This is what happens when you attach a chainsaw to a drone

Back in July 2015, an American attached a handgun to a quadcopter drone, and the internet became a touch... worried. 

"What ridiculous device might someone fix to their robotic flying machine next?" we pondered. "What devilish death device will someone cook up in their back garden in 2016?"

The answer: a group of Finnish farmers have created the 'Killer Drone' - a DJI S1000 octocopter drone complete with chainsaw attachment. 

Useful for terrorising snowmen, balloons and mumsnet.com members - the Killer Drone actually comes into its own when you're trying prune trees or lop off branches in awkward positions. 

Either way, it's still pretty good nightmare fuel.
