Estes 30xx CS
 

While building a data base over the past few days to get a handle on things, I've noticed that the rockets that start with 30 are the bring backs (Classic Series) Century kits.
But not all packaging reflects or shows the CS label that have the 30xx number.
For one, the Star Trooper doesn't show this.
Maybe Mike can chime in here and give us a little enlightenment on this.
I'm currently trying collect at least 3 of each. 1 to leave to each of my 2 son's when I'm gone, and one for me to build and fly once and put in my collection.
It would also be nice the have a 4th for more than one flight.
Has anyone else noticed this that all 30xx numbered kits are not marked as CS, but are?
