Nope, it's less stable as the giant rotor acts as a large gyroscope. Quad copters work well with ultra-light weight electric motors, but the concept is focused on quickly changing how fast the blades spin so it does not scale very well.
@lultimouomo having a real-time computer to control four rotors in not something unachievable with current technology :) I would say that it's becoming almost a DIY tech.
