Dumbest idea ever! I am a magician and a drone operator...first flying a drone indoors without gps
to help keep it in place is not easy. Second, throwing cards into the props will cause it to crash
and potentially injuring someone. Even if your audience is a distance away, the drone may not just
fall straight down. I wonder if the creators of the trick has thought of what the FAA would think!
Yes, the FAA has deemed that drones are aircraft and must follow certain rules. One of which is not
to fly near crowds.
This is just a bad idea on so many levels!
