It's worse than that. I was thinking about using metered liquid propane about a week ago for large cannons or high hybrid mixes as well.

You may want to do a bit of research first Gunner, start with the Hybrid showcase.
May i ask what types of cannons you have built before?

And no, no fan.

... last night about why spudfiles is a good forum. And he said that those cannons are weak. Then I said something that was probably true. "Dude, if ... cannons, we could take over china". And now I think that just Larda's Hybrid could do the job :twisted:

thanks for the quick response. i like the size and power of full scale cannons. Massive hybrids were built by DR, jesse spellman, etc...both of which were sch80 pvc. I would like ...

True. Its about the same thing that most combustion cannons perform better at cold weather, since more fuel can be put in then. More ... This all does make me think that the perfect weather to fire a combustion/hybrid is dry, cold and high-pressurized weather. But, good thinking! This will ...

just wondering about the science of a hybrid thx

A hybrid is simply a combustion where the contents are already under pressure before firing. Have a browse through the finished cannons section, there are plenty of relatively simple designs you can copy.
