Please understand that once the airplane is airborn it the only "wind" the plane encounters is that caused by the thrust of the engine pulling it through the air.
Neat! Where does the sidewind go in your magic neutral world? The stuff that makes your loop drift downwind so you enter at an upwind spot relative to your point of reference as to where you finish. The stuff that makes (or allows) you to crab in with your nose pointing in a direction different from your direction of travel. The stuff that raises one wing in a situation where the landing strip doesn't correspond to the wind direction. The stuff that lifts a flat-bottomed or semi-symmetrical winged model suddenly . . . or drops it just as quick when it stops.
The model may not sense it; but I'm on the ground with the rest of the hard 'ol earth and I sure notice the model being effected relative to my position when there is wind.
