4″ Airframe Tube Set

A two-piece 4-inch diameter tube with a coupler to splice the parts together to make a 36-inch long airframe. Allows you to make your own rocket designs like the professionals but that can be taken apart for transport to the launch site. Made from high-quality kraft paper, with a white overwrap. You can write on the tube with a pencil, or color them with markers. Very tight spiral seams, so it is easy to get a smooth surface finish.
