We've mounted a GoPro on my friend's RC Helicopter and went for a test flight in Klüsserath. It was balanced well and everything went fine until we managed to almost flip it over and crash it into the ground.
It will take some time to repair it. In the Summer we want to try the Phantom 2D3D. Hopefully with more luck.
