RE: Mini Funtana Crash Rebuild and Conversion to Gas
For an idea on how to set up the CF pushrods, take a look at the DEPS system from [link=http://www.centralhobbies.com]Central Hobbies[/link]. The system is probably too big, but perhaps you could scale it down for your purposes (and use just one instead of 2 pushrods). It's a very solid control setup and is used by a large portion of the pattern community.
