What a beautiful set! I missed the first UCS Y-WING many years ago and it was the one I was most gutted about.. however this more than makes up for it and the newer techniques and pieces that are now in the Lego designers arsenal add a major touch of better detail that makes this model truly stand out.. as for Greebling this has more than I've seen on any official set, seriously! This thing is smothered in small details that are accurate to the source material.. even on the bottom of the craft! all the cooling pipes and engine details and pumps etc are all here and they look absolutely fantastic! Another nice touch is the folding landing skidgears that fold away neatly against the fuselage.. and as for the construction of the engines they are brilliantly put together and remarkably sturdy The designers truly have gone to town on this and it shows. A couple of small niggles of mine are the inclusion of stickers but they have been in UCS Sets for a while now so that's nothing major.. but the biggest niggle is the lack of armprint on the minifigure.. I mean for a £170 set I would at least like to see some exclusive printing Lego! On the whole though this set truly is a work of art and a worthy addition to any UCS Collection. Another Excellent job Lego
