Who would have though metal fins on a rocket like this would cause an issue
Though I think on rockets like this, there is a place for them.
and see no problem with the build.
But I have to yield to the rules and regs, So I have started to rebuild with Carbon/Ply fins
This time around, the fins are laid up in a 3Ply/3Carbon/3Ply/3Carbon/3Ply arrangement, with 2Carbon to be added to out sides later.
even with this stack, I've managed to keep the thickness to 3.5mm, reducing from over 5mm on the original fins, giving me a 30% reduction.
great thing is, I can reuse the original booster tubing, which I'll get some pictures of the hack and slash on that over the next day or so
