Shulzie,
I loved Jim's "Spirit of America". Jim let me fly it after the 1969 Team Selections. He did not have pictures of the airplane, so I gave him a picture about a year before he died. I wish he could have seen your pictures.
It is a shame that details are not available, because I would have loved to build one.
Paint schemes can be a real hang up. It seems most look like the next one.
Not being overly artistic, I am certainly not an expert on the subject.
I personally feel that it should look more like a real airplane. So many stunters have very busy schemes, but there are only a very few full size airplanes like that.
The jet style airplanes usered in an era of over doing it. I worked most of my life in the Aerospace industry where we shaved rivet heads, and hid panel separations for aerodynamic reasons. While impressive to look at, I have never seen a jet airplane with every rivet head painted black.
If the airplane is in the style of a fabric covered airplane, there are very few access panels, and generally the only fasteners are at the wing to fuselage fairings, the cowl, and the few access covers.
Exhaust stains can look good, and dirt at the panel separations look good but can also be over done.
I look at trucks and race cars, and also everyone else's stunter. I like a tastefully done, well detailed airplane. But in the end, it is up to the eye of the beholder. Some will like it, some will not.
My "Jerseyan" color scheme is directly from the Purex sponsored Indy cars that Robby Buel and Sarah Fisher drove several years ago. I love that look and just had to use it.
Look at Randy Powell's new "Something Drastic". It is a perfect example of Simple, Elegant, Tastefull, and not over done.
