Well the guys at RCToys have updated the specs on the Draganflyer - it's now the Draganflyer IV. The flight time is up to 15-20 minutes which they achieved by using lithium-polymer batteries and some optimized rotors.
There was some research done with version III to demonstrate automated flight patterns.
Also a mention of a robotics guy who built a handmade prototype for a Draganflyer (November 2002 - Dallas Personal Robotics Group)
