Good--thank you for reporting their ejection charge mass reduction. The original Quest also had motor problems, which to their credit they quickly corrected. My first Quest motor, an A6-4 (black...

That's the very term that came to me as I read Bernard's posting above, in a new saying: "Being an involuntary beta tester is a b---h!" :-) It's possible that in their enthusiasm to get the Q-Jets...

Thank you for posting those measurements; I had suspected that they might have "meant the loaded [with expansion] size," but wasn't sure. I never saw a spiral-wound mini motor, but I think that was...

Not having bought their kits steadily over time, but at intervals, that may have been a "phase" they went through. With one exception (described below), all of the Quest kits that I've bought have...

When the dimensions (0.69" [it may be 0.690"] x 2.75") were given in the Estes catalogs, I wonder if they were for the casings before they were filled? Your midsection (propellant section)...

Thank you--that's interesting, and it's good (for their own kits, too) that future Q-Jets will have slightly narrower casings.
