Hey Tom,
Welcome to the club. I am just down the road from you in Navarre. I'll be starting a Cozy in the near future. There are two active builders in the area that I've found. One is getting close to mounting his engine, and the other is still working on the fuse. Both have been very receptive to my questions.
The local EAA chapter (chapter 485, http://www.eaa485.org/) meets Tuesday at 7PM at Ferguson Field, come on out. They seem to be heavily aluminum oriented, so you can get that perspective. If I make it to the meeting I'll bring my plans so you can take a look at them.
Ryan.
