I know this is a WNW thread, but I, too, plan to get the Copper State offering. The CAD images that are available for both kits show to me that the Copper State offering is showing more detail, "under the hood" especially. As an example, I especially like the way Copper State is proposing to show the entire fuel tank compared with WNW. There also appears to be allowance for showing off this internal detail near the engine that WNW is not showing in their CAD. I also like how the framing of the fuselage internal structure from the cockpit forward is separate from the wall of the fuselage, whereas, the framing is on the wall of the WNW offering. Just my $0.02.
