Since this section seems to cover CFS1, 2 and 3, which specific fs?
It also seems, since the download sections CFS link, FS link cover all of the MSFS genre, you don't like any of the add-ons, either?
In the case of CFS1, most all of a default plane is included in one or two 256-color bitmaps; somewhat limits texturing but I managed and a better graphics program assists a bit.
