I appreciate you making yourself this much work, and so far this is good writing, as well as a good compellation of images.
However I absolutely hate FASA's idea to put transwarp into the Excelsior class, which is for me just plain stupidity and ignorance of canon. Which is why FASA is non-canon, anyway :P
Will you ever be planning to do a canon Excelsior Tech Manual?
Did you not see ST-III?
FASA didn't come up with the idea that the Excelsior was built with transwarp drive. The people who made "ST-III" did. It was a major bit in the film. Go back and rewatch it... (Styles' comments are priceless.)
