The April competition required the creation of a MOC from a single set. There were 21 approved entries. The three judges scored every entry with their own criteria and weightings which included creativity, originiality, playability, instructions, and a host of other aspects.

The combined scores revealed the winner as MOC-1466 Shadow Wing by Alanyuppie who will receive a gift certificate from their choice of either Amazon, eBay or shop.lego.com for the equivalent of US$100 in their currency of choice. Congratulations!

Judge's Comments

Nathanaël Kuipers - "From my own experience I know how difficult it is to design and build a transformer in bricks, especially when there's no reference to use. Both structure integrity and the looks in different modes are extremely challenging, and that's without considering using parts from just one set. This entry has it all; both modes look good, the structure is fine, the transformation is cool, the instructions are clear, and to top it off, every part was used."

Jason Allemann - "I was very impressed with the originality of this entry. Building a transforming jet from a cat and a mouse showed some incredible creativity. The ability to transform and obvious swoosh-ability also gave it high marks from me for play-ability. To top it off the clear and easy to follow instructions mean that many other builders can enjoy this great alternate model."

Attila (plastic.ati) - "I was very satisfied with the careful process of chosing the right elements for the right parts of the final model, the efforts to make it tasteful in both forms, and of course, it was great to see, how some furry animals changed their body to a really transforming robot/jet. The sturdiness of the model is far over average, which is essential for a transforming body, and it is even poseable, which (again) increases the playability. The clear color scheme is also a good point, as well as the easy-to-follow, organized instructions."

A big thank you to the three judges who volunteered their time for this competition, not to mention foregoing the ability to enter it themselves!

There were a few other entries shown below that came close to the winning entry and deserve a mention!

    I killed my furry cat last week to build this shadow wing and it is a very sophisticated build. Transformation is a little bit hard to find out the first time. It is really sturdy taking into account the creeping-and-crawling technics used with the limited amount of parts. I wouldn't have built this (I'm not that fond of mechs) but this judgment persuaded me.
    And this proves instructions from photo's can be very good!

    I should say thank you to the judges as well, I forgot to do so in my other comments! It is probably a good bit of work to look at all these creations carefully.

    Thanks guys!! :D

    but one thing I need to clarify though. Not all parts from the set were used for this MOC (there's about 20 pieces leftover I think). This is one of my 2 submitted entries in this site and I simply imported all parts from that set for this competition (assuming since the competition is about building from one single set, precise part count is not required.)

    Anyway.. thanks to the judges for such flattering reviews. Me too, is curious to know the details and scoring on all the entries as well.

      Precise part count would have been good since proportion of parts used was one of the judging criteria. Congratulations on your win.

        Agree. It would be crazy to check every entry for part count, so it should be essential to say the truth when one submits a MOC.

        (The part usage was still high enough even with those 20 or so leftover pieces, so my points haven't changed because of this. These points went from 0 to 5% of total, depending on the usage%-interval in my system)
