Here's all of the Boeings that I've redone at the request of another member. Not all of them, but quite a few of them had to be redone. Most of the fixes were trivial, but the 767 and 777 had to be reprofiled. If you think you can do a better job at reprofiling the 767 and 777,
don't - I can tell you that whatever instinct or eye you have is, to put it bluntly, flat-out wrong and we will end up at this mess again. Or at least provide good justification and I will look up the evidence for/against it.
Also, be wary of using the 737NGs (700 and 800) - their lengths might not be correct. The 737-500 is most certainly too long and I just realized I forgot to fix it - instead remove the winglets from the 737-600 to have a 500.
EDIT: Actually I will need to reprofile all of the tails of the 737NGs to be accurate.
EDIT #2: Disregard that first edit, I just discovered that the differences between the tails at Shipbucket scale are invisible anyway.
The 747SP is the best I can do with the original drawing without making it too wonky, but it will need to be completely redrawn from scratch. Anybody is free to take a try at it.
The red markings and other things are scale guides. Either ignore them or use them if you want to redraw some of them (particularly the 747SP)
