Hi Rob (and welcome)! I'm one of the builders in Cedar Rapids Bob mentioned. Of the 2-3 projects I know of in the area, I think ours is the farthest along (you can sit in it and make airplane noises!

) but it's still a ways out from actually flying. There is one flying RV10 here at KCID, but the guy isn't always around town this time of year.
Feel free to visit our blog (link below, sorry it's not being updated quite as often these days) or send me a PM if you're interested in stopping out sometime to see the project. I'd be happy to walk you through the build process, set a practice rivet or two, or do my best to answer any questions you might have. Let me know!!!
Cheers!
-Mike
PS- You're also more than welcome to stop by our EAA Chapter 33 meeting this coming Thurs 2/4 at KCID safety center. It's not the biggest or most active chapter in the country (working on changing that!) but there's a few RV-ers that always stop out. I've been to a QC meeting before and they seemed like a great group too!!
