  • dont know how much i can say about this topic, but for use on a spud cannon i would extend the probe more into the center of the cannon. when using traditional aerosol propellants i have had poor luck with them mixing well leaving you in a situation where it wont fire… i took a few inches of ~1/8" rod metal and bent it into a longer spark plug to get it into the center of the chamber… otherwise they work great!

No public wish lists :(
