During the descent of the kite as it was rotating, its two lines rotated “each other” (the video shows it), the length of the two lines being fixed. A series of rotations in the other direction would end up separating the 2 lines. But perhaps your device would allow continuous looping without excess of “rotating each other”?
I’d noticed that when the kite descended while turning, it seemed to be able to stabilize above the ground (ground effect?).
