Key features
  1. Detachable transforming Core Fighter: lifts straight out of the chest and rebuilds into jet-fighter mode, so one kit gives you two things to display.
  2. Opening hatches over a visible inner frame: panels across the body swing open to show the mechanical detail underneath, which is the whole reason to build this in 1/100.
  3. First-wave 1997 Master Grade: one of the early kits that set the template for the MG line, and a genuine piece of Gunpla history for a Universal Century shelf.

Series Assembly Guide FAQ

Bandai 1/100 MG Gundam GP01 U.N.T Spacy Prototype

The prototype Kou Uraki never asked for

Stardust Memory opens with a test pilot, a quiet colony dock and two brand new Gundams nobody outside the Earth Federation was supposed to know about. The RX-78GP01 "Zephyranthes" is the one Kou Uraki takes up, and it is deliberately the least dramatic of the Gundam Development Project units. No nuclear bazooka, no giant shoulder binders. Just a clean, purposeful update of the original RX-78 silhouette built for general-purpose combat.

This is the 1997 Master Grade of that suit, and it is a proper piece of Gunpla history. It sits in the first wave of the MG line, back when a detachable Core Fighter and a full inner frame were still genuinely new ideas.

Build difficulty

Ten runners plus polycaps. It is snap-fit, no glue needed, and every part is moulded in colour, so a straight build looks right without a drop of paint. Expect a comfortable evening or two rather than a marathon. The engineering is 1997-era, which means the inner frame is simpler and the tolerances are looser than a modern Ver 2.0 kit, so take your time on the polycap joints and do not force anything. If you have finished a couple of HG kits, this is a very fair first Master Grade.

Technical highlights

The Core Fighter is the headline. It pulls out of the torso and rebuilds into a jet-fighter mode, which is the gimmick the GP01 is known for. Inner mechanical detail runs through the frame and hatches open across the body to show it off. Articulation comes from polycap joints, and you get the standard Federation loadout: beam rifle, beam sabre and shield. Markings are handled by foil stickers, dry transfers and clear stickers, which is how MG kits of this era did decals.

What makes this kit special

  • Detachable Core Fighter: lifts out of the chest and converts to fighter mode, so you can display the suit and the fighter as two separate pieces.
  • Opening hatches and visible inner frame: panels across the body open to reveal the mechanical detail underneath.
  • First-wave Master Grade: a 1997 release and one of the kits that set the template for what MG means.
  • Colour-moulded, snap-fit: no paint or glue required for an accurate finish.
  • Three marking types: foil stickers, dry transfers and clear stickers included.

What's in the box

  • Ten runners of injection-moulded parts

  • Detachable Core Fighter parts
  • Beam rifle

Compatible accessories

No display base is included with the kit. For dynamic poses of the GP01 and its detached Core Fighter, pair it with the Bandai Action Base 4, the standard 1/100 display stand.

Build your Stardust Memory collection

The obvious companion is the later-spec version of this same suit, the Bandai 1/144 HGUC RX-78 GP01Fb, which is the Full Vernian refit Kou switches to for space combat.

If you are building out the Universal Century shelf in Master Grade, the Bandai 1/100 MG Gouf Ver 2.0 and the Bandai 1/100 MG RX-93 Nu Gundam Ver. Ka are both in stock.

What to watch for

I went looking through builder discussion for recurring problems with this kit and did not find a repeated, independently confirmed fault. What comes up consistently instead is its age. Builders treat it as a vintage build and generally report it as a fun one, with more than one describing the GP01 and its Full Burnern sibling as good builds.

What is worth knowing going in is simply what a 1997 Master Grade is. The inner frame is less involved than the Ver 2.0 kits that came a decade later, articulation is polycap-based rather than a modern engineered frame, and the markings are stickers and dry transfers rather than the waterslide decals you get on newer MGs. None of that is a fault. It is just a different generation of kit, and it is worth setting expectations against a modern MG rather than assuming they build the same.

Builder tips: dry transfers need a firm, even rub with a blunt tool and they are unforgiving once down, so line each one up before committing. Work the Core Fighter parts slowly the first time you separate them. A light panel line with a Gundam Marker sharpens the chest and skirt armour more than anything else you can do to this kit.

Build notes

No glue and no paint required. Nippers and a hobby knife are enough, though sanding sticks help clean up nub marks on the white armour where they show most. Budget two to four hours across a session or two. Recommended age 15 and over.

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

What makes these Gunpla kits the hottest sellers?

These kits are fan favourites for their detailed design, affordability, and build size, offering a balanced and enjoyable building experience.

Are these hottest seller kits suitable for beginners?

Absolutely! Especially the HG kits, which are known for their fewer parts and simplicity, making them a great starting point for new builders.

What is the level of detail in the MG and RG hottest sellers?

MG kits boast a detailed inner frame and additional parts, while RG combines MG’s complexity with HG’s size for an intricate, compact build.

Can I get replacement parts if I lose some during the build?

Yes, if you buy a kit from Gundam Express Australia we will source replacement parts for you. This is not a quick process as parts need to come from Bandai in Japan.

How much space will I need to display these Gunpla?

HG and RG Gundam kits are compact, while MG Gundam are larger but still manageable. You won’t need too much space to showcase these masterpieces beautifully.

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!
