Real. Seen a lot of model ornithopters fly.

You must have seen Festo's other swimming/flying/floating creatures?

I thought it was a bit odd the way the man was able to pluck it out of
the air, ie it ran out of steam right over his head.

Also, it was the sort of thing you'd want to fly outdoors with plenty
of room for error.

Also the footage was not continuous.

Plenty of indoor/outdoor ones

I see no reason for it not to be real. They were trying these things in
the 19thC but lacked the materials and the knowledge of how the wings
worked in detail. That can be seen now with high-speed cameras and
there's plenty of experience understanding drag, lift, etc etc.

I'd be surprised if there's any future to it for actual planes. Nature's
had billyuns of years to perfect the materials that go into actual
birds' wings.

There is interest in making covert surveillance devices that look like
real birds.

It's obviously photoshopped - I mean, look at the cheap suits.

I had a clockwork flying bird as a kid... You wound up a small crank on
its tail, and off it flew.

Radio control and all that makes it far more snazzy, but hardly rocket
science.

There are certain advantages in terms of STOL and low speed flight..an
ornithopter is somewhere between a light plane and a helicopter.


And its quieter than a helicopter.

One assumes the man on the transmitter had practiced that.

Not really.

No, I remember them too. Of course it just flew (sort of) straight and level

They're normally sold by dodgy looking Moroccans.

I can't see any clockwork ones on eBay. Plenty of rubber-powered ones
though - is that what was meant?

been a few ornithopter toys powered by electric motors and IIRC rubber
bands in the past.

Yerrrs... but in what direction...

No real market,..

Anyway, lots of fun here....from a Jap with a flying DRAGON.

The principles are well known, but the engineering esp. in terms of
weight are a bit challenging.

I THINK there are some kits mentioned in that whole forum.

But I'd guess flying a 'thopter is not that easy.

yes! A friend had one a couple of years back I think. Total hoot.


You need a LOT of power So flights are seconds only.


here's some rubber band ones..got to be the Xmas present with a difference..

http://www.birdkit.com/models.starter.html

nice electric ones for indoor and sub micro radios..

http://www.indoor.flyer.co.uk/orni.htm

Or outdoors, this is rather nice.

Nothing particularly special really. Flexible sheet wings, and a front
rib that flaps up and down with an orbital action allowing the wing to
present a smaller surface on the upstroke. (not as elegant as the one in
the video - but functional)

Radio control and all that makes it far more snazzy, but hardly rocket

Its nice - granted; but I don't find it that earth shattering.

Actually ornithopters are rather kewl.

I must build one next year. Freak the dogs out anyway.

Rather fancy a pterodactyl
