Forget the loops...go back to original simple question: does turning DW cause any effect re altitude?
Trim/power for straight and level flying into a significant wind. Hands off. Quickly initiate a 180 turn/let the model turn itself. Then make no control inputs, no compensations. What happens? After the 180 is complete and leveled, the model keeps losing altitude until it has fully caught up and exceeded that steady sea of air to return to the original AS. The amount of time that takes obviously proportional to the height loss....and, yeah, going pretty damn fast, now, relative to the Tx....and definitely lower in the sky.
Greater the WL/wind/the closer the AS is to the wind speed, the greater the effect. A powered feather be less noticeable; only a model w/ no mass would truly show no DW altitude loss.
Myth of the myth exploded. Period. But I know it won't be for some.
