If it's small duct tape will do as a mounting :-) I've used a similar
camera (it's about the size of a large thing of lipstick, hence is
called a 'lipstick camera') on planes and racing motorcycles.

Some examples (although the quality will be somewhat degraded by
youtube):

I also now have a completely self contained camera which cost (in US
money) about $70. Records to an SD card. It's not as good quality as the
lipstick camera, but it weighs only 35 grams and fits on a radio
controlled helicopter.

Could you post a link? One of those would
probably fit inside the wing tiedown eyebolt
on my plane.
