- two sharp corners on the horizontal line at ^10
- symmetry of figure around vertical axis at <0
IN is called when the kite flies at ^10 before <80 is reached. Make a sharp turn at ^10 <35 upwards. Fly a straight line through point ^50 <>0 followed by a 270° arc (diameter of arc approximately 25%). After flying a straight line down, passing point ^50 <>0, again make a sharp turn into a horizontal line at ^10. OUT is called when the kite reaches ^10 >80.
