AE24 Model Specifications for the 2022 Contest

  2. Wingspan shall not exceed 24 inches (61cm) when it is in assembled condition. The wing is the largest flying surface on the model no matter the configuration. Fuselage length is not limited. The flying surfaces shall provide the sole source of lift (no balloons etc.), and may be made from foam, balsa, and/or tissue paper.
  3. The propeller shall be an unmodified commercially available plastic freewheeling propeller up to 8.5 inches (22cm) in diameter. Weight may be added to balance the propeller. The propeller will be the sole source of thrust for the model.
  4. A wound rubber motor shall be the sole means of energy to turn the propeller (No R/C, electric motors, engines, catapults)
  5. Flights will be timed from the moment the model is launched to the time it lands, measured in seconds.

NEW for 2022: Bonuses for balsa and tissue construction.
A. Final score will be flight time multiplied by 125% for all balsa wood or balsa wood & tissue airplanes with a stick fuselage. No foam flying surfaces.

B. Final score will be flight time multiplied by 150% for all balsa wood or balsa wood & tissue airplanes with a built-up fuselage, where the rubber motor is inside the fuselage. No foam flying surfaces.
