Gamera II is the second human powered helicopter from the University of Maryland’s Alfred Gessow Rotorcraft Center.The NAA has certified this flight by Kyle Gluesenkamp as a new record at 49.9 seconds!
This flight surpasses Colin Gore’s incredible 40-second flight in Gamera II of a couple days ago (http://youtu.be/S-k-3efasOk), and a new world record for human powered helicopters!
It has since been surpassed by Colin Gore in Gamera II XR who flew for an official 65.1 seconds in August 2012. http://www.fai.org/fai-record-file/?recordId=16616

This flight was almost five times longer than the current official record of 11.4 seconds, set by Judy Wexler in Gamera I last summer (http://youtu.be/n-qFhcL9mg4), and over twice as long as the 19.4 second flight of Akira Naito’s Yuri I in 1994 (http://youtu.be/aR2CV1OeUdU)
The team is pursuing the American Helicopter Society International’s (AHS) Igor I. Sikorsky Human Powered Helicopter Prize (http://vtol.org/awards-and-contests/human-powered-helicopter), which requires a 60-second flight and 3m (10 ft) altitude.

it woultn't fly to any hight above 1 meter…air pressure above ground is bigger….if it would fly even 50cm higher, pressure would decrease….so that's why it didn't continue in rising up:…..the same with high speed pc fans….it would rise few milimeters above ground but that's all…..ground effect
it is more efficient to walk
The people that troll these videos are the same people that say Curiosity is a waste of money.
Where is the Video of your Build then?
Now get Coleman to pedal that shit and you can cross the Mississippi
You obviously have no clue what kind of engineering went into that thing. It is, in fact, the most aerodynamically and energy-use-wise human powered helicopter ever in existence. If they wanted to power it from about a dozen laptop batteries, it could stay aloft for an hour.
"it doesn't really fly, it uses ground effect".
in short, it really does fly. lift is lift.
Birds use the ground effect too. Are those birds that do this unable to fly too?
wow that did not look safe for the guys in the middle
hey at least it gets off the ground and stays off it
you spend more than thousands of dollars just to lift that thing 5 inches from than ground…oh well,anyways that seems to be a good cardio work out …
bird: "LOL"
Is it using some kind of gyro control of the rotor pitch to control attitude, or are there people holding it stable?
Fake
UP UP AND GO
I'd love to see Sir Chris Hoy on this bad boy!
Sweet birkenstocks bro!
The difference here is that if you attach blades to the edges of your grandma's bed sheet it doesn't become a totally sweet (if impossible/implausible) zombie area-attack weapon.
intact fibulae define failure
Bullshit!
I bet you couldn't take-off from the ground under you own power and fly for any longer than one-tenth of a second (only jump) with a bed-sheet. And if you jumped off a building and glided with just a bed-sheet for longer than 50 seconds, you would be well-and-truly in the record books. You are what I call a "knocker". You go and build a human powered helicopter and beat the record (if you think you are better than them) dip-shit.
What do you expect, dip-shit?
Mannn Shut the hell up!
Prove to me that it's fake. Why do you think it's fake. Don't you think it's possible? Where did you get your fucking aeronautical engineering degree (from a young earth creationists website). How do you fucking know?
HA HA, you lost that argument didn't you! lol
So did the Wright Brothers.
You lost for being dumb enough to take that comment serious & make that dumbass reply
That's a cool project!!
it people like you who try different things who can really say they've lived
Good work
Ground effect is NOT a force which can be used like you suggest. Ground effect actually is the single thing hurting him. It is harder to fly because of ground effect.
why use a nerd to pedal? why not get an athlete?
hshs, cool stuff, looks interesting, but long flights won't be possible, good for obese people to exercise and loose some wright and get fit too.
You should hire Robert Förstemann for your helicopter.
