The HGUC 1/144 Xi Gundam recreates the massive Minovsky-Flight machine piloted by Hathaway Noa in Mobile Suit Gundam: Hathaway. Released by BANDAI SPIRITS on April 24, 2021 for 6,600 yen (tax incl.), its biggest draw is a presence that hardly feels like 1/144 scale. The Minovsky Flight wings deploy by hand. Build difficulty sits at three out of five, with an assembly time of around four hours. This review shares hands-on impressions from a straight build—size, articulation, color separation, and that tricky self-standing balance.
1. Introduction ― About the Xi Gundam
The Xi (Ksi) Gundam appears in Mobile Suit Gundam: Hathaway as the Minovsky-Flight machine flown by Hathaway Noa. Its standout feature is sustained flight within the atmosphere, and on screen the sight of that huge white frame soaring through the sky leaves a lasting impression.
After watching the film, I couldn’t shake the image of that large white machine cutting across the sky, so I picked up the kit shortly after release. Here I’ll share honest impressions from actually building the HGUC 1/144 Xi Gundam—its scale, ease of assembly, and finish.
For an HG kit this is a hefty package, and opening the box revealed a runner count that genuinely made me brace myself.

3. Package & Kit Contents
The box is large for an HG, and you can feel the density of the contents just by lifting it. Inside you’ll find:
- Colored runners: multiple sheets (white, blue, red, yellow, gray)
- Polycap runner: 1 (PC-002)
- Foil sticker sheet: 1 (for sensors and a few accents)
- Instruction manual: 1 booklet (color recipe and mecha notes)
The base white/blue/yellow scheme is covered by molded colors alone, with the foil stickers serving mainly to fill in sensors. The manual also includes background notes, so you can follow the lore as you build.

4. Assembly ― Difficulty 3/5, Around 4 Hours
Build difficulty rates three out of five, with roughly four hours of assembly time. No single step is especially tough, but the sheer part count stacks up into a long total. Here are the points worth watching, based on my own build:
- The moment I opened the box, the runner count—unusual for an HG—made me brace myself. Knowing the overall volume up front makes the build feel less daunting.
- With many large parts, take your time on gate cleanup. Rushing the cuts can mar the surface or leave visible marks.
- The finished model carries real weight, and getting it to self-stand required adjusting the leg angles. Trying to stand it straight off the bench, it tips forward easily, so plan that final tweak in.
- For flight poses, an action base or similar stand is essentially required. The more you use the deployed wings, the harder self-standing gets, so decide your display method before you start.
If you only have short windows to build, splitting the work into sub-assemblies makes for natural stopping points.

5. Out-of-Box Review ― Looks / Articulation / Color / Gimmick
The first thing that struck me after a straight build was a sense of bulk that hardly feels like an HG. Set beside my same-scale HGUC Nu Gundam, the Xi looked clearly larger—a full size step up.
**Design & proportions**: Compared against the film’s lineart, I noticed no major discrepancies. The overall lines are thick and the silhouette reads as heavy and solid.
**Articulation**: For such a large machine, the knees and waist offer a decent range. That said, posing it dynamically while self-standing brings on a forward lean, so a stand becomes the practical choice.
**Color separation**: The white base with blue and yellow accents is reproduced almost entirely through molded colors. I judged that a few stickers on the sensors were enough and left it as a straight build.
**Gimmick**: The Minovsky Flight wings deploy by hand. Mounted on an action base in a flight pose, it came remarkably close to the on-screen image, and being able to swap between standing and flying poses on a whim is a real plus.

6. Place Within the Series ― Comparisons
Within the HGUC line, this kit sits near the top for size and part volume. Lined up against my HGUC Nu Gundam, the Xi stood a full size step larger and, on the shelf, looked more than a head taller. Even against other Hathaway-related kits or standard HGUCs in the same price range, its part count and finished presence clearly come out ahead.
The trade-off is build time, which runs longer than a typical HGUC. This is a kit for those who value the satisfaction of the build and the display impact over quick convenience.

7. Quick Tips for a Cleaner Finish
As general recommendations, here are a few finishing ideas.
- Gate cleanup: With so many large parts, a two-stage cut followed by sanding keeps the white cut faces from standing out.
- Panel lining: The machine has many bold lines, so panel lining tightens the molding and plays up the bulk.
- Sticker handling: Some foil stickers straddle curves and steps; if you want a pristine look, paint those areas instead for longer-lasting results.
- Top coat: A flat top coat at the end tames the sheen of the molded plastic and gives a calmer, lineart-like finish.

8. Things to Check Before Buying
- Availability: Reprints come around regularly, so with good timing you can grab it at retail price. It has gone scarce when the film returned to the spotlight, though.
- Secondhand market: Stocked on Amazon, Rakuten, Yodobashi, Suruga-ya, Yahoo Auctions, Mercari and more. Prices vary depending on whether a reprint just dropped and whether the kit is unbuilt.
- Display space: The finished model is large and heavy, so prepare shelf space and a stand in advance.
- Build time: Around four hours, so it suits weekends or days when you can set aside a solid block of time.

9. Good & More
**[Good]**
- The runner count is obvious the moment you open the box, and the finished size feels far beyond 1/144 for high satisfaction.
- The hand-deployed Minovsky Flight wings let you switch between flight and standing poses on a whim.
- Molded colors alone reproduce the white, blue, and yellow well, landing close to the film’s scheme without paint.
**[More (points of concern)]**
- The high runner count means longer build time than a standard HGUC. If you’re newer to building, splitting the work into stages helps.
- Some foil stickers straddle curves and steps, and I ended up re-applying a few. Painting those spots is worth considering.
- Self-standing requires leg-angle adjustment and the model tips forward easily. Plan your display pose around a stand.

10. Score
Overall: ★★★★☆
In a word: “Strong build feel and real presence—display it on a stand and the satisfaction jumps.”

11. Conclusion
That wraps up the HGUC 1/144 Xi Gundam review. What stayed with me most was the moment I set the finished model onto an action base. On the HGUC shelf it stood clearly more than a head taller than the others, driving home just how large the Xi Gundam really is.
On the flip side, the part count runs higher than standard HGUCs in the same price bracket, and there was a point where my hands paused mid-build. For those who can carve out a solid weekend block, or for fans of Hathaway who simply want it on display, I can recommend this kit wholeheartedly. If you’d rather knock out a quick build, or you’re tackling your first HG, a kit with fewer steps might be the better starting point.
