My friend Graziano brought a new toy with him to our flying club on Saturday and we had some fun playing around with it. You can see for yourself in this clip, but basically it is a quad-propeller drone with a GPS and Hero3 camera on board. Grazi's accomplice on the ground used VR goggles to track the camera and follow his hang glider in flight -- the best sequence is actually one in which the drone almost collides with the glider -- you can't miss it because I counted it at least nine times in the video.
For me, this unit seems like the ideal platform for establishing shots since you can place it anywhere you want in the sky (up to 1500 feet) and it will stay right there until the battery runs out.
I shot some footage of us playing with the unit itself Saturday evening which I will post here as well (gives you an up-close view of the setup)
