...at least one way anyway.

I've always wanted a scale appearing WWII B-25 "Mitchell" stunt model. I've gone over designing and building a B-25 in my head for years now, but I just haven't gotten around to building one. There are some existing designs, but none as scale in appearance as what I'd like. Paul Delgatto's design is very close, and a perfect size, but it's just not quite what I'm after. For one, mine would have to have the proper gull wing, Delgatto's doesn't.
(The following is copied from a reply that I made to Pat King in his F-82 "Twin Mustang" announcement in the forum Vendors Section. While writing, I thought it may be of interest to some others.) I'll roughly describe my
hypothetical B-25 design here. This is how I designed and built my 64" PBY Catalina stunt model...
Depending on the chosen full scale subject, there will always be slightly different ways to modify and end up with the desired result. While designing
think scale, but pay very close attention to the "stunt devil" sitting on your shoulder and let him influence things all the way through.
Starting with a "clean sheet" stick diligently with true to scale outlines but play with size relationships between various components. First, pick a desired wingspan, say 56", and print off an enlarged full size scale three-view at that dimension. Be sure to start with a detailed, quality three-view, like on the order of a Paul Matt drawing or similar. Save and set aside the fuselage outline as is. Then, in the case of the B-25, "cheat" or add to the overall wing chord slightly, including the flaps. This is to sneak in some additional wing area but you want to stop before taking away noticably from the scale outline or appearance. Do the same with the stab/elevator and also add in a little more span, essentially you're just enlarging the entire stab/elevator assembly.
Now, take a clean sheet of paper, draw a long horizontal line and mark in the desired moments using the "new" wing/flap/stab/elevator chord dimensions. Take your saved scale fuse outline and lay over it. You will likely need to adjust the fuselage length to fit things where you want them, just make adjustments for the best overall scale appearance/stunt compromise.
At this point thrust lines and wing/stab height relationships can also be subtley adjusted without detracting from the scale appearance. You may find that you'll want to "section" some height out of the fuselage outline, or not. Go for it if necessary, but keep the top and bottom outlines true to scale. Spend good time getting the fuse proportions just right in comparison to the flying surfaces to maintain the overall scale look of the model. What you should essentially end up with is a scale fuselage with proportionally larger flying surfaces, all with scale outlines.
This certainly isn't a complete description of the process, but just my own general approach and thought process. It is very possible to design a model that appears very scale but will also be a suprisingly good stunt model. The best of both worlds in my opinion.
