Thumbs up Problem solved

Hi again,
I just wanted to let you folks and any future readers know--it WAS a chemistry problem. Perhaps burning Calcium Stearate was the problem, or perhaps there was something else odd going on. In any case, the problem was the stump remover.

After various experiments, we finally gave up and bought some lab grade 99.999% pure KNO3. We were not disappointed, as it worked quite well.

Thanks for your time and input! We are especially glad that you mentioned the risks of PVC casings.

You might try http://www.rocketryforum.com/ for additional information. They are always extremely helpful and courteous, especially when it comes to formulas. Just tell them "Uncle Ted sent me."

Ted, that's a great idea.
I'm sure they will be extremely helpful in advising this endeavor.

I'd advise against it. Those guys were pulling your leg but asking for help at TRF. If you ask the question you asked here at TRF they're going to jump all over you in 2 milliseconds flat (and not in a good way).

FYI, I don't allow talk about experimental motors here either, but since you basically answered your own question I let it be.

Apparently, our newbie forgot to mention Uncle Ted. LOL!

I'm REALLY surprised they were as gracious to him on TRF as they were.
I expected them to go off like a short-fused grenade.
