This may be a dumb question but here goes. Back in hobby with retirement and really having fun designing on Open Rocket and then building and flying. To date I have simply followed the Estes BT system when buying and fitting out nose cone and body tube for my designs.
But I have noticed but not focused on the vendors who have, for example, a 2.56 inch body tube. I guess my question is whether these sizes correlate to a BT size … or is there a whole other system I need to explore that matches up body tube and nose cone sizes for design purpose.
Thanks
