My first reaction was the same. I have a small indoor quadcopter with 2 main modes: freestyle (like a helicopter), and an easier mode that keeps the drone hovering. My first thought was, why not use the easier mode (press forward to go forward, back to go back, etc.)? But looking at those war videos, these drones always come at an angle towards the target. And in that sense, it's easier to use the more difficult helicopter mode. What I mean is, once you know the helicopter mode, it's easier to do this kind of maneuver than using the "easy mode".
