This article is Part 2 of an ongoing series. Read about the LEGO Grumman E-1 Tracer Part 1 here.
About two weeks ago, I started building a new aircraft model: a Grumman E-1 Tracer. Because some of you might like to know how one might build such a LEGO scale model, I am documenting my process in a short series. In the first part I described why I decided to build such an oddball aircraft in the first place and how I plan a build like this. I also explained that I usually start by building the difficult bits. A few of those are the subject of this article.
The Tracer’s wings are not quite perpendicular to the fuselage. This wouldn’t be much of an issue if the engine pods and the main undercarriage weren’t attached to them. I have built angled wings before, including some rather large ones. In practice, however, it is almost impossible to mount the wings using hinges and also have them carry much of the model’s weight. Furthermore, if I were to build the wings at some weird angle, I would then have to figure out how to align the engines attached to still be parallel with the fuselage. My solution is to attach both engines directly to each other and also to the fuselage using a bridge structure. I built this bridge perpendicular to the fuselage using plates. I then put the actual wings on top of it. By combining 2×3 and 2×4 wedge plates I filled in the gaps where the tops of the engines join the wing. Getting everything to fit nicely involved a lot of trial-and-error, but it works.
