I've been experimenting with aerial photography and videos lately.
After breaking my more complex mount that needed half a roll of duct-tape to keep it in place on the keel, I've made up a more simple mount from old Battens, wall plugs, threaded rod, some nuts and a vario mount.
I discovered that the ball joint on my vario mount threads into the arm that connects to the vario with the same thread that is standard to screw cameras on to tripods ( 1/4-20 ? )
So, the very very simple version is to just screw the camera straight on to the ball joint of your vario mount.
