I have 5 combustion guns all which have chamber sizes no smaller than 170 cubic inches. The Mini 8 has a chamber volume of 83 cubic inches. It's got all the mods such as chamber fan, ignition, metered fuel delivery, and on board tank. Ill try to post some damage vids.

Hi there fellow combustioneer!
Do I recognize a check valve for rapid venting?
Some more pictures would definitely be nice.

What's Up mark. what you see here is a 1.25" full port ball valve. this Canon can exhaust its chamber in about 6 seconds. I'm running a 12 volt, 60 millimeter fan. my electricity source is an 18 volt rechargeable battery. This launcher runs very clean. there is very little unburnt fuel if any left in the chamber after combustion. the obvious goal is to reach stoichiometry.
