propellant test

what if you up the sugar content and do away with the charcoal?

@ccexpressable I tried that at first, but it was harder to ignite and didn't get it to burn as well. If you don't have charcoal then sulfur would also help it burn better.

Nice burn, nearly smokeless.

What's the composition? 5*

[Kelfam48230]

60% KNO3

10% sugar

5% aluminum powder

5% charcoal

20% bondo fiberglass resin

Let me know how it works and please post a video so I can see how yours works.

The propellant can produce something like 133 isp. And it is really cheap.
