You know the problem. So many vibration modes in the CC. I am still experimenting with mounting solutions. For sure you cannot screw any kind of camera to the aircraft structure directly. It has to be isolated as best as possible.
This video was shot with my "latest mistake" for a mount. The entire scene was shot at or below 60 mph. We are working with a few retired engineers here on the island to come up with some kind of stabilized, isolated mount to fit a wide variety of camera types. If you have any ideas please join in.
