Rocketry Planet

The following motors have been certified by NAR Standards & Testing as of June 30, 1996 for general use as high power rocket motors. They will not be certified for NAR contest use as they are not model rocket motors.

The following are Kosdon reloadable motors, also known as "Kosdon Truly Recyclable" motors. They are certified only with the indicated size casing and manufacturer supplied nozzle, end closures, delays, and propellant slugs:
