Hey, thanks for your reply. I've decided to put the project on hold for a bit. I received some plans for a foam 777 that I'm planing to build first, so that i can get some experience working with foam. After that, I plan on buying the plastic model, to use as reference, and to get some cross sections from. From there I will make a foam plug of the fuselage, from which I will make a fiberglass fuselage. I am hoping to be able to detail the interior. Though I imagine making 300 or so seats will get quite tedious.
