I built two multi rotor (quads) around the same frame and designed the arms so that they could be used on both frames (less kit to carry around). This one used a PixHawk controller, full details are in the video.
No mishaps on the maiden flight, the aircraft was extremely stable. Mission planner and return to launch work well. All in all a good flight.
