Trev, I find myself in the same boat, i.e. no time or facilities for scale building (all I can manage at present is an Ugly Stik ARF). So I too have decided to focus on "scale research" for the moment. Before I left the US I ordered the data files on the Albatros BI and II, CI and CIII, CV, CVII, DIII (OEF), Pfalz DIII and LVG CVI. While they are all informative, some are better than others. Some of the 3-views are better (more detailed) than others. None of them represent the sort of comprehensive documentation of a single aircraft that you see on the FTS EIII CD for example. But you'll get some new and interesting original photos (like the one of the Pfalz with a teddy bear wired on behind the cockpit) some color plates with documented color schemes, lots of textual description of features important to modellers, and enough close up photos to be able to model the major features (and variations). I don't imagine that any one all by itself would be sufficient though.

I also ordered some standard 3-views from Nexus in the UK (don't have their address handy at the moment) but those were a bit of a mixed bag. Most were little better than you can get on the web, but the one of the LVG VI was much larger scale and full of informative detail. The DIII was also OK.

One resource that I quite frankly treasure is the MAN Scale Drawings WWI book. This is a collection of drawings most by William Wylam and Joseph Nieto and while many of these drawings have come under attack for assorted inaccuracies, I still find them the most exhaustively detailed available. For example, the several pages of technical drawings in this book on the Pfalz DIII totally blow away the simple 3-views in the Pfalz DIII Windsock datafile. And I can't imagine how anyone building a scale DrI or DVII could even consider going forward without the Joself Nieto plans (in the case of the DVII four large sheets of them) available fairly inexpensively through the National Aeronautics and Space Museum.

I guess all I can do for the time being is dream and read -- and work on my flying skills a bit. BTW, I'm currently 3 for 4 crashes to flights on my Spacewalker ARF! But I'm gettin' better!
