Nice looking ship Hitech. This is my dream airplane at this point when I'm starting to figure out I'm not gonna be able to afford the Pilatus PC-12. I rebuilt a little Luscombe the other year but its a toy and seems a lot smaller than the one I had many years ago.
A friend I spray with also wants to build one but we live about 5 hours apart and haven't figured out labor and custody issues.
The Eggenfellner outfit makes a slick looking power package for RV series aircraft.

There is a guy in Switzerland who is building an RV8 and has an interesting construction site that's kinda fun to hang out at. He has elected to use one.
Did you build it?
