Three million plus views so far but I'm inclined to say that this is fake.
I don't see the thing working from a physics point of view. I have seen vids of quad rotors before and they are tiny...lightweight. I don't see this thing being able to lift itself. You have the weight of the aircraft, the battery, the gun, camera, ammunition and...if you totally buy what this guy is saying...enough onboard explosive to destroy itself with a fifteen foot blast radius. Plus it is enough explosive to destroy the car at the end of the video. Personally, I wouldn't want to be anywhere near something that can explode like that and this guy is handling it and standing right next to it as if it's nothing.
What about recoil? This thing shoots away and there seems to be little to no recoil or muzzle rise. What? is it supposed to be recoilless, too?
There is a lack of shadow being cast on the table at the beginning of the video...the car in the background is casting a very distinctive shadow but the quad doesn't, the stand doesn't and the "Russian" doesn't. Makes me think they aren't in the same place.
And he casually destroys the "prototype" at the end of the video as if it's nothing. Sure.
I am guessing that this vid is totally constructed out of whole cloth just like that fake flying suit video that was making the rounds a few weeks ago.
Oh, and I don't think this guy is Russian, either.
What do you think?
