U.S. Model Rocket Sporting Code
The U.S. Model Rocket Sporting Code is the rule book for NAR competition model rocketry. From time to time, the Sporting Code undergoes major revision and a major revision was approved. The USMRSC (July 2021) edition is the official rulebook governing all NAR model rocket competition.
Minor updates to the Sporting Code are made annually through the Rules Revision Process.
Be sure to check out the Competition Guide for more detailed information about competition. Each of the events has a separate section, with tips and plans for models.
The online version of the US Model Rocket Sporting Code is maintained by a volunteer from the NAR Contest Board. If you have comments or corrections to make to the contents, please do not contact the NAR webmaster — contact the maintainer instead.
