Overview

Turn a student design sketch into a hands-on engineering project with the BT-70 Body Tube, 19.5 in. This spiral wound kraft glassine tube gives educators and youth leaders a practical component for custom rocket builds, competition preparation, and model repairs.

Put Measurement and Planning into Practice

With a 19.5-inch length, 2.175-inch inside diameter, and 2.2147-inch outside diameter, this tube provides a concrete way to explore dimensions and component fit. Have students use these measurements to select compatible parts and explain their choices before assembly.

Support Student Competition Teams

Use this BT-70 body tube as part of a scratch-built rocket or a team's next design revision. Students can plan around its full length or measure and cut a shorter section to meet their design needs. The same tube is also used in the 009922 Competition Rocket Starter Bundle.

Keep Your Athena H Projects Moving

This tube is a replacement for the body tube in the 009725 Pro Series II™ Athena H. Keep one available for repairs so a damaged tube can become an opportunity to practice rebuilding, inspect component fit, and prepare the model for future flight.
