You are kind of treading on sensitive ground here - the designers are rightfully pretty careful about their designs.

Having said that, I doubt that any of them would give you CAD files, so you would have to purchase plans and trace them yourself.  And most of those are going to be larger scale - 20 and 25% scale.

Two places to start would be Nick Zirolli Plans and Meister Scale.  I would suggest that you talk to the owners and explain what you are doing and why, and offer to purchase the plans.  You can look for Brian Taylor plans too - sold by Traplet (they are supposed to have an outlet here in the US).

There are laser-cut kits for these already on the market, but at the larger scale than you are looking for.  Retractable landing gear, tail hooks and cockpit kits are available for those larger kits too.  Which begs the question - why go through all the work of cutting your own if one is already available, albeit at a larger scale?

Walker,

When you buy plans they usually have a few separate sheets of formers, ribs and various other shapes that are to be cut, to build, or help build, the aircraft you are making.

Cheers,
