I' am also in Naperville, building an RV-10 with an Egg turbo. We should get together and inspect each others projects. I can be reached at 630-308-7476.
Would love to see your 10 sometime, my friend is almost up to the firewall on his rv7 in Aurora. I am just ordering kit #2 of my 12 so its going to be awhile till wheels up, but its amazing how well though out this kit is.
