This is a tough and accurate representation of Han Solo's iconic ship and a vast improvement on the previous `mid-size' model. It is though, like most lego models of this size, very much for display purposes rather than for play.
Building time is probably around 3 to 4 solid hours and poses a decent challenge to construct, with 1254 pieces in total. On building, I was struck (as I often am with lego) by the cleverness of the design. The roof of the falcon is constructed in 13 hinged segments that can be turned upwards so the interior of the ship is completely exposed. There are not many gadgets, but the detail inside the ship is excellent, including the chess board seen in Star Wars and the smuggler's compartment. The circular body of the falcon is constructed using a number of small hinged pieces that lock together very neatly and tightly, keeping everything together. Others have complained that the underside of the ship is a little uninspiring to look at, but I believe it has been designed with strength in mind and certainly seems to do the job.
There are 6 good minifigures included, though you may find them duplicated with other sets you own; Han Solo, Princess Leia, Luke Skywalker, Chewbacca, Obi Wan Kenobi and Darth Vader. Vader may seems a little out of place in the set, but is no doubt there for his lightsabre duel with Obi-Wan at the end of A New Hope. Perhaps the inclusion of figures of R2D2 and C3PO would have also been appropriate.
Cost-wise, I have seen the set available anywhere between £95 and £130, so it is probably best to hunt around before purchasing. Beware that the dimensions in Amazon's listing above are the dimensions of the box in which it comes, not of the completed model. The completed ship is however quite large and heavy, weighing in at around 2 kg and it actually measures about 46cm in length and 33cm in width. In lego terms it represents pretty good value in comparison to some of the other sets available, and a good investment. In any case, the completed Falcon looks absolutely terrific and is surely an essential purchase for any collector of Star Wars lego.
Definitely the fastest hunk of junk in the galaxy.
