I'm sorry...i know it's my inner 12-year-old acting up, but when I first heard (and each time I hear it subsequently) the word "Defikopter", I think about a drone that doesn't kill people, but drops a steaming pile of dook from altitude. The reality is that it's a defibrilator drone with a range of 6 miles that can potentially save the lives of people having a cardiac event (but it might deliever the defib machine in a brown cylindrical tube which would justify the name). Not that anyone I'd want to remotely drop a deuce on (I'm looking at you, Bieber) wouldn't be just as well served by getting a massive (and unexpected) jolt of electricity.
On second thought, Defikopter works either way. I'm thinking the electric shock might cause the loss of control with regard to bodily function anyway.
