I started this kit this summer then took a break. I'll get back to it real soon, as I'd like to get it done before my wife gives birth. There was a better thread, though it seems to have become too old and disappeared.
Millennium Falcon--Sci Fi at Z-5??? - Zone-Five Aircraft Modeling Forums
This is some great detailing. I have been playing around with the thought (and a little bit of work) of restoring this to the original Millennium Falcon from the Original Star Wars Movie. I much prefer it over the ESB modifications, although I do have a Fine Molds 1/72 kit.
I have the "falcon kits" sidewalls, but they are not really accurate to the five footer, so I am scratching new sidewalls based on the height of the "falcon kits" parts. I actually have an in scale Mazda transmission for the sidewalls for this kit.
Other than correcting for the curvature and the cockpit and cockpit tube, I am also effectively razing the entire back engine deck, and will build it out as closely as possible to the five footer.
I have also noticed on some pictures scaled from the five footer to 18 inches (ERTL scale) that the access bays ("holes" in the top and bottom mandibles) are slightly larger on the ERTL than the studio model, so I will probably visit this to see how much of a difference this makes and if it is worth the effort of correcting, as the discrepancy is very slight.
*hint, If you cast, the Fine Molds Falcon and Y-wing kits can provide some great in scale accurate donor parts. There are also other parts on the model itself, including the sidewalls, that can be cast and repurposed in other or more accurate locations on the model, including "Aurora" parts on the engine deck, which are facing the wrong direction, and little military 5 gallon "gas cans", of which more are required throughout the model.
I've done tons of research using pictures (readily available on the web) of the five footer, it's just finding the time to make it all happen.
