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 face may 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 change from 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 JPO Knowledge Bank. Do we agree or not??

I dont agree on having to change AOA of throttle. What is really needed is to understand that Groundspeed will increase during base leg on the wind conditions above. The pilot will need to either do the downwind leg farther from the centerline, or need to carry the necessary throttle and speed for a tighter turn than expected. Otherwise, will miss the runway
But none of that has anything to do with AOA and throttle settings regarding airspeed. It is all about keeping the airplane inside the fixed box we want it to be, even if the air where it flies is moving...
