Next weekend, if everything goes well, a 15x30cm carbon deck will fly onboard HAPS-1 -http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1

One end of the deck will be the flight radio, the other is my responsibility, a single camera (Powershot A560 ), stand alone GPS logger (to 18km), and a small wide angle mirror so the camera can see the payload, the chute and the envelope above.

Still working on a hacked firmware for the A560 - but the intention is every minute will include 15s of video, and then 5-10 stills in fairly quick succession - with the hope that the rotation of the balloon will give us some mosaics out of each section.

More details, some photos etc, later in the week.

What wind speed hit still the payload box in the flight with the balloon? It isn't nearly zero, is it?

If you get still enough wind on the box, I would start/search some tests on the compact form of the box in order to get the rotation under better control. Maybe it could be even possible to control a desired speed and direction of the rotation during some time of the flight.
How about a compact rugby-ball-like form, maybe such deformed that you get a desired rotation? In this context it would be also relevant how the payload box is connected to the balloon/parachute cord - fixed or turnable.
