Aircraft Specifications

This Free Flight model may be from a kit, published plans, or of your own design; be creative!
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, carbon fiber, tissue paper, and/or plastic film.
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.
A wound rubber band shall be the sole source of energy to turn the propeller (No R/C, electric motors, engines, catapults).
Flights will be timed from the moment the model is launched to the time it lands, measured in seconds.
Scoring and bonuses

An example of a model with a stick fuselage, and balsa and tissue wings.

a) Final score will be flight time multiplied by 125% for all balsa wood,
