The third prototype is now completely assembled and ready to flight. The folding is a bit tricky, exactly as I expected. There are too many cables and the ESCs are just too big to place them at the center (if it should still be foldable). I was quite happy when I tested the camera and didn't saw the props on the movie. I also had to replace one damping ball with a stronger one, the black one was too soft. The complete quadrocopter weights 1'261g (including the battery).
I hope the weather tomorrow is good enough to make first test flights.
