24 mm to 29 mm Engine Adapter

The Estes 24 mm to 29 mm Engine Adapter gives educators, STEM leaders, and youth rocketry programs greater flexibility when planning model rocket launches. By allowing compatible 24 mm engines to be used in rockets with 29 mm engine mounts, students can explore additional flight configurations without permanently modifying the rocket.

Explore the Impact of Engine Selection

Use different compatible engines to help students investigate how engine selection can influence model rocket performance. Comparing flights can create engaging opportunities to discuss thrust, total impulse, rocket mass, altitude, and other real-world STEM concepts.

More Flexibility for Your Rocketry Program

The adapter is compatible with Estes 24 mm C11, D, E, and E30 composite engines, along with many other 24 mm composite single-use and RMS motor systems. This expanded compatibility gives educators and group leaders more options when selecting engines for different rockets, launch goals, and learning activities.

Reusable for Future Launch Activities

Each package includes two reusable orange paper adapter tubes designed for simple, dependable use. Keep them with your model rocketry supplies so your class, club, camp, or youth organization has more options available when planning future launches and STEM activities.
