That is a strong cell around the drivers.

Interesting observation on the cyclic wiggle...It is conceivable that the cyclic motion is affecting the local flow in the downwash that affects the tail rotor, as otherwise, the torque demand would rise for steady rotor height. Am curious if there is a known reason why cyclic motion would improve TR effectiveness. It may be that the cyclic gives also a slight overspeed condition through the hysteresis of the governor, which would give increased TR authority.
