I bought it right after its release, but I was intimidated by the need to paint the two pilots and the large number of track parts, so it sat in my stash for a while before I finally decided to build it. (This was several years ago, though 😅)
I only filled in some of the molded details on the shoulders and barrel; it's mostly a straight build.
I focused on the painting, but I left too much of the base gray showing through, making it look rather gaudy. (This always happens when I do gradient painting 😓)
It has quite a presence once completed and I really like it, but the downside is that the track parts are fragile and I can't handle them carelessly.
