These models are replicas of full-scale aircraft.  They are judged for workmanship, accuracy of detail, and other factors.  They must fly and are scored on their ability to take off, land and perform other tasks.  Precision Scale aircraft are the most detailed models and must be accompanied with airplane documentation showing the model's fidelity to the full-scale aircraft.  Sport Scale requires less-precise detailing, and the aircraft are judged from a distance.  Profile Scale is similar to Sport Scale, with the added provision that the models have profile (slab) fuselages. In Sport and Profile Scale, flying increases in importance.

Allen Goff gave new meaning to the term Dawn Patrol when he was one of the first pilots up with his Neiuport 17 World War I fighter. The flying started at 7 a.m. in both circles.

The airplanes were unpacked with care and assembled with static propellers so that the judges could compare the models to the pictures of the full-scale aircraft that they were copied from. Points were added up to determine the static scores, but they won’t be revealed until the first flight is complete.
