I've never attempted to make a sugar propellant end burner but I have often
given it thought. Here are some of my thoughts:
1) A conical propellant surface, rather than a flat surface, would greatly
increase burn area at no expense to the burn time.
2) PVC casing may be the ideal choice. I would expect ablation of the
casing surface would keep it reasonable cool, and bearing in mind at low
pressure, a thin wall is all that's needed so you can afford to ablate away
much of the wall. Also, PVC is very lightweight.
3) Brown iron oxide may be the key to getting sufficiently fast burn rate
to produce useful thrust.

has anyone dabbled with end burner motors? i know that it would cripple
the thrust that the quantity of fuel could produce but it seems like it
should work.
