As I have so far been building my Europa in a loft area, and have managed to get the, wings, Control surface and Cockpit Module completed in there. I am now unable to get the Fuselage Thought the window as I did with the wings etc. I decided the best and cheapest way was to use a shipping container for my workshop. This has been easy to insulate, and has made an ideal workshop with a good level floor. It is a length of 25ft giving me plenty of room with Secure Storage.
