Yes, since downloading this one I have becoem rather interested in it and started reading up. Seems the "M" variant first flew around 1982 and includes much newer high bypass turbofans (hence the larger nacelle diameter), with all the usual benefits. I think it also has upgraded avionics and systems.
John,
Downloaded and installeded the beta, and all I can say is "wow". This has got to be one of the best aircraft I have installed right now. On account of the panel not being finished yet, I have been able to fly it too
