3. Approx 90 0 TURN Approx 270 0 TURN DOWNWIND 520m Turnaround: pilot’s choice 150m 300m 120 0 ZERO LINE - Any flying behind zero line scores zero points. Either TEN or ZERO for take-off sequence. Second attempt at take-off scores zero. Takeoff sequence not followed, zero (0) points. Model takes off outside of the landing zone, zero (0) points. Only two scores a 10 or a 0 may be awarded for the take-off sequence. Takeoff is complete when model has finished turnaround to enter the box.
