Yes, the motors back in the '60s had paper end caps. I actually have a Centuri C6-0 with a paper end cap in it. Collector's item, no?

Even with the clay caps, I stuff some wadding or dog barf in each motor of a cluster. Learned that lesson the hard way many, many years ago. Miss the Centuri Sure-Shots (originally RDC (Irv Wait, blessed be thy name)), but the Quest Q2G2 squib is wonderful. I fly with DARS, the Dallas section, so their launch system will handle four Estes igniters or "starters" without a shrug.

Okay. I am over 60. I need the SEMROC GT now, or pretty soon, or before my expiration date.
