F15-8 Engines (29 mm)

The Estes F15-8 engine is an excellent choice for educators and student teams conducting advanced model rocketry activities. With 49.61 N-sec of total impulse and a thrust duration of 3.45 seconds, this 29 mm engine delivers the kind of long-burn, high-performance experience that supports real-world applications of STEM concepts.

Its 8-second delay allows rockets to coast to their maximum altitude before deploying recovery systems, giving students the opportunity to observe and analyze optimal launch timing and flight path dynamics. This makes it especially effective for experiments that focus on trajectory tracking, aerodynamic testing, and high-altitude recovery strategies.

Whether used in a classroom, STEM camp, or competitive team setting, the F15-8 provides dependable performance and consistent results. Its high-thrust output is ideal for heavier or drag-intensive rockets, expanding the kinds of builds and flight profiles students can explore as part of hands-on learning.

Estes Education is committed to supporting science and engineering education with safe, classroom-ready tools—and the F15-8 engine is no exception. It opens up exciting new possibilities for students ready to take their rocketry knowledge to the next level.
