The original Dark Side Developer Kit set (9754) came with three different booklets (1, 2, 3) with instructions to build a Droid Starfighter, a Destroyer Droid (aka Droideka), and an AT-AT. Additionally, they had pictures of the alternative builds. Among these, you could find the Armored Assault Tank (or AAT for short).
I always liked this tank. I think it looked amazing, especially in Episode Iās Battle of Naboo. Thus, I was very excited to back-engineer the construction of this model. Fortunately, the booklet contained quite a few images, making the recreation a bit easier. I find the design of the build very interesting and clever: with only one motor, the AAT can move and make the turret look for a target.
Overall, I am very happy with the results. I wanted other people could enjoy building this model as much as I did. You can find the actual instructions for it here.
