A very interesting video from the Vertical Flight Society.
So I was initially thinking about 2 rotors like this for Sentach except running port / starboard rather than fore and aft. The thing is that the application is different. I’d like to take Sentach out to 300ish knots for small payloads and get 1000km range. Smaller payloads require a smaller vehicle. Thus we can stay with the wing model and use VTOL not for hovering so much as just punching off the ground and not needing a runway.
