Just let me affix my "Picker of Nits" star badge... Okay there we go.
The OD anti glare on the engines should start at the top center (12 oclock looking at the radial face) and arc down 1/3 the side of the cowling, stopping at either 4 oclock or 8 oclock depending on which side of the aircraft it's on.
Default had it start at 11 oclock and go to 3, or start at 9 and go to 1 (depending on the side) which isn't exactly accurate.
Like I said, it's a nit. Consider it picked.
*takes off the badge, puts it away*
EDIT: I'm not entirely sure if the outer engines had OD, either. I left them on, on mine. I know at least one model kit a LOOOONG time ago that said to only paint the inner engines like that. Of course, it was of pathetic quality, and possibly was a poor source of info.
