    Model rocketry is a safe and widespread hobby. Individuals such as G. Harry Stine and Vernon Estes helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes [1] [13] [14] and by commercially producing safe, professionally designed and manufactured model rocket motors.

    A high-power rocket launch using an APCP motor. Commercial APCP rocket engines usually come in the form of reloadable motor systems (RMS) and fully assembled single-use rocket motors. For RMS, the APCP "grains" (cylinders of propellant) are loaded into the reusable motor casing along with a sequence of insulator disks and o-rings and a ...

    Estes model rockets are popular and used by a large number of hobbyists and educators. However, measurements reported by a group at the University of Central Arkansas found that Estes rocket motor models A3-4T, A8-3, B4-4, B6-4, C6-5, and D12-3 have a measured impulses from 15.4% to 22.8% below the claimed impulse.
