So, I have this giant (9" in diameter) plastic pig.
I was planning on putting a body tube up his... But after running some calculations, the finished rocket will be upwards of 10-15 oz. The pig itself is 5 oz. Add parts and clear plastic fins, and it really is... a pig.
Sounds like it will require an E+ engine to gain any sort of reasonable altitude. I was planning a standard Estes type BT-60 main tube, 24mm engine tube with rear ejection. Stop laughing.
Will a BT-60 handle an F? G? Should I go to a 29mm engine? How much power can I use and hope it won't shred? I could go to a .1" wall thickness, but that just adds more weight.
