If you want to mount it in the kite, I would stay away from those super wideangle cams
Get a really good camera instead, that is way better, and can also be used for "general" photos in every single way
Sony TX20 or 30 f.ex, and you got it.
Or any similar camera, like a Pentax WG1 or 2 if you want timelapse also.
Lots of options and not as expensive and better suited as optical zoom, which is often needed when in the kite, and quality excellent..
Using these pov cams like the Go Pro or similar, does not work in a kite IMO
You see the whole world as a small ball, because it has no zoom at all, only the fisheye angle which is no good IMO.
For a linemount they are fine (but really wiggly and not that good)
But for a kitemount, you can get way better cameras and cheaper - besides the fact that they can be used much more and for other things too
