i'm still conducting heavy research about my first HPR, and this question is regarding the strength gained by through the wall fins, and tip to tip. If i'm making a minimum diameter rocket, i can't through the wall, but i can tip to tip. Through the wall gives the fins more attachment and durability, but not supersonic capabilities by itself. I'm wondering, if i make a minimum diameter rocket with plywood fins, and i tip to tip without glassing the fins separately, will the strength go down a lot? I really just want to make sure those fins stay put and don't erupt off and give me a failed cert and a heap of twisted and smoldering stuff.
