Wilhelm, I have finished the fuselage portion of this thing. I will not work on it any more for now because I dread to see what other glaring mistakes were made in the developement of the other parts. If I decide to continue I will start another thread instead of using your thread.
I put it together starting from the front and working aft. The first alteration to make the sections fit carried on to the back. You make a correction on some parts then you have to make corrections on the following sections of the fuselage so it will go together.
Good luck in your endeavour.
