1:40 scale, based on the version seen in Revenge of the Sith.
Is able to land in the configuration seen in Revenge of the Sith and Battlefront 2 2017 by shifting the round 1x1 bar with handles against the rounded 1x2. Best way to do this is detaching the panel hubs from the build and reattaching in the preferred configuration.
I intentionally designed the build minimize out of production parts. Although pick a brick will most likely not have all the parts required, my goal was to avoid any out of production pieces to make it accessible as possible to build.
Instructions use a dark bluish gray 2x2 dome as a placeholder for any astromech head you may have.
