Pyrodex also requires neither permit nor storage, and has been used
successfilly for ejection charges.
from "Use Pyrodex "P" Instead Of 4F Blackpowder"
The topic has come up from time to time about using Pyrodex instead of
4f black powder for ejection charges. We have found the secret to using
Pyrodex as a direct substitute for 4f black powder after conducing a
series of ground tests and successfully flying 11 rockets with various
sized ejection charges all of them using 100% Pyrodex instead of black
The Pyrodex to use is Hodgdon "P" or FFFG Equivalent for ejection
charges in PVC pipes sealed on one end or phenolic tubes sealed on one
end. The sealed end is usually a PVC fitting with a hole in the middle
for the electrical wires to the e-match or flashbulb. If you use a
flashbulb, make sure the tip of the flashbulb is in the Pyrodex powder.
Flashbulbs do work with the Pyrodex as we had 100% success in ground
tests and two flight tests.
We used an equivalent volume of the Pyrodex "P" as a substitute for the
4F black powder. After putting the powder in the open end of the tube,
we would put a wadding material in the tube. We filled the rest of the
open tube with wadding so that the powder stays at the base of the tube.
On the open end of the ejection charge tube, we would normally use
masking tape to seal the tube when using black powder. For the Pyrodex,
we used electrical tape to seal the tube. We put one piece across the
open end of the tube with the ends of the tape going down the side of
the tube. Then, we put another piece of electrical tape across the open
end of the tube 90 degrees to the first piece with the ends going down
the side of the tube. Looking at the end of the tube, it makes a cross
pattern. Finally, we put a piece of electrical tape circumferentially
around the tube at the end where we had put the electrical tape. This
piece of tape goes over the ends of the first two pieces of tape. That's it.
We are flying just with Pyrodex now as it does not leave the residue or
stink you get with black powder. Also, it is generally easier to obtain
