BT-80 Body Tubes (2 pk)

The Estes BT-80 Body Tube 2 pack gives educators, STEM leaders, and student rocketry teams a versatile foundation for larger model rocket projects. Each 14.2-inch tube is made from spiral wound Kraft paper, combining lightweight construction with the durability needed for hands-on building, testing, and repeated design exploration.

Turn Rocket Building Into an Engineering Challenge

BT-80 body tubes give students the freedom to move beyond predetermined designs and apply engineering concepts to rockets of their own creation. A single tube can form the foundation of a large single stage rocket, while compatible BT-80 Tube Couplers allow students to experiment with longer designs and evaluate how changes in size, mass, and configuration affect performance.

Built for TARC, Payload, and Egg Lofting Projects

The generous BT-80 diameter makes these tubes especially useful for TARC teams, payload experiments, and egg lofting challenges. Students can pair them with compatible NC-80K or NC-80B nose cones and other Estes components to develop rockets around specific mission requirements, encouraging planning, iteration, teamwork, and creative problem solving.

Explore 24 mm and 29 mm Motor Configurations

When combined with the appropriate Estes laser cut rings and motor mounting components, BT-80 body tubes can support designs using select 24 mm and 29 mm engines, including C11, D12, E12, E16, and F15 options. This flexibility allows educators and team leaders to create increasingly advanced projects as students gain confidence and experience in model rocketry.
