I'm building a model rocket, and I'm trying to find a good fuel. I've done a lot of research and I know about r-candy and the aluminum-ammonium fuel, but I was wondering, before I made any of these, if I could use All-Purpose Flour instead. From what I've seen, it is highly combustible, and I think it would do a good job. However, it appears to burn slower than r-candy. Would it still burn fast enough to get a rocket launched? I also noticed that it doesn't pack easily, and I'm looking to make a solid rocket motor. Could I use water to pack it into the motor tube, then leave it to dry for a few days? Or could I pack it some other way?
