I stand by my assertion, which has little to do with handling.
Who will post the manifold pressure, wind speed/azimuth and headings for a steady hover in any helicopter, to prove the assertion that the rotor knows which direction the wind is from?
Who believes the drag of the fuselage moving sideways or backwards at 6 mph is enough to actually measure by any means they have at their disposal?
The problem is that these myths exist only as we are taught them, and they die hard against the cold light of data.
Except for rare occasions where the tail rotor wake upsets the main rotor flow, or where the main rotor wake vortex rolls up into the rotor tip, a single rotor helicopter in light to moderate wind has no difference in power required for a hover, regardless of the wind direction.
Furthermore, zero wind is the worst for power required, and any wind from any direction is better for performance. In other words, a helicopter hovering downwind is better performer than one hovering in zero wind.
