Matt,

Thanks for the reply. As someone who reentered the hobby in 1989, North Coast was a big part of the move to high power. My North Coast catalogs of the period ae well-worn, and my NCR Corporal was my first high power rocket, built in 1991.

I have flown a few 20+ year old composite motors with good resuts. I was wondering if you have a feel for how the Darkstars are aging and if thought was given to that when they were designed.
