I some how missed this post. I'm not sure what level of construction your looking for,but I tell you how I handled mine.
Because of the double hull design you will have to strategically plan your painting/detailng sequence. Construct the upper and lower hull,the "head"or forward section, the rear pylon,and the nacelles. Take each of the 6 sub-assmblies and construct the model using masking tape to hold the completed model together. When you fell the alignment is to your liking, glue the forward section to the top hull. Then attatch the rear pylon to the lower hull.
Now remove the tape and you're left with 4 sub-assemlies which should not be glued together - the upper hull and head, the lower hull and rear pylon,and the two nacellels.
Paint ,detail,and weather the interior portions of each hull.
Now complete the construction of the model. the parts of the model that would now be extremely difficult to detail- due to the limited space available between the hulls- are now already painted. Now you have only to mask the pre-painted interior to prevent overspray and such that might occur while finishing the outer hulls. Any painted areas that may have been affected during the final construction should be easily accessible and can be refinished.
The many panels make it very easy to touch up painting and detailing as each panel can be masked and painted separtely, and in theory no two panels are the same anyway.
