My research is Automatic Flight Control System Design of Quadrotors (Drones). We use commercial Platforms such as "Asctec Hummingbird", "Asctec Pelican" and custom made Quadrotors and Hexarotors. In Collaboration with National Uni of Singapore we designed our own Autopilot. Maximum endurance (flight time) with 8500mAh Battery 20 minutes and assuming the flight is not resisted by any wind gusts. 30 KM range choopoo hor choopoo if you know what I mean !
