What I don't understand is when things like this are scaled up, would you not want the greater efficiency of a larger single rotor like a helicopter?
Even with the large drone manufacturer, why the cost of drone is so high? We have reached a point where we can build high performance single board computer under 100 dollars because we can automate the build process.
This technology has clear military applications. It is amazing watching the nature of war changing literally year by year.<p>I assume this is what it was like in the World War I & II era watching tanks being developed.
