Lilium Runs Out of Money

[Ed Haywood]

I have a hard time believing something with several rotors will be cheaper than 1 big one

The increased number of rotors is offset by much less complex power train. Each fixed pitch rotor is directly attached to a motor, with no gearing, cyclic, or collective.

That’s because eVTOLs were designed for densely populated urban areas and UAM. When you get outside of those areas it falls more under the RAM side of the overall AAM market. And it’s the RAM side that has been using the hydrogen based fuel cell technology and flying several prototypes but does not have the same investment base or support. However, I think you’ll see turbine-electric power sources used in conjunction with battery packs at the eVTOL level before H-fuel cells due to scalability issues.
