Thank you guys!
As far as know, nobody produces white slovak markings, so I had to do them myself: the decals (national insignia, tail numbers, warning signs and the Mil 17 logo on the frontal armour plates) were all drawn on Corel Draw and printed with an Alps printer.
The camouflage too was made with decals; after I painted the light green base color, the pixels were cut from a clear decal film, painted with the three colours of the camo pattern (red brown, sand and dark green).
The flare launchers were scratch built...
Bye!
