Interesting thread. I recently finished a somewhat modified Touche, a Dave Platt design from a very old Pica kit. All through the build I kept thinking "this really looks like a model airplane." Now I see why I thought that: Big wing with a fat symmetrical airfoil, long thin fuse, and a small vertical stab (made up for by a lot of vertical area under the tail). Not that it was a converted control line plane, so far as I know, but I'd bet that it looks that way because the designer had a notion of how models should look. The looks may have been at least part of what influenced me to finish it with silkspan and dope instead of a film covering.

(Haven't flown it yet because flying season is over here.)
