I ran the numbers myself a while back, it’s not pretty at all.

Until you hear about people traveling >200mi and getting their commercial pilots licenses entirely on conventional takeoff fixed wing electric aircraft (see pipistrel electro) it’s safe to assume this vtol industry is grounded. The conventional fixed wing aircraft are wildly more efficient in terms of battery mass fraction and range but they don’t get investors excited like a personal quadcopter for the (ultra wealthy) masses.
