Greetings Stefan - I've checked the description of the file contained within the download. The copyright on the aircraft is 2002, placing it before the release date of FS9. The aircraft is made for use in CFS2. I had another look at the individual files within the texture folder. Re: the spinner - it shows as red with a white spiral from the hub to the rim - a "spiralschnauze." There are two prop files - one is "prop.bmp" and the other is "prop2.bmp." In the texture folder they show as circular grey shapes with three narrow darker grey triangular shapes within the circle. The whole of both is surrounded by an unbroken yellow band. When the sim aircraft is displayed in FS9, everything shows with very good detail with the exception of the spinner, prop blades and the annular radiator at the front of the engine - they do not show at all. Right now it resembles a jet engine intake with no exhaust. The spinner file has 256X256 pixel count, 300 dpi horizontal and vertical, and an 8-bit depth. "Prop.bmp" shows 256X256, 0 dpi and an 8-bit depth. Same for "prop2.bmp." Within the aircraft folder, there is an "IIT" file from 2002. What does this do? There is also a "Certify.BVD" file as well.
Later - surfed the site and noted Cees Donker asked a lot of questions about this very aircraft in 2010. A couple of sites were listed in the string, so I visited them, and downloaded the files mentioned. Interesting to note in both releases what is called a Ta-152H in the most recent release was described as a Ta-152C in both earlier releases. There was also a patch available. I've downloaded everything and installed the patch. Will start the sim and see if that made any difference. If not, it's time to try both downloads (one of which was uploaded to the web in 2007, well after FS9 was released) and see which of them works. You never know . . .
