The National Association of Rocketry was founded over 45 years ago. NAR has taken the lead in getting rocketry legalized in places where it was covered by obsolete fireworks laws, and is in the forefront of the effort to keep the sport from being regulated to death. NAR writes the competition rules and sponsors most of the rocketry competitions in the USA. NAR members receive individual liability insurance coverage. Best of all, you get a subscription to  Sport Rocketry Magazine. We at Pratt Hobbies are proud to be long-term members of NAR (like, since 1964). Write to the National Association of Rocketry, Box 407, Marion, IA 52302 or call 800-262-4872 for membership information.

The Tripoli Rocketry Association is devoted to the high power end of the sport. Through the Tripoli certification program, members can qualify to buy and use H and higher motors, hybrid motors and other advanced technology. Tripoli works closely with the NAR on regulatory and legal issues, and the two organizations are in harmony on their certification and engine testing programs. Tripoli members receive the excellent High Power Rocketry Magazine as a membership benefit. Write to Tripoli Rocketry Association, PO Box 970010, Orem, UT 84057-0010 for membership information.

We proudly support the educational programs of the Federation of Galaxy Explorers.
