- relative size of circles
- close meetings at top and bottom (less than one wingspan apart)
- simultaneous 180° turn at bottom
Call IN when the kites are flying towards centre window, at <50. Both kites start flying the circles at the same time; the bottom kite flies the large circle and the top kite flies the two smaller ones. The kites should meet at the top. When they arrive at the bottom meeting point again, the kites spin 180°. Call OUT after at least 50% horizontal flight.
