Biggest thing I notice is the window and door placement as well as a slightly different slope towards the back of the hump. The windows appear a bit oversize too. Personally my only issue with the plane is that I can't seem to fly it above 10 FPS. I do agree with those who think the criticism is undeserved, though. It is an astounding effort, and to compare it to the FSX default 747 is lunacy. Tongue FIRMLY planted in cheek, I would also like to bring up the troubling fact that the spacing of the rivets is COMPLETELY off, it should conform to PUBLISHED stringer locations and represents a CLEARLY UNACCEPTABLE flaw in the shoddy external model. I also noticed that the blade antennas are disgustingly wrong, off by a complete 10 degrees. Honestly, it's THIS kind of thing that makes or breaks a great sim. If Laminar can't get their act together, all of their work on flight model, ATC, atmospheric effects, autogen weather, and other things secondary to the external models of the default planes will be completely wasted, as NOBODY will accept anything short of perfection when it comes to default aircraft, especially one which is flown on a regular basis in real life by SO MANY simmers. Oh wait...
