I know it has been a while, but everything flies as planned. With the 3600Ma batter I get about 10 minutes of flight time and the thing is screaming fast. I'm still using the very conservative setup for endpoints for the Turnigy 9x setup, which will prevent you from doing any real acrobatics, but nonetheless it flies!
On another point I bought a small Hubsan MicroQuad, which flies JUST LIKE THE REAL THING! It is a great trainer tool for flying a quad that is set up on the KK2 board.
