The model aircraft approaches in straight and level flight on a line parallel with the Judges’ line. After passing the judges’ position a smooth climbing turn is commenced away from the judges. At the apex of the turn the bank should be at least 60º. The nose of the model aircraft then lowers and the bank comes off at the same rate as it went on. The turn is continued through 180º to recover straight and level flight at the same height and on a heading opposite to that of the entry. A low powered aircraft would be expected to execute a shallow dive at full throttle in order to pick up speed before commencing the maneuver. This option may only be nominated for non-aerobatic aircraft.
