overpitched,

The place you have to work on in your logic is that you are still feet flat on the ground, looking at the aircraft in wind, and seeing this wind as some kind of force on the aircraft. This is fundamentally flawed. AS the wings and rotors see it, the air is just there, all around, and its relative motion is caused by the engine. The wind is useless as a force generator once the aircraft has lifted off the earth. Please try not to see the wind as pushing on the aircraft, it does not.

Ask this question: If I tried to fly a stringless kite, how might it fly? Unless the string is tied to the earth, the kite simply flutters down, as it has no airspeed.
