An early review of the upcoming Red Five X-Wing Starfighter (No. 10240) has a lot of nice things to say. This UCS X-Wing is the most detailed and well built version yet. A huge leap forward from the original UCS X-Wing (7191). Everything that was wrong with the original has been fixed, especially the delicate wings. The only downside is the slightly small R2D2.
This set is destined to become one of those fabled Lego sets. Right up there with the original, cafe corner, and green grocer, in terms of the resale market. A set like this will always be in demand.
