Hello,
I have designed a slightly silly, large BT-80 rocket and am concerned about its strength as it seems that BT-80 can be weak due to its large diameter and thin wall. The body will be four 30" length ASP T-80H tubes which have a wall thickness of 0.031" or 0.775 mm according to their website, and the nose cone will be custom 3D printed out of a lightweight PLA and should weigh ~60 g. The parachute is 45" in diameter so it will only hit the ground at around 4 m/s or ~13 ft/s to avoid having the tube to kink on landing which I've read can be an issue with large BT-80 rockets. What is the maximum thrust this thing should be able to take?
Here is a photo of it modeled in OpenRocket (the file for it is also attached):
Note for the OpenRocket file: The engine mount is an Apogee BT-80 quick-change mount.
