Hi Pierre,
Without any active controls on the blades… Not yet. The rotor still needs a little lift. Hardly any though. Very scientific measure that.
It seems likely possible with actively controlled wings/blades.
The the blades were set banked a little (outer tip down) to aid expansion.
Interesting to consider if fairing on rotary torque lines could be set to expand the lines away from the axis. Not too far out from the axis like a skipping rope…
