Looks like the mapping for the T4 & T8 are pretty much the same, so you'll probably be best off using the T4 paint kit as it's got the camo on it already
I've had a quick look at this and I thought the S-55 map was a mare!
I dunno how you're gonna get any text on it. I had to reduce FLIGHT SYSTEMS to 1.5pt (no typo) to get it to look vaguely representative on the map and BEDFORD is smaller still. Needless to say, it doesn't display correctly in-sim
The gaffers models aren't bad on frames and with only one Harrier (I hope only one) running at Bedford.. it's not gonna make a whole lot of difference in the grand scale of things.
Ben.. it's not that the text is unreadable.. that I could handle. It's breaking up and looks horrible. A workaround may be to double the size of the map.. put the text on then reduce it again in the hope it holds The HS logo and RAE badge are likewise gonna be no more than dots
Rgr your last on the UKMIL models. Did they not do an FSX version
