Anyway, today's test involved their old Jaguar sets, Phantom sets and the two B-52 packs (G and H). I also tried the Galaxy, F-111, Blinder and Backfire - though I don't remember if those were originally FSX or FS9 models.
The good news is that they all work very well indeed. I just had to make the thumbnails and that was it. All hunky-dory. Okay, the Jaguar VC is not exactly top drawer - but it's good enough. I'm going to have lots of fun with FSX now!

Oh - and don't tell anyone, but I have FSX standard - which doesn't include some of the 'Gold' or deluxe edition aircraft but.. ssshhh... you can copy over the model folders from P3D and they all work then, in FSX.

So now I can use the Maule for my farmstripping

PS - I checked and it's definitely the FS9 Galaxy - quite a nice job, too
