Thumbs up Phobos V -- 18mm version

Simple but different. I like it.
John and BEC,

Look at the deployment velocity on a 1/2A6-2! That's almost perfect!

--Not to mention some good performances on A, B, and C motors, too! And all that *with* a great big SE-14 screw eye, as well!

BEC, it looks like the 18mm stability margin is 1.40 calibers on a B6-4, and 1.25 on a C6-5.

Enjoy, everybody!
