Here are a few more pictures of the guy.http://afp.google.com/article/ALeqM5...7tMmr2zeQmiRig

From the photos its amazing simplicity - he's got a front-wheel car
driveshaft running the rotor and implementing rotor tilt. Hey if he
only gets it off the ground thats flying. Don't forget helicopter
ground effect, valid for height of one rotor length. Thats probably
where he could get the 7? feet. Less power needed to hover near ground.
