A few segments of my recent build flying in the rarefied urban area.
Featuring the best of that quad's stability and flight performance, along with some amateur camera work.
It may not look like it, but it's -12C outside.

I'm excited!
Finally, a stable flying platform with a decent camera!
Unfortunately, excitement kind of cancels out caution - a few minutes later the thing would run out of batteries while still in the air and go FUBAR.
The crash itself was not filmed due to lack of external cameras and lack of survival of the last minutes of on-board camera's recording.

wow, nice pictures, good quality!
What camera did you use?

What camera did you use?Samsung ES10.
Essentially, a random soapbox camera i had lying around that i didn't mind smashing.

Turned out to be pretty rugged, but being landed on tend to knock the batteries out, removing the last 30 seconds of video.

Looks very nice that you got it flying!

I wonder, are the two first pictures taken in picture mode, by some continuous triggering, and the last pic extracted from video? I've never ever been able to get a good still picture from a quad!

Does that Samsung have a panoramic shooting mode? A couple of those pictures have a pretty wide field or was there some picture stitching involved?

Well, video is essentially a series of low-res stills took rapidly.
To get something better than that, picture stitching is involved.

For example, in the second segment of the first video there is a place where the camera looks at the building and does a left-right gesture (2:25).
Stitch&crop:

Most of the spinning around action was specifically intended to get material for later stitching into a wide-field stills:

It's important that the quad stays more or less in the same spot for all shots, or there will be borderline artefacts.
Obviously, that's the hardest thing to do :)
