When the GoPro Hero 2 cameras arrived, this little plastic mounting plate was glued to the top of the each box, presumably for display purposes?

In any case, the plate makes a really solid camera mount, albeit a shaky one.  In an effort to dampen some of the vibration and steady the camera, I cut up a piece of an old Gateway mousepad and attached it between the body of the quadcopter and the re-mounted the plate.

Here’s the finished product, with the GoPro waterproof housing attached.  Future flight videos and still images will hopefully be a little more stable now.
