Product features and specifications

The Estes F15-8 engine is a high-thrust, single-stage engine designed to deliver long-burning power for mid-size and heavy rocket flights. With an 8-second delay, it's a strong choice for rockets that climb high and need time for stable coasting before deploying recovery systems.

Built for performance, the F15-8 features a 29 mm diameter and delivers over three seconds of thrust for an extended, dramatic boost phase. Whether you're looking to push your rocket higher or experiment with heavier builds, this engine brings the power to make it happen.
