This is a Human, using his muscle power only trying to hover above ground in order to win a prize.
He got off the ground the other day with a 35 second hover.
And will make another attempt today (Saterday 23 June)
Dont expect to see a conventional type of spars and plastic film construction.....This Helicopter is very very big.
With the poor guy sitting in the middle of four rotors which he is trying to rotate by pedalling.
I would suggest that it is rather more difficult to stay aloft
the higher the copter rises, since one loses the small benefit
of the air being held compressed between the hangar floor and the underside of the rotors.
Its certainly a great piece of lightweight engineering.
You can catch their attempt live today at:-http://www.agrc.umd.edu/gamera/index.html
Its difficullt to spot the guy pedalling, since I suspect
others are preventing the copter from any lateral movement?
