First and foremost, congratulations to DanCodd for reaching 10,000 supporters on LEGO Ideas, and toward everyone for all of the support of the Rolls-Royce UltraFan® - The Ultimate Jet Engine project! The results of the LEGO Review are in and you can see full details on the LEGO Ideas Blog.

Review Results for Rolls-Royce UltraFan® - The Ultimate Jet Engine

Our team has thoroughly considered the possibility of releasing this project as a LEGO set according to the criteria of the LEGO Review. Unfortunately the LEGO Review Board has decided that we will not produce this project as a set.

Thank you to DanCodd for the passion and creativity that went into this project, and to all of you who voted so that we would have the opportunity to consider this as a potential LEGO set. We’re sorry to deliver this disappointing news.

How do we arrive at our decisions?

By gaining 10,000 supporters, a fan-submitted project moves from the Idea Stage to the Review Stage, where it earns the opportunity to be considered as a future LEGO® set in a process called the “LEGO Review.” Gaining 10,000 Supporters is just the first step in this process.

A "LEGO Review Board" composed of professional set designers, product managers, marketing representatives, and other key team members examine each qualified project. They build concept models and determine if the concept meets our high standards for what it takes to be a LEGO product; including factors such as playability, safety, and fit with the LEGO brand. Every potential LEGO product, including those developed internally, goes through a similar process and must meet the same standards.

The amount of time this takes varies due to all the factors involved. Unfortunately, this process sometimes means that well-conceived projects that gain just-as-passionate followings have to be turned down. Please note that the LEGO Review Board makes all final decisions on which new sets the LEGO Group will release based on LEGO Ideas projects.
