Rocket Proppelent

And small model rocket engines sizes a-d and maybe e use a propellent that is very close to black powder and no rocket engine uses sodium adize as a main proppelent that i know of.

The diference over those two weapons, as far as i know it s that the carl s is more like an rocket launcher, and the mm is realy an recoiless cannon, where the proppelent is..
