Now, last time I was here, we were all still using the ukrocketry forum and there were some experienced model rocketry fellas here. I've recently been studying Hybrid rockets and am completely obsessed. However, I could obtain LOx or N2O for oxidizers if I really want, but in this book I have it states that either the oxidizer OR the fuel can be liquid. So my question is, could one use something like beutane or propane as the feul and have a pressed oxidizer grain of Ammonium Perchlorate or perhaps even Potassium Nitrate? Anyone ever thought of doing this?

Alrighty, well unfortunately I can't actually post much info about composite motors. I am still in the trial stage of these types. I've been making and testing various silicone2/perchlorate based composite propellants and plan to (hopefully) launch two different types today. I am really curious if anyone has any information on Urethane bound composite propellants. I've been attempting to get a working Ammonium Nitrate/Urethane composite, but have had no real luck so far using an 85:15 ratio, I currently have a drying cast of 90:10. Has anyone had experience with this, or know what the proper stoicheometric ratio would be for NH4NO3, or perhaps KClO4?

-of course as the subject dictates all discussion about any composite propellant is welcome
