Scale Altitude rules
Scale Altitude Competition comprises ten events open to any model rocket that is a true scale model of an existing or historical guided missile, rocket vehicle, or space vehicle, that has flown under rocket power. The purpose of this competition is to produce an accurate, flying replica of a real rocket vehicle, that exhibits maximum craftsmanship in construction, finish, and flight performance; and to achieve the greatest possible altitude with the model.
The model rocket and its flight must comply with the rules of the Scale Competition (Rule 50) and shall be judged for scale qualities and awarded scale points according to the rules for Scale Competition.
The Judges may disqualify any model that, in their opinion, does not show sufficient scale substantiation or evidence of the normal level of workmanship required for a scale model under the provisions of the Scale Competition. The intent of this rule is to eliminate from competition any entry for which scale qualities have been grossly subordinated in favor of altitude performance characteristics.
Scale Altitude Competition shall be scored as follows: the total number of scale points awarded to the entry shall be added to the altitude in meters achieved by the entry. The contestant achieving the highest score shall be declared the winner.
Damage shall be judged cumulatively with each flight, assessed from the judged condition of the model to the condition presented to the judge post-flight. The only exception to this is damage caused in the course of a catastrophic failure under Rule 11.5, in which case such damage shall not be counted against the flight points.
This competition is divided into classes based on the maximum permissible total impulse of the motor(s). The following classes of Scale Altitude Competition are established:
