On August 12, electrical/aerospace engineer and helicopter pilot Pascal Chretien took to the air in the world's first untethered, fully electric manned helicopter flight in a prototype machine that he designed and built almost entirely by himself within a 12 month development period. In his 2 minute, 10 second test flight, Chretien beat aviation giant Sikorsky into the record books...

...Chretien was able to achieve an 87.5% energy efficiency between the battery terminals and the rotor shafts...

I've always been struck with the simplicity of
mechanisms in model helicopter craft. He seems
to have borrowed from some of these ideas.
I like the auto-gyro like control set. Also, any
computer flight control algorithms *start out*
more basically for helicopter then a trajectory
controlled one for a winged aircraft.
