Imagine a large four-rotor drone with a seat and flight controls in the middle. A guy flies a prototype around inside a hangar-like building in the video. It's Russian, says the text. Interesting, but many potentially fatal problems come immediately to mind, given the lack of any sort of wing or autorotation feature.
