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.

Size: 23.5 in (59.69 cm) length for impressive single-stage rockets and large-scale builds.
Coupleable: Use BT-80 Tube Couplers (PN 3178) to join two tubes for extended length and increased payload capacity.
Engine Compatibility: Configure for Estes 24 mm and 29 mm engines with appropriate motor-mount components.
TARC Ready: Combine with Laser Cut Ring Set (PN 068254) and NC-80 nose cones for egg-lofting and competition designs.
Material: Spiral-wound kraft paper—lightweight, strong, and easy to finish or paint.

Overview

The BT-80 Body Tube is a heavy-duty, spiral-wound kraft paper tube measuring 23.5 inches (59.69 cm) long—ideal for building show-stopping single-stage rockets or scaling up into multi-tube configurations. Its robust construction balances light weight with the strength needed for high-altitude flights and larger payloads. Finish it, paint it, or leave the kraft look for a rugged, authentic aesthetic.

Modular design for extreme builds

Pair two BT-80s with our BT-80 Tube Couplers (PN 3178) to create an extended main body capable of accommodating larger motor loads and bigger recovery systems. This modular approach makes it simple to experiment with length, payload bays, and staging options while keeping structural integrity front and center.

Engine flexibility and motor mounting

When used with the Laser Cut Ring Set (PN 068254) and proper motor-mount components, the BT-80 can accept Estes 24 mm and 29 mm engines—opening the door to single 29 mm E16 or F15 engines, 24 mm C11/D12/E12 engines, or even clustered 24 mm configurations for added lift. The result is a versatile platform for both high-power experimentation and competition-level flights.

Competition-ready features

TARC teams and competitive builders will appreciate how easily the BT-80 integrates with NC-80K (PN 71035) or NC-80B (PN 3168) blow-molded nose cones for reliable egg lofting and recovery. With laser-cut centering rings and recommended engine mounting hardware, you can focus on tuning performance and payload safety rather than structural fit.
