The cutaway drawings are definitely a great idea, and I plan to have some done in the future. At $500+ for each we would probably not be focusing on individual member airplanes, but rather on representative versions of the individual models.
If for example, we had cutaways done of a 1959, 1964, 1966, 1971,1976, and 1985 models in factory paint schemes, we would have representations of all the major model changes.
Once those "template" versions are completed, it would be possible for an individual owner to arrange to have a customized drawing done of their airplane based on the model template, perhaps at a lower cost.
Very Cool.
