BT-80 Model Rocket Body Tube
The BT-80 model rocket body tube is the largest standard body tube for model rockets. Care must be taken in the design of rockets with the BT-80, as the large diameter of this body tube compared to the thickness of the wall of the tube can lead to unstable designs. Often, a BT-80 tube coupler is used to reinforce the strength of a rocket using the BT-80 body tube.
