Most of my propellants are sugar based. I work
with Sucrose, Dextrose, Sorbitol, and Erythritol.
Of the four, I favor Dextrose for most of my
work.
It is nothing more than personal preference. All
are wonderful fuels and serve different purposes.
Sucrose:
Cheap and readily available. It is easy to
work with using
Jimmy Yawn's method.
Dextrose:
Also cheap and readily available.
You can find it at your local brew shop
or health food store. It can also be ordered
in bulk from
Honeyvillegrain for around
$1.00 per pound including shipping.
I use Dextrose to make my C-slot
grains because it is easy to pour into the
casting tube. I also like the quick set time.
Sorbitol:
I also get this at the local health food store .
It has the advantage of a slow set time. It works
great when you are still learning how to cast
your
grains. It cost a little more, and has a
somewhat slower
burn rate at higher pressures. Learn more
about this by visiting
Richard Nakka's
site.
Erythritol:
This is the fuel championed by Scott Fintel.
He used it to fly to over 29,000 ft.
It has a slow burn rate and can be used when a
long
burn motor is desired. Learn more about
Erythritol by visiting
Scott's
Website.
