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.

Carl also liked Centuri. Their tubes were/are just a little thicker.

Another reason why he and I got along so well.

Good to hear from you, Miss Sheryl! I think of you and your extended family, and pray for you often!

First post I've made in quite a long time! Yes, I'm still alive...

And good to see Mr. TZ still kicking, too. And still doodling with rockets and RockSim. At least one of us is, anyway. I've just about forgotten everything I never knew about the program.

Agreed. Much prefer ST-10 to nearly anything smaller. It just has... that feel to it
