Building the MG Nu Gundam Ver. Ka Fin Funnels

The MG Nu Gundam Ver. Ka is a superb Master Grade kit, but its fin funnel system can turn an enjoyable build into a patience test. The funnels are small, layered, and repeated six times, so tiny inconsistencies become obvious when they are mounted on the backpack.

A careful approach makes the process far less intimidating. Rather than treating the fin funnels as six identical chores, break each unit into repeatable stages: nub removal, frame assembly, armour fitting, articulation checks, and final alignment.

For Australian builders, planning ahead also matters. Local hobby shops in Sydney, Melbourne, Brisbane, and Perth may carry the kit intermittently, while online orders can involve expensive postage or delays through customs. Buying spare sanding sticks and paint supplies with the kit can save a second shipping bill.

This project rewards a clean work area, good lighting, and a willingness to pause. The fin funnels are display pieces in their own right, so rushing them can undermine an otherwise excellent Nu Gundam build.

Preparing The Runners And Workspace

Before cutting anything, arrange the runners in numerical order and identify the parts belonging to the fin funnels. The instructions move quickly between frame and armour pieces, and a divided parts tray prevents the common mistake of mixing nearly identical components.

Use a sharp side cutter for the first cut, leaving a small nub for a second pass. A hobby knife can then level the remaining mark, followed by a fine sanding stick. On dark blue or navy plastic, careless scraping may leave a pale stress mark, so controlled pressure is more important than speed.

The funnels are easier to inspect under a desk lamp than under a ceiling light. Australian summer heat can make plastic feel slightly softer, especially in a warm hobby room, so avoid forcing parts together after the kit has been sitting in direct sun.

Building One Funnel As A Master

Build the first fin funnel slowly and treat it as your reference unit. Confirm which side faces the backpack, how the internal hinge folds, and where the armour locks over the frame. Do not immediately repeat the process six times; the first completed funnel often reveals a hidden assembly detail.

The internal mechanism needs freedom to move, but it should not feel loose. If a hinge is stiff, inspect it for a leftover nub or mould line before reaching for extra force. A tiny amount of friction is useful because the funnel must hold its position in a display arrangement.

This method resembles the careful mechanical inspection used in PG Zaku articulation, where movement and gimmick reliability matter as much as surface appearance. The Nu Gundam’s funnels are smaller, but the same principle applies: test the mechanism before enclosing it.

Repeating The Six Units

Once the first funnel works correctly, repeat the build in batches. Complete all six inner frames first, then fit the corresponding armour panels. Batch building reduces mental switching and makes it easier to spot a missing piece or reversed hinge.

Keep completed funnels in a row and compare their silhouettes. Look at the pointed ends, panel gaps, and hinge angles from the front and side. Slight differences are normal, but a funnel that sits noticeably wider or flatter usually has a panel fitted at the wrong angle.

Do not use cement on the moving sections. The tolerances are designed for articulation, and glue can permanently seize a joint. If an armour piece is too tight, remove a minimal amount from the hidden peg or edge, then test again rather than shaving visible surfaces.

Managing The Backpack Connection

The backpack connectors carry the combined weight of the fin funnel system, so inspect every attachment point before loading all six units. A loose connection may seem harmless on the bench but become obvious when the Gundam is standing on a shelf for weeks.

Install the funnels one at a time and support the backpack with your other hand. This avoids placing sideways pressure on the central mount. If you intend to use the included display arrangement, establish the pose before applying decals or top coat, since repeated handling can catch waterslide edges.

Builders who enjoy crossover projects may appreciate the lessons in RG Eva Unit-01, particularly the value of checking balance before committing to a dramatic pose. The Nu Gundam looks powerful with the funnels deployed, but stability should come first.

Painting, Panel Lining And Decals

The fin funnels have enough surface detail to benefit from restrained panel lining. Use a fine grey or dark blue wash rather than a heavy black line across every recess. Excessive contrast can make the small units look busy, especially against the Nu Gundam’s clean white armour.

If painting, keep coats thin around hinges and connector sockets. Acrylic hobby paints are widely available through Australian specialist shops, while local chains may have limited Gundam-specific colours. Test your paint mix on a spare runner before applying it to the visible funnel armour.

Decals are best added after the funnel geometry is final. Work with one unit at a time, blot water carefully, and allow each marking to dry before handling the next. A satin or semi-gloss finish can protect the markings without making the entire mechanism look overly glossy.

Displaying The Finished System

The fin funnels can be attached in their compact backpack configuration or spread into a firing pattern with an action base and suitable support arms. A dramatic arrangement needs more space than many standard shelves provide, so measure the intended display area before committing to the pose.

In Australia, dust can become a persistent issue during dry periods, particularly in inland areas and heated rooms. A glass cabinet or occasional soft makeup-brush cleaning will help preserve the white armour and prevent grit from entering the hinge joints.

The build also works as a reminder that a kit’s appeal does not depend entirely on knowing its original series. The broader enjoyment described in building unfamiliar series kits applies here: mechanical design, construction rhythm, and shelf presence can stand on their own.

Practical Habits For A Cleaner Build

A few habits make this fin funnel assembly more reliable and less repetitive:

• Label six small trays or sections for the individual funnel units.
• Photograph the first completed funnel before beginning the remaining five.
• Check every hinge for nubs before fitting the outer armour.
• Use a sanding sponge rather than aggressive pressure on visible edges.
• Test backpack connections before adding decals or top coat.
• Keep spare supports available for an extended firing pose.
• Store unfinished funnels in a sealed container away from dust and pets.

The MG Nu Gundam Ver. Ka’s fin funnels are demanding because they combine repetition, articulation, and visual symmetry in a compact package. Take your time, compare each unit against the first, and share progress photos or troubleshooting notes with the Gundam Eclipse community. Your finished build can give another Australian modeller the reference they need to tackle the same impressive system.
