This flight maneuver is for models of aircraft that were designed for inverted flight. Aerobatic aircraft and fighters usually qualify for this maneuver. After two (2) upright laps following the prior maneuver, the model may enter inverted flight. The model should make three (3) smooth, stable laps in an inverted position at Normal Flight Level height before recovering to upright flight at Normal Flight Level. Inverted height should remain constant for optimum points.
