Piotrek1, yes, of course its possible to do a "slot".
When I said "good luck" with it than I did this for another reason:
imho its not enough to just have a icon, emblem. etc.
And so for the work to find out more info: I wish good luck
as it seems hard to find good info on the net in some cases.
I found not only one photography showing a Heimwehr plane.
All we have is this pic I found and linked. So we do not know:
What kind of emblems did they have on the wings. Were there any?
Whats about the numbering? Were there any other planes apart from
what I mentioned above? Where were their homebases? Who exactly
operated them? Whats about the ranks in this Flying corps?
Do we know any pilots? And so on...
There is a lot of research to do and I fear its not possible without
buying books (when there are some available at all). Contact some
historians here in Austria. Etc.
So when someone wants to make a campaign with all whistles and bells,
means: emblems/icons, hymn, ranks, flag and put all this in a new
campaign folder slot (blue? red?), then there really is a lot of work to do.
and for this I wish him/her good luck. I am not so much interested in this.
When I did the search for this Heimwehr Corps I came across other
missing forgotten countries and in this case: a forgotten airwar!
The "Carinthian Air War" as part of the "Carinthian Border War" 1918/1919...
Just a few pics links:

I did a search using german language only, but there should be some
search in slovenian, crotiatia, serbs language too.
So I found infos about the border war, but nothing essential about the air war ..
were there any dog fights, ground attacks, losses or was there reconn only?
Number of planes involved? Wich planes exactly?
etc etc ... I found nothing ..
So when a mission maker wants to tackle this and maybe wants to make this
a complete pack with campaign folders with flags, hymns, ranks, insignias etc ..
good luck with finding out all about this war.
