No one else has given you an answer yet so I'll just provide some info. I've been doing this in the reverse (importing CFS2/FS2002 planes into CFS1), which means I have to redo/add some files. I may not be a lot of help here, except that I remember that I could import CFS1 planes into CFS2 (still have the Discs but I haven't had it installed since two computers ago).
Inside each standard CFS1 aircraft's folder (whereas *** is the name of that plane's aircraft folder) is a:
model folder,
panel folder,
sound folder,
texture folder,
aircraft.cfg file,
***.air file,
***.cdp file,
***.dp file,
***_check.cfg file (if included, this must be refered to in the aircraft.cfg file, after checklist =).

panel folder:
Are all of the bitmaps (the .bmp pictures for the views within the cockpit) there?
Does the panel.cfg have the proper entries, named according to the accompanying .bmp(s)?
*See note below.

***.air file:
I would doubt that your ***.air file is corrupt since your plane is there but there is an entry in some of these giving the name of the normal panel file (this isn't accessible with a normal text editor); someone else would have to tell you whether or not this effects CFS2.

*It is also possible in CFS1 (and probably CFS2) to click a panel "on" or "off". This is normally done by tapping "Alt" on the keyboard, clicking down "Options" and clicking the entry for that "window" (panel view). It is also possible to do this with a left click on the screen, then clicking the entry to check or uncheck (on or off) the window view. Sometimes, inside the panel.cfg, is a "visible" entry; if there's a 0 following the = then that window (panel) won't be shown at game start; with a 1 it will be. Also, if a panel was turned off during last play then it may not be displayed with the next start.
Oh, well, I may have only provided a lot of useless information  .

I do not find any reason for importing planes from CFS1 to CFS2. They are both find simulator but in converting planes from CFS1 to CFS2 you will find the CFS1 planes wanting and less than complete.

I did the same thing at the begining and after a while I deleted the CFS1 planes from the CFS2 Sim. They just did look as good in CFS2.

You got hundreds of planes for CFS2 right here in this same Simviation Website in the CFS2 planes section. Check them out.

As for H. I wonder why you dislike CFS2 so much?

I guess you really do not care for the  the Pacific Theater at all. Thats really a shame. But as they say to each its own.

Remember CFS1 and CFS2 are fine games but they both have  different places in the Sim world.

Enjoy them both. I know I do

I began my response to Hagar before you made and entered yours (this will take some time -- piecemeal -- while I do other things). Neither would I say I "dislike" CFS2. When I was 10 years old I started my own little camp, Hurklez, with its own flag. When other camps were added, I began writing short stories, embellishing (greatly) our exploits against one another. By the time I was 12, we'd grown to well more than a dozen camps, split into 3 leagues, each with their own flag and a color scheme for each (a color for the league they were of and 1 to 3 for the individual camp; more camps were added even though we already had more camps than people). This bled over into my plastic models of WW2 1/48th scale planes. Therefore, by the time I got CFS2, I didn't like it as well because I was already repainting CFS1 WW2 aircraft according to my own schemes even though I found I was able to work with CFS2 textures, too.
A few strides in the bitmapping were made between CFS1 and CFS2 and from CFS2 on. The only, and best, way I could originally compensate was to rework each texture pixel by pixel; a lot of time and still very limited when working with an original 256color format (using 24bit and reverting to 256color in MsPaint will often provide an unwanted effect in the color changes). Still, it provided for some better texturing, especially of limited color 3rd party downloads. I then got a scanner and found making and transfering hand made panels (as long as I made sure the top left 2 verticle pixels were true black) and textures provided much better results.
A few weeks ago, I did some retexture work in 24bit and, just to try it, utilized my recently obtained Paint Pro 8 program to revert it to 256color. What a difference -- beats MsPaint reversion all to pieces! Of course, this is with my WW1 rework which, unlike my WW2 world, has been kept closer to actual historical schemes. I've finally made contact with some of the designers (so I can upload my "Ye Royal Shaft" F.1 Camel and Dr-1 repaints; if anyone can provide a legitimate address, I'd much appreciate contacting Curt Reimer in reference to my Albatros repaints -- otherwise I'll have to have an alternative .mdl for those, as well, tweaking everything else, which is very time consuming).
Therefore, James, should you upload my CFS1 repaints into CFS2, I doubt you'll find them quite as "wanting" as some of the 3rd party uploads specifically made for it. A real good "from scratch" texturing takes a lot of time and there are those out there that well outdo me; I'm not really that patient but, still, I've put some time in. Understand? 8)
