26 I used before. These motors stay absolutely cold (prop: EPP 10x4.5'') even if I do aerobatics with my copter. I am not a real expert with motors, but if no heat is produced, all the available energy should be converted to mechanical energy/ thrust... And that is also what it feels like :-D . So, I would absolutely recommend to use these motors with my tricopter!
And last but not least, they look pretty nice...


  1. SII-2212-960KV seems to be not listed in their web site. Do you know from where can we get it?

  2. Hi! These motors are prototypes and I don't have information when they will be available. You could ask them, I am sure they'll give you a quick answer.
