I suggest you finish the whole basic plane, before mapping it seriously (The fuselage and wings, including the stabs and other details, with all the doors, windows, gear wells and such cut). Then take a picture of left, right, top, bottom depending of the part you want to map, for example the fuselage you need just the left and right side. If you want more detail you can also take a pic at the flat bottom parts. Then just paste everything in a texture sheet and try to preserve space, or not if you have no trouble in using multiple texture sheets, but try to put stuff as close as possible with no big white spaces in between.
To map the fuselage just map the first side, it can be left or right. Then select the polys of the oposite side and, with those selected, add a uvw map modifier and make it square, then add a uvwunwrap modifier and place the polys on their correspondent space.
Ah, and take the pics in orthogonal views, not perspctive otherwise they won't fit the model when you try to map it.
