Both, both, both please... pretty please... uncle
I have been well satisfied by Sibwings model quality so far. Despite my moanings about her looks, I have wanted the Safir since the FS9 version was announced - but FSX was on by PC just days later.
The only caveat I have is seeing developers advertise "FULLY FSX COMPATIBLE". That one word "Fully". How often do developers misuse that word (I was going to say lie), By dictionary and legal definition, there aren't many who use that word correctly. I have around 130 or 140 different airtcraft folders on my PC. Dozens of freeware and several payware. I can think of only three payware developers who actually do use and mean the word "Fully"
Realair Sim, Nemeth and Iris as developers
Aerosoft as publishing house - and then not all their X products are "Fully". I think I have more freeware models that "comply". I am very repidly getting P'd off by that simple word. It wastes my money as a painter.
Specular textures are a function of FSX - if these aren't there as separate paint sheets, then "Fully" is not applicable. There are often a few other things still missing on top of that, but I am not going to tell the developers to go read the manual

Still, from my readings so far, there are SDK things that still aren't being applied in "fully fsx compatible aircraft".
And Andrey - I am not singling you out - I am like this with all the other devs too, whose products I add to my hangar. For me, it's better for me to be a PITA if it helps others in the long run, so I am less worried what people think about me personally, all I want is the best sim for everyone.
By the way - the Safir is an excellent plane. I really do enjoy flying her. But painting?
