Model rocket. ­ means a rocket

Model rocket means a commercially made rocket that is propelled by a rocket motor; that contains a device for returning it to the ground in a condition to fly again; whose structural parts are made of paper, wood, or breakable plastic and contain no substantial metal parts; and whose primary use is for purposes of education, recreation, and sporting competition.

Model rocket means a rocket that is propelled by one or more model rocket motors and that has a total installed impulse of 160 N-s or less. (Note: changing the definition from 80 to 160 N-s affects the definition "model rocket"/"modèle réduit de fusée" in the Canadian Aviation Regulations, which states "means a rocket (a) equipped with model rocket engines that will not generate a total impulse exceeding 80 N-s (b) of a gross weight, including engines, not exceeding 500 g; and (c) equipped with a parachute or other device capable of retarding its descent." The Can. Aviation Regs have to be amended to follow new definition of model rocket -- less than 160 N-s, etc. [Client has agreed to speak to Transport Canada in this regard.)

Model rocket means a toy or educational device that weighs not more than 1500 grams, including the engine and any payload, that is propelled by a model rocket motor, and that conforms to the definition of “model rocket” in the 2013 edition of the “NFPA 1122: Code for Model Rocketry,” or a more recent edition as adopted by the State Fire Marshal.
