One of my favorite characters in The LEGO Movie is Will Arnett’s Batman. His Batwing is also rather awesome. Stefan Edlinger (Brickmasta) loved it so much he decided the Batwing deserved the real LEGO treatment.
Stefan spent several months amassing the parts and reverse-engineering the model from the movie (and accompanying video game). The process proved challenging, because as Stefan puts it “Clearly the mechanics and physics in the movie and the game are different, easier, lighter to make it possible for such great creations to exist.” He had to make the Batwing a lot sturdier than the construction briefly shown in the movie and video game.
