Estes model rocket engines are simply the best! We have been making rocket engines for over 50 years. Estes developed the first machine to mass produce solid propellant model rocket engines which gave rocketeers a consistent and reliable way to launch rockets. Because of our quality and reliability, Estes engines are considered by many to be the standard in the model rocket industry.

STATE SPECIFIC REGULATIONS:
Model rocketry is a legally permitted activity in every state in the U.S. However, four states have laws and regulations that specify certain age or permit requirements.

California
In California one must be at least 14 years of age to purchase model rocket engines through size “D” and must be 18 years of age to purchase larger model rocket engines. Children as young as 12 years of age may receive and use model rocket engines under adult supervision while participating in a bona fide educational program. Permission of the landowner or local fire marshal may be required before launching. Many areas have pre-approved launch sites and times. It is also important to remember that a small number of counties and municipalities in California have ordinances that are more restrictive than state laws and regulations. Due to the sheer volume we are unable to track local ordinances.
