Default New Design - Centuri Italian Sea Killer 1.15X

I much more greatly prefer Centuri/Semroc ST-10 to ST-8, simply because there's more room to attach a Kevlar shock cord anchor to the motor mount.

Hence, my "slightly bigger than before" version of this rocket. I included a color kitcard photo from scigs30's build of the original model.

EDIT: I just added the fin patterns that I redrew in Paint Shop Pro.
