really good deal on this! i use this on film and at f.95 it's pretty much ridiculous on a rangefinder. always stop it down a bit. wildly fast and insane subject isolation!
Aerials are never cheap (we had fun getting a ship to the middle of the Canning Stock Route). However, you may want to consider grabbing a few with this

Thanks for the video, haven't seen that one before. We have a few shots we will be using RC helicopters but a fewer of the higher altitude shots require a full size helicopter. My father runs a helicopter company, but they can't hold the heavy gyro stabilization balls on the nose.
Have you thought about the Kenyon Labs gyros? I have never used them for video; but I have the 4x4 and 8x8 I use for still aerials with a Pentax 645D and 35mm to 300mm lenses. My shots wouldn't have been possible without them. I even use them handheld on the ground. 40mp is demanding and sometimes a tripod gets in the way when you are working on foot around elephants...
I would bet two or three of the KS-12's would suit you perfectly, the rent them too.
It will work for certain shots, and we will be using them for some boat-lapses to keep it as still as possible. But for the looking down and forward and ones that are zoomed in a lot the nose mount systems are the best. We will be using the GSS C520 for those type of shots. Otherwise the RC hell will do great, especially for work in tight canyons where it would be dangerous for a full size rig.
