One thing, if you get over the anti arithmetic bias, Wild Bill's nomographs and equations can let you design a plane that is pretty far from the norm and be confident that it will fly well.
This FW-190 is very near scale. The wing has about a 1in. wider chord, but the correct shape, including the angled tips. The stab is 1/4 in. wider than scale(for the scale wing), and the fuselage was slimmed down in height an inch or so. The dihedral is pretty close to scale too. Using the light Brodak 40 put the CG right where planned and the thing flys much better than I expected for 460 squares and 29 ounces.
