The energy efficiency argument is tricky though...
Fully agree on all points. But as stated earlier, EDAT is a good baby step for electric distributed propulsion. Because if you can’t do an electric tail rotor requiring only 1×E-7, how will you ever do an all electric EVTOL requiring a probability of failure better than 1XE-9?
