Keep a popular hobby safe by complying with the latest requirements for model rocketry as presented in new NFPA 1122.

Essential to public safety, the 2017 edition of NFPA 1122: Code for Model Rocketry applies to the design, construction, limitation of propellant mass and power, and reliability of model rocket motors and model rocket motor reloading kits and their components, for use by the public for purposes of education, recreation, and sporting competition.

A significant change in the 2017 edition allows rocketry users to calculate minimum launch site dimensions based on readily available software.

This edition allows another option for calculating the minimum launch site dimensions for original rocket designs or rocket kits, which cannot normally be obtained by manufacturers.  This change permits a consumer to accurately calculate the altitude that any rocket will attain with any motor and allows the consumer to obtain an estimate of the flight altitude that is subsequently used for determining minimum launch site dimensions.

The 2017 edition also contains an update in Annex B to the National Association of Rocketry's Model Rocket Safety Code to the current 2012 edition.
