Everyone here probably already knows the answer to that question. So the issue is not "miss handling" a downwind turn. The issue is that, as RC pilots, we are more concerned with position relative to a landmark (ourselves) than we are making a perfect 360 degree circle in a moving air mass. Yes, I can probably make perfect turns on a windy day without losing any airspeed or altitude, but my ground track will be no where near the flight pattern for my flying field. Therefore, I adjust my inputs to achieve the same ground track, which is needed to keep the plane in the proper place relative to the landmark (Me).
Yes, If I do this incorrectly, I will lose altitude and possibly crash, even if I do it correctly I may still lose some airspeed or altitude, but if I tried to fly the plane like a full scale would and make a standard turn and not loose any airspeed or altitude, my plane would probably be out of range of my radio or my eyes very quickly.
There is no "MYTH", there is just pure science and fact that is being confused by people trying to compare apples to oranges.
