However, AFAIK BT-101 is not a particularly common tube to have lying around the workshop. Most people building rockets in that size today would probably use the LOC 3.90 heavy wall tubing instead. I actually have plenty of tubing on hand from BT-4 (10.5mm motor tubing) al the way to BT-60 on hand for scratch projects, but the not larger diameters. I tend to buy those as needed for specific projects.
