    I think it's a different one.

    That was fantastic. Reminded me of the Gossamer.

    Oh man that was so long ago, really awesome accomplishment..

    Many years ago I when to visit Paul MacCready's shop but it was all "Militarize" so no way to just say hi..:huh

    Amazing. Da Vinci would be proud. I was wondering if the reason for not getting to 10 feet. Could it be ground effect. Once you get to a certain height you loose the help of the ground for the downward air movement or thrust? No engineer here but have flown rc gliders and when you get close to landing the plane it floats until the speed drops.

    very very cool. And a pretty awesome display of ultralight structures. It appeared that they could benefit from some cycling theory about cadence, and gearing. I think they're soooo close. I would imagine, though every ounce is precious, and working in a directional controller that works--while you are peddling your ass off--is going to be a hell of an ambition.

    Yeah the structure is awesome, will be great to see how they build it "Crazy glue" instead of epoxi...??
    yes 10% reduction in RPM will get them more stable and less bouncy, then again maybe they are approach it as a "Anaerobic" exercise, who knows I'm sure they have very smart people around.
    That is a the next big challenge, even with a "Hand to control it" is complicated, never mind the means to accomplish it, very interesting project none the less (I'm been following the helicopter challenge since I was in Design school in the 80')

    Thanks for the link, I still remember the video of the small propellers trying to spin the "big wing", awesome start for a really crazy challenge..:ricky

    true, and I was kidding. I hope them all the best. I do wonder why they don't have strategically placed ropes to "handle it" when it starts to go bad so it doesn't crash. At least for the tests.

    My first impulse was that they would incorporate a swashplate...but with their design, they'd have to coordinate four swashplates....that's ridiculous.

    I think a torque differential is the right approach. HID requirements have to be pretty darn intuitive, and will most likely minimally involve the hands...certainly not fingers.

    Man I can not stop watching this video (and the other ones too) to me this epitomize all the things I love about the design (and Engineering that I'm not legally) and my dreams when I enter my master in Biomechanics of focusing in Human Power Machines and I just want to whole world to see it.

    Any more links, videos and articles are very much appreciated..

    I think the highest my middle school students hit was .4 horsepower, as measured by my bike-dyno. And that was giving it everything they had, measuring just the peak. No way could they hold that for any amount of time.

    Very cool copter. Wonder if the lack of control is due to the added weight?

    If you ever look at a helicopter, take a gander at the rotor. There's enough levers/nuts/bolts there to choke an elephant. Control on a helicopter is achieved by "warping" the rotors, causing it to tilt in the desired direction. Takes a lot of parts to be able to do that.

    Edit: for example...

    Oh you don't need to tell me, many years ago I got to work on a bunch of Bell UH-1 Iroquois's (Huey) and I got somehow familiar with their inner workings..

    I do think they broke down the task, and decided to address the biggest question w/o any complications. The legacy of the prize is testament that it's a big enough ambition to just prove 1 aspect of the entire question; can a human levitate 10' off the ground by his/her own power if that were his/her sole ambition? If we can't prove that, the other details are irrelevant.
