Doesn’t the vertical surface become an issue in azimuth manoeuvres? I remember seeing data from a Brand X a/c that showed that the pedals were close to fsd a much lower speed when the a/c was travelling at 300 to 330 deg azimuth in comparison to the other azimuths. I concluded (possibly erroneously) that the relative direction of the airflow over the vertical surface was causing a horizontal “lift” force requiring the tail rotor thrust to be reduced to maintain the a/c heading. Again the beer induced assumption was that any increase in speed would have resulted in the a/c turning towards the direction of flight.
