The HG 1/144 Gundam Heavyarms (Clear Color) is a Gundam Base–exclusive version of Trowa Barton’s heavy-firepower mobile suit from Mobile Suit Gundam Wing. Released on January 8, 2021 at 2,090 yen (incl. tax), it is a 1/144 HGAC kit. Build difficulty sits at 1 out of 5 stars, with roughly 2.5 hours of assembly. Its highlight is the clear armor that reveals the missile pods’ inner structure, giving the build plenty of visual detail even straight from the runner. This review digs into the kit’s contents, build tips, and finishing ideas.

1. Introduction ― Trowa’s Heavyarms

In Mobile Suit Gundam Wing, Gundam Heavyarms is the heavy-firepower mobile suit piloted by Trowa Barton. It carries weapons across its entire frame yet keeps a tight, balanced silhouette, and the quiet Trowa overwhelming enemies with sheer volume of fire is a memorable image for many fans.

This review covers the Gundam Base–exclusive clear-color rendition of that machine. Having built the standard HGAC Heavyarms before, I was curious about the clear version and picked it up. Seeing the missile pod internals through the transparent armor is genuinely fun, and it’s the kind of kit you keep glancing at on the shelf. I’ll focus on what makes the clear version worth building, drawing on my experience with the standard kit.

2. Product Information

• Name: HG 1/144 Gundam Heavyarms (Clear Color)
• Series: Mobile Suit Gundam Wing
• Manufacturer: BANDAI SPIRITS
• Line: HGAC (1/144)
• Scale: 1/144
• Distribution: THE GUNDAM BASE exclusive
• Release: January 8, 2021
• Price: 2,090 yen (incl. 10% tax)
• Pilot: Trowa Barton
• Feature: Clear molding reveals the missile pod internals
• Base model: HGAC 1/144 Gundam Heavyarms (general release, October 24, 2020 / 1,650 yen incl. tax)
• Where to buy: THE GUNDAM BASE official product page and others

The clear version simply swaps the base kit’s colors for transparent runners, with a price difference of about 440 yen. Because it is a limited release, availability varies by store and timing.

3. Box Contents & Kit Layout

The kit includes:

• Multiple colored runners (clear white, clear red, clear orange, clear gray, etc.)
• One polycap runner (PC-002)
• One foil sticker sheet (for sensors and fine detail)
• One instruction manual (shared with the base model)

The core of this kit is that every color has been replaced with a clear equivalent. Even just looking at the runners, you can see the armor thickness and overlapping internal parts, making it easy to imagine the finished look before you start. Since the manual is shared with the base model, anyone who has built the standard kit will breeze through the steps.

4. Assembly ― Difficulty 1/5, about 2.5 hours

Build difficulty is 1 out of 5 stars, with about 2.5 hours of assembly. This time it came together in roughly two and a half hours. Having built the standard kit before, the steps gave me no trouble, but the clear parts introduced a few moments worth noting.

Easy-to-stumble points:

• I paused a little during gate cleanup on the clear parts. On transparent material, the cut surface shows directly in the final look, so you need to take the blade in more carefully than usual.
• The clear parts stress-mark (whiten) easily, so I worked carefully. After clipping one part, whitening appeared and I redid that spot. Leaving a little gate and trimming in two passes is the safer approach.
• The Gatling’s grip is a bit unstable, so holding it takes some fiddling. When posed in hand, the angle won’t sit steadily, so you adjust the orientation while setting it.

To fight whitening, a two-step cut followed by a fine blade pass worked well.

5. Out-of-Box Review ― Looks, Articulation, Color, Gimmicks

For a limited kit, the out-of-box result is satisfying.

The proportions hold up well: weapons cover the whole body, yet the silhouette never collapses, and lining it up with the standard kit shows off the strengths of both. Clear molding sharpens the edges of each panel, and the surfaces catch light for added depth.

Articulation is standard HG range. Holding the beam Gatling in both hands settled naturally with just a small wrist adjustment. The shoulder and leg missile pods open with a simple pinch, so the gimmicks feel light to operate.

Color separation is driven by the clear parts, so the internals show through and you sense detail even without paint. The foil stickers are only for the sensors, and leaving them off preserves the transparency better.

The biggest draw is seeing the missile pod internals through the transparent armor. Open a pod and the missiles inside are clearly visible — there’s far more detail than I expected. It’s a charm unique to this kit and absent from the standard version.

6. Place in the Lineup ― Compared with the Standard Kit

Versus the base HGAC 1/144 Gundam Heavyarms (released October 24, 2020 / 1,650 yen), the engineering and articulation are essentially identical; the difference is the molding color. The standard kit is an easier base for painting and panel lining, and suits builders who want to nail action poses.

The clear version, by contrast, offers more to enjoy straight out of the box. The see-through missile structure rewards you with discoveries after the build is done, making it ideal for display-focused builders who want to take their time with a single kit. Lined up beside the standard kit, the same machine reads quite differently.

7. One-Point Tips for a Clean Finish (general suggestions)

General advice for getting the most out of a clear kit:

• Use a fine blade and a two-step cut for gates, then tidy with sanding or compound to keep whitening down.
• Keep panel lining subtle. Clear material bleeds easily, and if you use enamel, watch for crazing and wipe gently.
• For top coat, gloss pairs well with the transparent look. Spray sparingly where you want to keep clarity.
• Limit the foil stickers to the sensors; skipping the rest keeps the transparency intact.

These are standard finishing approaches, and on a clear kit the “less is more” direction tends to shine.

8. Things to Check Before Buying

• It’s a THE GUNDAM BASE exclusive and generally won’t appear at regular shops.
• Availability varies by timing and location. Demand for the clear finish means it often trades above retail on the secondhand market.
• Secondhand stock can be found on Amazon, Rakuten, Suruga-ya, Yahoo Auctions, Mercari and similar. Prices shift with condition and timing.
• Because gate marks stand out on clear parts, keep a fine-blade nipper and sandpaper on hand.

9. Good & More

【Good】

• Opening the missile pods reveals the internals through the clear armor — a highlight the standard kit lacks.
• The Gatling and missile pod deploy gimmicks actually move, making it fun to try out pose variations.
• It looks great even unpainted, so a no-paint build like mine still feels satisfying.

【More】

• Holding the beam Gatling in hand makes the angle drop, so you need to plan the display orientation.
• Clear parts leave white gate marks easily; I re-trimmed one spot. A fine-blade nipper and sandpaper are worth having ready.
• Some foil stickers break up the transparency, so I applied only the sensor pieces.

10. Score

Overall: ★★★★☆

In a word: “A clear exclusive that shows its internals out of the box and is a joy to display.”

11. Wrap-Up

That’s the review of the HG 1/144 Gundam Heavyarms (Clear Color). Even with experience building the standard kit, the clear version offers a different kind of fun. The see-through missile structure rewards you with discoveries after the build, and you’ll find yourself looking at it for a while.

That said, gate cleanup on the clear parts and the Gatling’s grip take a little extra care, so it suits builders who want to go slow and tidy. If you prefer a quick build or want rock-solid action poses, the standard kit may be easier to handle. For Gundam Wing fans who want to take their time on one display piece, this clear-color version is a genuinely interesting choice.
