Precision Cut Kits
Laser cutting
I originally got my set of laser cut ribs and formers from Tank's Hangar Aircraft Modeling, but Tank's has since gone out of business. I recently learned that Precision Cut Kits offers a kit version of the George Miller A-10, which includes the same laser cut parts plus all of the wood needed to complete the plane.

Doug's George Miller A-10 Build Thread on RC Universe
My friend Doug is also building a George Miller A-10. He's posting progress on RC Universe. From the get-go, we've been almost neck-and-neck in our progress. He's attacking some of the build issues different than me, so it's a good thread to check out.
