Over many months I have been transitioning to FSX, finally deleted FS9 from my HD. However, I'm mostly still bushflying... my current rig doesn't like cities or heavy AI, so I am, for the most part enjoying Orbx's Australia and PNW regions. Really great.
One thing I really loved about FS9 though was the diversity of aircraft, in particular the British classics. Frankly, I could never go back to FS9 now, it's just...not nice...after months in FSX. I know Just Flight are doing the Comet and we have good Spits and Hurricanes about now. I miss the HS748's, the BAC1-11, Tridents, Chipmunks, Provosts etc. I was at the De Havilland Museum again last weekend and wished that the Dove and Heron and especially the HS125 could be replicated for FSX with a high quality VC. I'm sure i saw something about the HS125/Dominie some time back, can't remember where.... I'm guessing this is the best plce to ask.
Cheers
