I've essentially done this. I was in a location where flying the drone was 100% going to get me in trouble. So, I fired up the app, started the camera, and carried the drone above my head as I ran down the street. The gimbal was active and in the end, looked like a drone shot. Did the same thing shooting from the backseat of a convertible. People still ask how I got the footage.
Do you by have a link to the footage anywhere? I'd love to see how it turned out.
Unfortunately, I don't. It was all for a corporate gig, so the footage was theirs in the end. The link I had to the video is no longer active. They used it, and the got rid of it I guess.
Haha it definitely looks a little silly, but it's almost definitely a hand-launched UAS (maybe an Aerovironment Puma[1], as the caption suggests).
