Power your next flight with Estes single-stage model rocket engines, proven safe, consistent, and reliable through more than 500 million launches. Designed to carry a rocket through its entire powered flight using one motor, single-stage engines are the standard choice for most beginner, sport, scale, and high-altitude model rockets.
Explore a wide range of engine classes and delay times for rockets of different sizes, weights, and performance goals. Choosing the recommended engine provides the thrust needed for a stable liftoff while timing the ejection charge to deploy the recovery system near the peak of the flight.
Thousands of Estes engines are static-tested at the factory to verify reliability and adherence to performance specifications. Estes model rocket engines meet applicable code requirements from the National Fire Protection Association and California State Fire Marshal, and are certified by the National Association of Rocketry.
