I must agree wholeheartedly with you Tim.
I consider the CS aircraft range to be among the best that I have.
I too have no idea what the correct numbers are and I really don't care.
All my aircraft models fly to my satisfaction and as to the 727 being underpowered, I held my own in a race around the Lake District with some Boeing T 45s!
The level of detail in the textures and visual model is unsurpassed.
I also own a 61 year old Land Rover and that world is also inhabited by its fair share of "rivet counters".
Some of them really know their stuff but I fear that many do not and like so many "experts" to be found on other forums have gained their knowledge from either magazines (comics mostly) or what they heard in the pub.

Regards,
Nick.
