This is the kind of shit that is going to have the federal government clamp down on it in no time flat.
Not untill someone see's this then gets the dumbass idea to put a .22 or larger caliber weapon on it at which point it becomes a weaponized UAV and there is only one purpose for something like that and the government will step in. I would immagine you could still put a paintball gun or air rifle on something like this and not break any laws ( I think ).
This video is awesome! Love the music in it.
ps. I swear i've seen video out there of an RC helicopter that had a pistol of some sort mounted to it. It was pretty sweet.
