Hello, this is my first time posting, please inform me if this is the wrong place. I'm working on building my first scratch built rocket, and I have a few questions. Firstly, I'm building motors for it. I'm very aware of the dangers of this and treat those motors like nitro. Anyways, I'm putting a store bought high thrust G motor in it to test the aerodynamics and dual deployment, I'm worried when the full size motor is introduced (Probably a mid I motor with a long burn time) that I'll destroy my fins. They're 1/8 inch pine (Very beefy, I think) but they have a subtle airfoil on them. Software and calculations say ill be fine, but from the experiences of others, do subsonic fins have a tendency to rip off at transonic to supersonic speeds? Additionally, are dual deployment systems hard to use? It's a perfectflite stratologger, and I did order the data kit for it.
