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.
