Welcome Chief!
Just wish I would have seen this post earlier. You are more than welcome to ask for some help finding info. There has been a real hailstorm recently with government regs. so some folks are a little touchy, but that's ok.
As I'm sure you well know from your Navy days that the powers that be can really screw things up for us regular guys, even if we just go near the edge of a rule.
Richard Nakka is one of the most well respected guys around when it comes to sugar motors. Here is his website with more than enough info to keep you reading for a while. There is even formulas for bp replacements [crimson powder] that I know work well.
All you questions about sugar motors, formulas, rockets, regulations etc., will be found here with a little digging. It represents years of research and data. I bought his CD's to be able to view anytime.

The club I fly with in South Carolina had a good following when it comes to candy Motors. They have successfully flown M size sugar, and all sizes on a regular basis. All with in the constraints of the law. There are many groups out there doing the same.
Please enjoy the data from the link and come back and visit with us!
Ps I just saw your from Florida. well your pretty close to another great researcher into sugar. Jimmy Yawn flies with us in SC occasionally, but is a regular in North Florida. Here's a link to his sugar site...both sites a indexed very well..to go direct to ejection questions. Jimmy's E-mail is at the very bottom of his front page. I'm sure he can tell you where the "candy" fliers meet monthly to fly.
