FM 1/100 Gundam Aerial vs GK Conversion Kit — Which Is Right for You?

FM vs GK: Do You Actually Need a Resin Conversion Kit for Your Gundam Aerial? Stock FM vs. Damo GK original vs. GHS redesigned version — a clear-eyed guide to which option is right for your build level
Three Options, One Decision
If you're building the Bandai FM 1/100 Gundam Aerial and you've seen display-grade builds online, you know the difference is real. The question is what's actually driving that difference — and whether it's worth what it costs.
There are three paths: the stock FM, the Damo Studio (大魔工作室) original GK conversion, or the GHS (Galaxy Hobby Studio) redesigned version. This guide breaks all three down without overselling any of them.
Why the FM Kit Is Already Good
FM (Full Mechanics) is Bandai's line for 1/100 scale kits with inner frame detail and multi-piece armor construction. The FM 1/100 Aerial is widely considered one of the best in the line:
✓ Accurate silhouette to the animation
✓ Functional Bit Stave deployment
✓ Well-engineered inner frame with meaningful articulation
✓ Clean panel lines out of the box
✓ Multi-color molding reduces painting needs
Many accomplished builders in Chinese and Japanese communities have created award-quality work from the FM base alone through custom scribing and paint. So why add a GK kit?
Understanding the Two GK Versions
Damo Studio (大魔工作室) — The Original GK
Damo Studio was among the first to develop a full-body GK conversion for the FM 1/100 Aerial. The early community builds on Bilibili and Douyin that shaped expectations for what a "display-grade Aerial" looks like are largely Damo versions. Solid proportional corrections, clean casting — but no masking tape, minimal documentation, basic or no decals. You solve the build workflow independently.
GHS (Galaxy Hobby Studio) — The Redesigned Version
GHS developed their version as a comprehensive redesign, not a reprint. They kept what Damo established and built on top of it: deeper panel scribing, sharper edge geometry, a pre-cut masking tape set matched to the GHS layout, a full-color digital manual, and a dedicated waterslide decal sheet. More expensive than Damo, but the extras are substantive.
FM vs. Damo GK vs. GHS GK — Full Comparison
| Factor | Stock FM Aerial | FM + Damo GK | FM + GHS GK |
|---|---|---|---|
| Total cost | ~$40–55 | Lower than GHS | ~$130–145 |
| Build time | 5–10 hrs | 20–40 hrs | 20–50+ hrs |
| Skill level | Beginner+ | Intermediate+ | Intermediate–Advanced |
| Panel line depth | Moderate | Deep | Very deep |
| Masking support | N/A | Self-managed | Pre-cut tape included |
| Documentation | Bandai manual | Minimal | Full-color digital manual |
| Waterslide decals | Bandai sheet | Basic or none | GHS-specific sheet |
| Result ceiling | High | Very high | Very high |
Which Option Is Right for You?
Stock FM Only — If:
- This is your first or second Gunpla build
- You prefer no-paint or minimal-paint builds
- You want a finished model in a weekend
- You're testing whether you like the Aerial design before committing
Damo Studio GK — If:
- You're an experienced builder who prefers to manage masking independently
- You want the original GK version at a lower price point
- You don't need the extra documentation and extras the GHS version adds
GHS Redesigned Version — If:
- You want masking and documentation handled for you
- You're building for photography, competition, or display focal point
- You have or are ready to invest in airbrush equipment
- You want the most detail-complete version of the Aerial at 1/100 scale
A Realistic Build Progression
- 1. Build the FM Aerial normally — understand the inner frame structure, learn where every part goes.
- 2. Panel line and topcoat the FM build — this teaches basic masking and finishing without resin complexity.
- 3. Add scribing or minor modifications — develops hand-control skills that resin work requires.
- 4. Build the GHS GK version — with the FM build as reference, assembly is much easier. You know exactly where every part goes.
Frequently Asked Questions
Q: If I've already built the Damo version, is it worth doing the GHS version?
For most builders — probably not both. The GHS version's primary advantages (masking tape, manual, deeper panel lines) are most valuable before you've developed the workflow independently. If you've done a successful Damo build, you've already solved those problems. The visual difference between a well-executed Damo build and a well-executed GHS build is real, but not worth the full cost of doing both unless it's a specific project goal.
Q: Can I practice GK building on a cheaper kit before the Aerial?
Yes — this is actually recommended. Many builders do their first GK on a smaller, less expensive kit before tackling a full 100+ part conversion. The skills (resin washing, gate removal, resin fit) transfer directly.
Q: Can I use a previously built FM Aerial for the GK conversion?
Yes — unsnap the plastic exterior armor from the inner frame. The inner frame is what you're keeping. The GK shells attach to the same connection points.
Q: Does the GK conversion affect articulation?
Both Damo and GHS kits are designed to maintain the FM Aerial's articulation. Resin shells replace the plastic armor but don't lock joints. Some extreme poses may have slightly reduced range due to tighter tolerances, but standard display poses are unaffected.
Q: Is the visual difference between Damo and GHS noticeable in person?
Yes, primarily in panel line depth and edge sharpness — most visible under angled lighting and in macro photography. The more significant visible difference between any GK version and the stock FM is finish quality (airbrushed multi-tone vs. box-built), not the GK parts themselves. The masking-enabled color separation is visible at any distance.
