Evaluation of the quality of an aerobatic F2B flight is not easy. There is no objective measuring of the flight and maneuvers. Competition judges give their subjective grade for each maneuver. Also, during the 7 minutes flight, the pilot may be nervous or stressed. If he does not manage this, the quality of the flight may be affected. Still, this type of model airplane sport is both interesting and challenging.
