BT-80 Body Tube

Built from sturdy spiral-wound kraft paper, the BT-80 Body Tube is a commanding 23.5-inch (59.69 cm) main tube that’s perfect for single-stage giants or ambitious multi-tube projects. Use it as a powerful standalone tube or pair two BT-80s with our BT-80 Tube Couplers (PN 3178) to unlock heavy-lift capability for 24 mm and 29 mm engines.

Designed for serious hobbyists and TARC teams, this tube mates easily with our Laser Cut Ring Set (PN 068254) and accepts NC-80K or NC-80B nose cones for competitive egg-lofting builds. Durable, easy to finish, and built to scale up—this is the backbone for your next high-performance rocket.
