Paints for a lot of Diamond/HOAC DA-20/DV-20 Katanas - 104 to be precise. Painted as DXT1 for FS2004. Most of these are still in operation with the same organisation, some may have moved on, in some cases into private hands. The Spanish one crashed last year! My FS2004 AI system is frozen in 2019, and it was flying back then. So, use or discard at your discretion.
The aircraft CFG file will need to be renumbered (FSRenum or other programs can do this for you).
As far as I can tell, the only Katanas made by Andras Neuman came with "boots", or spats as I prefer. Most of the aircraft painted have had these removed and fly with bare wheels.
