<div class="IPBDescription">Using my 3D printer</div>So I built a quadcopter with <a href="http://www.thingiverse.com/thing:26041" target="_blank">parts</a> that I designed and printed:

I'd always intended to rig it up with FPV gear, so I could view an onboard camera through a pair of video goggles whilst flying it. I've had a spate of bad luck with the electronics, but a friend lent me his video transmitter and I hooked it up. The result was incredible:

Watch it in HD.
This is my second FPV flight ever, and it is awesomer than anything.

I do have to say, that I'm slightly upset that you didn't have it come down and look at you as you were flying it :P
I wish I had a 3d printer. :X
Was thinking about doing this with my 450-class heli, but getting a stable camera is a pain with the increased vibration inherent. Have enough trouble just getting rid of most of the jello-effect on even a keychain cam. That and I need to find a monocular so I can just close one eye for flight, and swap when coming in to touch down... a heli won't stand for that kind of rough landing. Out of curiosity, what was the blue ring that broke on the second/third landing? Just there for orientation purposes?
That's flying with the throttle at about 25%. I've strapped 600g of steel to the bottom and it still flies. I suspect it could lift about 1.5kg before starting to struggle.

The camera is a gopro on loan from a friend. The HD video is recorded in-camera, and an SD stream comes down to my goggles. My camera has a smaller field of view, and doesn't do recording. I'm not that interested in a headtracking setup since the quad can rotate on the spot anyhoo. If I were flying a fixed-wing I think it would be worthwhile. In terms of vibration: I think the gopro does some of that internally, but this frame vibrates very little. In that video it was just duct-taped to the underside.
The blue ring is one of the landing struts I designed and printed on my 3d printer. Each one is about 5 cents worth of plastic, when that one broke I clipped on a spare. It's designed to be thin and flex a bit on landing, but I came in with a fair amount of horizontal velocity, so it snapped sideways.

Sadly, with the current FAA ban on commercial unmanned aerial videography/photography still in place, the big houses have been restricted to non-US operation or taking video from an actual helicopter (at much greater cost), while hobbyists are getting stung for even doing small jobs (aerial shots for real estate listings, etc). Hobbyists are still fine, just something to be careful about if you'd meant to add it to any professional portfolio.
Scythe, very nice; must have your props balanced quite well. Most of the GoPro footage I've seen gets hit pretty hard with the rolling shutter effect, unless quite a bit of vibration isolation is used. :)
Ahh. From the initial shots at the top, looked like you were using straight leg struts.

The last one is the one featuring a long, straight line ending at a tree.

Home-made sells mendel reprap. There's an ooold thread <a href="http://www.unknownworlds.com/ns2/forums/index.php?showtopic=111259" target="_blank">here</a>, with some photos of old and newer prints.
