I would dearly love to have a Little Bird variant: short skids, Batman black, external seats / weapon mounts, etc. :
The “real” Little Birds are based on the D airframe (round nose), but there’s a newer version designated AH-6i that’s based on the E.
For x-plane purposes, it’s almost purely cosmetic (the FLIR would be cool, but I could live without it), but it’s worth an expansion price a la the two versions of the 222.
