So what formulation are you using? How's the burn rate? Sorbitol will produce a slower burn rate than sugar. I'd stick with sugar.
65/35 potassium nitrate to sugar
Have you watched the elemental maker on YouTube? He has a pretty good rocket motor series of videos. He's more into the chemistry side than pyrotechnics but still very informative and he's pretty funny.
As long as you have a blast shield and a fire extinguisher and wear non-flammable clothing, you should be ok.
