I think a decal is possible, but I agree with Nosecone - it will be difficult. I have has success with a rudder decal for a J-6/MiG-19, only took about an hour of resizing and moving it around using the decal.ini.
Both the JASDF & Belgian skins are looking very good.
Nosecone, I thought you had some serials made up already, from a previous post?
Sony, did you paint paint your serials on or use a decal? I have found a good color pic of 'FX 26' in natural metal from 1964, a color drawing of 'FX 1' and a side & top view of the camo scheme for reference.
Am thinking about doing a couple Spanish AF skins, one in Anti-corrision grey, and a natural metal skin form Escadron 104.
We might want to combine efforts, in order to speed things up a bit, and add several more skins for download - let me know what you both think....
These RoCAF birds are overall light grey, with better shots of the wings.
