Here’s a look at Book 4. Some of the diagrams I do are completed in just a few hours. Some take considerably longer… several to many man-days, sometimes spread out over months as I dial in details. This one was sort of mid-range. The most complex and time consuming are typically the diagrams of aircraft that were actually built… those have to be accurate, and more details are available. This one is of an unbuilt aircraft that is reasonably well documented, but was a configuration that was in a constant state of design flux.
