Most available oxidizer for beginners is probably KNO3, but it is hard
to make composite propellant from it. Is it wrong to think that
components used for composite (epoxide resin etc) are inferior to sugar
as fuels - and "candy propellant" or even black powder with ammonium
perchlorate instead of KNO3 would be very powerful propellant? Any
experiences from folks having access to perchlorate?
