Badly optimised sums 'it' and a few other CS models up perfectly. I have to remove AI at LHR to be able to gather enough FR's to takeoff in the 757! I agree.. their C130 is by far the best model they've produced thus far even though I only fly it once every full eclipse of the sun!
I own their 727 for FS9 and it's cr*p as it feels somehow playmobil.
But a decent 737-200 is something I'd really long for. And another reason that makes me think of switching over to FSX.
