That's been a problem since that plane came out. Unfortunately, the dev that made the .mdl file for the plane is no longer available for permission to change the file. If he were still around, the .mdl file could be changed to accommodate the missing textures.
There've been a lot of people try to fix the blue situation, but to the best of my knowledge, no one has ever found a solution. If someone managed to use MCX to decompile it and fix the problem, without permission from the original author, there's no publishing it for others to use.
So, the blue remains, and always will, unless the original dev manages to make a return.
Since I've heard from "reliable sources" that he may have passed on, it's unlikely that he'll be granting any permissions in the near future
Does this help at all? Not super useful, I realized, and I'm sorry. Best I can offer, though.
Have fun, if you can take the blue problem in stride

PS: As to a manual. Did you look in the plane's \Extras\Documentation folder? Yes, the manual in it is for an older version plane, but most of the information is still fairly useful. Not ALL of it, and many things have been changed, but those things can be found in the thread. It's kind of a round-about way to find the information you're looking for, but better than nothing.
Jimi and Orion are working on a new manual for the latest versions, but since there's more, newer ones, coming out soon, it's one of those projects on a back-burner. The plane is getting new versions so rapidly, that any manual they were to write would be out-of-date as soon as they publish it.

As per usual the camera was in the basement.
