Truly, we live in a golden age of Putting Dangerous Things On Drones. We've seen people strap fireworks, paintball guns, real guns, and even flamethrowers to quadcopters and the like, and so it was only a matter of time before someone tried with power tools. A group of Finnish filmmakers have stepped up to the plate, hanging a petrol-powered chainsaw underneath a DJI S1000 octocopter drone. The resulting craft — nicknamed Killer Drone, of course — looks like something from a sci-fi horror film, charging around snowy fields and bursting open the heads of unaware snowmen.
