Firstly, I've never done anything with model rockets, so don't have any experience in this area. However, recently I've been reading about sugar/KNO3 as a home-made propellant that's not bad.
I was wondering whether it would be possible to make a similar propellant (using KNO3 as the oxidiser), but using paraffin wax (candle wax) as the fuel. I would have thought that the wax would have plenty of energy to provide as fuel and the lower melting point would mean that it's much easier/safer to cast. However, there isn't much mention of this on the internet, so I assume that it wouldn't work, otherwise people would be using it.
Can anyone offer any ideas/experience as to whether it would work or not and if not, why?
