you have the most amazing landing-strip that I can imagine! That must be great having a plane in your backyard and the airstrip directly behind. I have already watched a load of your videos, incredible!!
camera stabilization is reasonably easy, put the cameras on a helmet :-)
I just need to keep my head upright, and remember to press the (waterproof) micro-switch, visible at the front, with my tongue every time I want a photo. That was the setup I had for night jumps, for the balloon-jump I did not have the two external flashes mounted on the helmet which makes it a lot lighter and easier to keep upright.
