You can tell he isn't flying it, he's using a tablet which would make for a very poor remote, you'd do better with an Xbox 360 controller. You can see it flying around a bit when he isn't even looking at it too.
Aside from it looking fake, another nail in the coffin in safety. There is no way he would be allowed out in the open like that with an armed quadcopter. Ranges have firing lines for a reason, so no one walks into danger and gets killed, with a flying vehicles the firing line is 360 degrees around, he would need to be in a bunker in case something went wrong.
