Is this real life?
Just dont try and do it all in one peice, thats the mistake I often make.
Do the engines with a cylindrical map, and dont be afriad to break other bits down so that you can apply a planar map to each surface.
Sometimes a cylindrical map can work for the fusulague too, and if you are absolutly sure you have finished the modelling, try UVunwrap.
Ah, maybe that's my problem then. I look at texture maps other people have made and they're always one single piece, so that's what I've tried to do. I just end up with a mess. I might have another go with your suggestions when I've modeled some more of my Mk VII.
