On RC Groups. Check out the video, it's really smooth!
Mikro sez: "The whole system is quite impressive. I always thought one needed to have the custom modified I2C ESC's and expensive motors to be able to lift these loads with the stability you'd want for aerial photography. This design proves you don't and it has a lower price point than the other approaches. Thank you VERY much Mike Dammar and Mike Cook (Old Man Mike)!"
