Eli5: what are the benefits of a normal helicopter design vs a quadcopter we see on drones?
In: 210
I feel like something everyone is missing here is that the OPs question seems like a question of design, rather than a question of current practical implementation. One user commented about autorotation being missing from current drones, but didn’t consider adding it to hypothetical quadcopters and seeing if they are still as safe or unsafe.
So the question could be, and is possibly still unanswered: assuming each style (quadcopter and single-with-tail) has all of the general technology benefits of the other style (having rotors on a quadcopter, for example), what are the inherent benefits of the heli styles single-with-tail versus the quadcopter style, for the same payload capacity?
My first thought, is that two motors is less expensive than four motors. The takeoff/landing ground area is smaller. What else?
