Harry C,
Your 2nd modified paragraph is correct with respect to the model gaining ground speed while flying downwind and loosing ground speed while flying into the wind. A crosswind situation with the wind directly in the pilot's facemay require additional throttle or a reduction in AOA while turning to final on the crosswind leg. This is all from the perspective of the obsever/pilot.
The model airspeed remains equal with a constant throttle and AOA setting independent of the wind speed and direction.The speed appears to changefrom the pilot's position. The original text was written by a experienced full scale and model jet pilot. Some wording/meaning may have gotten twisted during multiple edits for inclusion to the JPOKnowledge Bank. Do we agree or not??
