Human power Helicopter video, so freaking awesome

Well they just need a bigger hangar.

I think he never gets tired because they run out of rope for the rotors so he does not have a chance to reach that point..

yeah take it outside.... let the wind get under it....

Really? I haven't seen it.

Maybe it is.

It is still way cool. Thanks Ricardo.

It just feels like an elaborate internet troll, like liquid mountaineering.

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..

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.

I bet you are right, I was thinking the same thing..

[NomadRip]

Brilliant! I hope they get it.

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')

IIRC Neal Saiki did this first (human powered helicopter) in 1989. Just didn't do 10ft and that amount of time.

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..
