F15-0 Engines (29 mm)

The Estes F15-0 engine is a booster-stage motor specifically designed for multi-stage model rocket launches, making it an ideal choice for advanced rocketry education programs. With a 29 mm diameter and no delay, this engine provides consistent thrust for 3.45 seconds before handing off to an upper-stage motor. It’s built to support complex flight profiles and higher payload capabilities—perfect for lessons that explore propulsion, staging, and flight dynamics.

Designed with performance and reliability in mind, the F15-0 helps educators demonstrate key STEM concepts like thrust, mass, and momentum through real-world, hands-on experiences. Its extended thrust duration and high max lift weight make it suitable for heavier rockets, enabling deeper exploration of flight mechanics and multi-stage sequencing in the classroom or at launch events.

This engine is a strong addition to any school, camp, or STEM organization working with intermediate to advanced rocketry curriculum. It pairs well with upper-stage engines like the F15-6 or F15-8, allowing students to see the effects of staging and propulsion changes across different phases of flight. The F15-0’s reliable ignition and smooth handoff to the second stage make it an excellent teaching tool for multi-stage flight projects.

Each pack includes 2 F15-0 engines, 2 starters, and 4 starter plugs—giving educators the materials needed to run multiple demonstrations or student-led flights. The F15-0 is ideal for expanding rocketry education beyond single-stage launches and introducing students to the challenges and excitement of advanced flight design.
