Bandai 1/144 HGBC Ballden Arm Arms

Ballden Arm Arms: joints and support parts for customising HG kits

The HGBC Ballden Arm Arms (Build Custom #22) is a support set from Gundam Build Fighters Try. Bandai's idea is simple: attach it to your HG kits and make something new. It is a set of parts and joints, not a complete kit, so you need a separate HG kit to use it with.

Build difficulty

Bandai rates the set for ages 8 and up. It ships as three runners and an instruction manual, it is snap-fit, and you cut the parts from the runners with nippers. That lines up with Skill Level 2 on our scale.

Technical highlights

Bandai says the parts re-assemble from a flight form into a combined form, and that the set can be fitted to a range of mobile suits. It includes single-axis joints, two-axis joints and ball joints, and the ball joints come in three sizes. One Japanese builder notes the joint parts are made in KPS, which feels smooth and stands up well to wear, and are larger than the joints used in the All Gundam Project parts. The same builder used the set to give older kits with limited articulation more movement.

What makes this kit special

  • Joint parts set: single-axis, two-axis and ball joints, with ball joints in three sizes.
  • Two forms: Bandai describes a flight form and a combined form from the same parts.
  • Made for HG kits: designed to attach to Bandai's HG range at 1/144 scale.
  • Useful surplus parts: one builder found the leftover armour and fin parts good enough to use as they are on other kits.

What's in the box

  • Moulded parts (3 runners)
  • Joint parts: single-axis, two-axis and ball joints
  • Assembly instructions (1)

Compatible kits

Bandai designed the Ballden Arm Arms to attach to HG kits. It does not include a kit of its own, and the box says it contains one set of the Ballden Arm Arms only. Fit varies from kit to kit, so test-fit the parts before you commit to a build.

Build specifications

Build notes

Snap-fit, no glue needed. Keep a pair of nippers and a fine file or sanding stick handy to tidy the gates where parts leave the runner. Plan where each joint is going before you cut.

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 Mecha 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.

Amazing Build, my Grandson loved it!

I purchased this kit and one other for my grandsons birthday. He loved building it and found it easy to follow. My order arrived in super fast time and was beautifully packed. It even had some wonderful freebies in the box which was really great. Excellent product and service in every way!

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!
