Hey folks, can someone who builds and uses Fast Gun cannons write an article about how they work? Or, is there a website with a good description and (more importantly) a diagram of how the basic Fast Gun cannons work? I am talking with some RC tankers on another forum who want to replace the airsoft cannons in their tanks with something more capable. I have already warned them about the safety issues, now I am talking about the various designs I know of and I don't have a good description of the operation and manufacture of Fast Gun cannons. Any help would be appreciated. The RC tankers are here: http://www.rcuniverse.com/forum/m_5403595/mpage_1/key_/tm.htm
