Bandai 1/144 HGUC RX-105 XI Gundam

Mafty's flagship, big enough to make the Federation take notice

The RX-105 Xi Gundam is Hathaway Noa's personal mobile suit in Mobile Suit Gundam: Hathaway's Flash, a large-scale, Minovsky-flight-capable Gundam built for Mafty's anti-Federation insurgency. It's the direct counterpart to the Federation's RX-104FF Penelope, and at this scale it carries the same commanding shelf presence as its rival. Released alongside the Penelope as part of Bandai's 40th anniversary Gunpla celebration, this is the kit that completes the central conflict of Hathaway's Flash at 1/144 scale.

The Xi Gundam transforms between mobile suit form and flight form, with the Minovsky flight unit's wings and leg blades reconfiguring for atmospheric combat. The shield attaches by displacing the arm's hexagonal parts, and robust joint components throughout the build deliver stable posing in both configurations.

Build difficulty

This kit is best suited to intermediate builders comfortable with larger, more complex HGUC builds. Genuine builder feedback describes the process as stress-free with a big, imposing result, though a couple of reviewers note it feels closer to a Master Grade than a typical High Grade once you're holding the finished piece. The transformation mechanism and part count make it a more involved build than a standard HG kit, but the snap-fit system keeps it accessible without glue. One tip from a professional review: thickening the arm pegs that connect to the main shoulders with a touch of cement gives smoother movement over time.

Technical highlights

The Minovsky flight unit is the centrepiece: a deployable wing and thruster system that lets the Xi Gundam swap between MS form and flight form without any part-swapping guesswork, just a reconfiguration of the wings and leg blades already on the kit. Robust joint components carry that transformation into stable posing on both ends, including full-wingspan flight poses that a lot of transforming HG kits can't hold. The shield's hexagonal attachment system and the accurately reproduced leg blades are the two details that read as screen-faithful once it's built.

The Xi Gundam pairs directly with the HGUC Penelope for a complete Hathaway's Flash display, and both kits are built to the same scale for a matched confrontation pose.

What Makes This Kit Special

  • MS Form to Flight Form transformation: the Xi Gundam transforms between mobile suit and flight configurations, with the Minovsky flight unit wings and leg blades reconfiguring for each mode, two distinct display options in a single kit.
  • Minovsky flight unit: the deployable Minovsky flight unit is the Xi Gundam's signature system, enabling atmospheric flight without a support craft. The wing deployment mechanism is faithfully recreated in the kit.
  • Commanding scale and presence: one of the largest and most imposing kits in the HGUC line, with a silhouette that dominates any shelf it's placed on.
  • Robust joint engineering: high-quality joint components throughout the build deliver stable posing in both MS and flight form, including dynamic action poses with the large wing units extended.
  • Full weapon loadout: beam rifle, beam saber and shield, plus five interchangeable hand parts including two open hands, unusually generous for a High Grade kit.
  • Hexagonal shield attachment: the shield attaches by displacing the arm's hexagonal parts, a design detail faithful to the Xi Gundam as depicted in the film.
  • Leg blade detail: the distinctive blades positioned on the Xi Gundam's legs are accurately reproduced, adding to the kit's visual complexity and screen accuracy.
  • Natural Penelope counterpart: released alongside the HGUC Penelope as matched kits, both at 1/144 scale, designed to display together as the central conflict of Hathaway's Flash.

Compatible Accessories

Perfect For

Intermediate builders who want one of the most visually commanding kits in the HGUC line and are comfortable with a larger, more involved build. Hathaway's Flash fans who want Mafty's Xi Gundam to face off against the Penelope on their shelf. Universal Century collectors building out the post-CCA timeline with the conflict's two central mobile suits. Builders who want a transforming kit with two distinct display configurations, MS form and flight form, in a single purchase. Anyone who wants a large-format HG kit with genuine transformation functionality that dominates a shelf without stepping up to MG scale. Not recommended as a first HGUC kit due to the part count and transformation complexity.

Fast Australian shipping

What to Watch For

Genuine builder feedback describes a stress-free, easy-to-follow build with good customisation opportunities, and more than one account says the finished kit feels closer to a Master Grade than a typical HG. One professional review recommends thickening the arm pegs that connect to the main shoulders with cement for smoother movement over time, since the sheer size of the wing units puts extra strain on that joint. No major engineering flaws were found in the sources checked.

Builder Tips: Dry-fit the Minovsky flight unit before final assembly so you know exactly how the wings and leg blades reconfigure between MS and flight form, it saves frustration mid-build. An Action Base is genuinely worth having on hand from the start, not just for flight-form poses.

Build Notes

The Xi Gundam is a snap-fit kit, no glue required for standard assembly. Due to the kit's size and weight, an Action Base is strongly recommended for flight-form display and is sold separately. Panel lining is recommended to bring out the surface and mechanical detail. Budget a full weekend session for the complete build given the part count and transformation mechanism.

Assembly Guide

SKILL LEVEL REQUIRED
Skill Level.2 Basic modeling skills are required. Parental supervision may be required for younger children. These kits are generally suitable for beginner builders. A basic set of modeling tools are required including nippers, hobby knife, sanding sticks/paper, file, and tweezers. No glue is needed for the general assembly. Parts will need to be removed by using a pair of nippers and cutting the part away from the runner. Parts may require clean-up where they were removed from the runner.
No Cement Required

Gunpla (plastic model kits) are a snap together assembly and do not need plastic cement to complete. We always recommend having some plastic cement handy as a part of your modeler's tool kit. If you prefer to fix your model in a particular pose then plastic cement will work. Plastic cement is also perfect to use if a joint is loose. Apply plastic cement in a single thin layer and allow it to dry completely before test fitting. Re-apply more cement if necessary.

No Painting Required

Gunpla (plastic model kits) are designed to be built and displayed without the need for painting. Kits are molded in different colours replicating the colours of the actual mecha from the Mecha series. A technique called colour separation, where multiple parts of the model are molded in different colours on the same sprue is also used. Mecha kits often include stickers or water-slide decals that can be applied to the model to enhance its appearance. Some Gunpla kits come with pre-painted parts or parts with pre-applied details, such as metallic or translucent finishes.

Many modelers still choose to paint their kits to customize and add further detail. Painting allows for more creativity and personalization, enabling modelers to achieve unique effects, weathering, and colour schemes that may not be available out of the box. However, the kits are designed to be enjoyable and visually appealing even without painting, making them accessible to a wide range of hobbyists.

Frequently Asked Questions

How does the MS to Flight Form transformation actually work?

The Minovsky flight unit deploys from the back and the leg blades reconfigure, so you get two genuinely different silhouettes from one kit rather than just a different pose. Dry-fit it once before your final build so you know how the parts move.

Is this a good kit for a first HGUC build?

Not as your very first one. It's rated intermediate, and the size and transformation mechanism make it more involved than a standard HG. If you've built a few snap-fit kits already, you'll be fine.

Do I need an Action Base to display it properly?

Strongly recommended, especially in flight form. A genuine Mecha Express customer review specifically calls out the Action Base 1 as the pick for this kit. It's sold separately.

What's included in the box?

Beam rifle, beam saber, hexagonal-attachment shield, five hand parts (including two open hands), the Minovsky flight unit, leg blade parts, stickers and the instruction manual.

How does it pair with the Penelope?

They were released together at the same 1/144 scale specifically so Mafty's Xi Gundam and the Federation's Penelope can face off on the same shelf, the two central mobile suits of Hathaway's Flash.

Awesome kit, great extras. Only criticism is that the kit comes with a base so you don't need the second one. The kit also doesn't have the ability to take the blue LED bonus so if you don't have another use for it it is wasted. Luckily, I'm a Gundam tragic so will always have uses for extra bases and lighting kits.

Excellent service and fast delivery

I purchased on 6 Jan and my order arrived on 13 Jan. It was very well packed, with both boxes in excellent condition. Cam even provided a small free gift in the box! Overall purchasing experience was smooth and hassle-free. I haven’t had the chance to build the kit yet, but based on the service and care taken with shipping, I would happily purchase from this store if there are other Space Battleship Yamato models available.

Very rare with fair price

If you were one of the lucky ones that were able to travel to Sydney Gundam Base pop-up in 2025 and queued extremely early (like the first 40 or so) on the first day, probably you were able to grab one of these. Otherwise, the only alternative I would know of is traveling to Japan and being uber lucky of having it still being sold at Gundam bases. Otherwise, it's a second-hand market, and prices will go up. That said, the price was fair, I think it would be similar price as using a dropship service from Japan, with the exception that it's much faster and way more guaranteed you will get proper merchandise. So, Mecha Express, Cam, thank you so much for your store!
