My fellow pilots and I were flying our quad/gopro rigs around for fun one evening when we were approached by an American business man who expressed enthusiasm for our machines and the HD results they yield (Zenmuse gimbal is awesome).
Before we knew it, we were contracted to conduct a film shoot in a remote location that was originally planned to be done by helicopter. So far the results have impressed the crap out of them and it looks like we will be getting offers for a lot more similar type shoots. We charge . . . . beer. Cheap really, but lots of fun. And using gear worth less than 1000 bucks.
