Fly half-scale model empty, 1st quarter.
Build full-scale mock-up, 1st quarter.
Fly full-scale model & dummy, 2nd quarter.
Fly full-scale model & ballast, 3rd quarter.
Fly full-scale model & test-pilot, 4th quarter.
For we've only the materials currently to fly an empty phone-box. We could do so with a mannekin by additional motors, rotors and ESCs though the money ~ yours or mine ~ is better spent elsewhere... nobody doubts in 2023 that a large quad of this kind flying without a passenger could not do so with.
What will be more inspiring is seeing the same thing rendered at full-scale in the form of a mock-up ~ it's the same reason for instance that auto-makers build concept-cars that appear at places like the Geneva motor-show in order to get the juices flowing. There is no reason therefore why this should not be conducted in parallel with flying at sub-scale.
(Don't know why Blogger adjusted the line-spacing ~ doubtless due the import of that schedule ~ but then perfect is ever the enemy of the good).
At the same time there's no rush to fit eight motors when four will do, as any number of projects out there ~ like the jet-powered efforts of Yves Rossy, Franky Zapata and Richard Browning ~ are vulnerable to engine failure (and all three suffered dunkings as a consequence).
But does that put us off?
