IN is called when both kites are flying towards centre window, at about ^40, before they reach 50. After a horizontal leg of about 30% both kites turn 90°, both downwards. When they reach ^15, both kites turn into a semi- circle, diameter about 15%. Both kites then fly upwards until about ^85 and again turn into a 15% diameter semi- circle. Flying downwards both kites perform a 90° turn at ^60. OUT is called after 30% horizontal flight.
