The fuselage comes pre-moulded too, of course, with a lot of surface details moulded in. However, the openings in the fuse (there are many) for exhausts and cooling air, etc., don't look as realistic if they are not "opened up." This was done on ths model for all openings into the fuse. The part of the moulding that covered the opening was removed with a Dremel and a file. Then a polyply piece was glued into the fuse on the inside to extend the "duct" back up into the fuse. On large openings, "sides" for the duct were also added on the inside of the fuse. This was all reinforced with a fiberglass tape strap over it on the inside and the gaps on the inside of the duct were filled with Bondo. The resulting duct was cleaned up with a file...

As you can see in the picture, the complete set of lights from Dan Gill was added to the airplane as well...
