This is a propellant formula that I received from Kelfam48230 and consists of:
60% KNO3
10% Sugar
10% Aluminium - Slightly more than original no reliable source of charcoal.
20% Polyester Resin

  • This propellant was created by Scott Fintel go to his website and look in the "experimental propellants" section.

  • yh not bad, but ventsi's right, take out Al, put in Mg, it would defonately make it better

  • not bad mate

  • Hmm, not bad for a start of a propellant.

    If you want to make it better, I'd say take out the Al, and add in 5% Mg, that should take care of the "chuffing". Also 1% lampblack should give it a smoother burn. Not so sure about the sugar and if its helping or chocking it up either.
