I never messed around with Zinc / Sulfur aka "MICROGRAIN" . . . I have heard that static electricity could set it off, right in your face. http://www.raketenmodellbau.org/repository/archive/704 |

Here https://www.youtube.com/watch?v=gdEije_CvQg is a 1/2" ID KNSU motor built according to specifications in David Sleeter's book, Amateur Rocket Motor Construction.
Produced almost 2 LBS peak thrust on 9 grams of fuel. Not bad and I still have all my fingers. |

KN = Potassium Nitrate SU = Sucrose (confectioners sugar) Sleeter refers to this fuel as KS in his 2004 book, which also contains a small percentage of sodium bicarbonate (baking soda) to reduce the burn rate. There is no sulfur in this formula as there was in the formula referenced in the Bravo Niner booklet and as originally published in Sleeter's earlier efforts. Sleeter uses a dry rammed method and the motors produced are core burners. I don't wish to disclose Mr. Sleeter's exact formulas as his work is copyright protected. Used copies of his 2004 book is available through Amazon by various vendors at inflated prices. |

Thank you. He sent me a couple of his "The Incredible Five-Cent Sugar Rocket" reports and Micro-Sonde model rocket plans a little while back. I used to have his book on making black powder motors.

You are most welcome. Hmmm, "....a little while back". Like how long ago? The reason I ask is I haven't or seen much about him in a good while. He seemed to have vanished from the mid-nineties until he published his masterpiece in 2004. I wonder, is he writing another book? |
