Dan,
I often (to copyright dismay, I expect) digitally photograph pages of interest from such manuals, when I cannot take them away to copy them otherwise. A good digital photograph will be darn near as good as a photocopy, and with a bit of cunning, can be scanned, "OCR'd" and turned into a text document if need be. With a bit of hunting, you might also find a genuine factory training flight manual for the model of aircraft of interest. It will be as effective as the real one for this purpose.
Although as Pistons suggests in this case, substitution from another model would mostly work, this is generally not a great idea, there are subtle changes sometimes. I do buy manuals off ebay from time to time.
