I was wondering if anyone could give me any advice on this. I've been flying a LOC/Precision IV for a bit now and I love the rocket. However, I think I'm ready to move on to my level 2 certification, but I also don't want to spend $300 on a kit. Right now I am planning on copying the LOC IV kit. By that I mean buying a Public Missiles fiberglass air frame with precut slots, Public Missiles custom fins (the same shape as the LOC IV's), and a couple of centering rings and a motor mount tube. This would allow me to reuse the nose cone, parachute, shock cord, and the instructions from my LOC IV kit without any additional modification.
Like I said, I would like to get my level two certification. I haven't modeled this in OpenRocket yet, but the aerodynamics and CP should be the same right? All I need to worry about is the center of gravity being changed and the added weight so I might need a bigger parachute? If I want this thing to go at least mach 1 how thick should the fins be if I don't want to do tip to tip fiberglass?
