Ok, we’re not sure this DIY quadcopter is so deadly as it could be. As you can see in the video, recoil of every shot throws this gun mounted drone back, so you unlikely can fire precisely at all. But it’s only the beginning!
Just think of it. Some guy assembled this drone in his garage. Its parts are cheap and the construction is easy. Then he just attached a pistol to it and get, as he wrote in description to the video:
Homemade multirotor with a semiautomatic handgun mounted on it.
Sounds easy and terrifying, huh? Now we have a flying gun and it can shoot. Upgrade the construction and add some kind of stabilizations which will lower the recoil and you’ll get a rather efficient killer drone.
At the very least it will be new dawn of contract hit.
