Detailed Head Disc
1

Detailed Head Disc

The most recognisable feature of the Tallneck is intricately designed and securely held up by the just-as-detailed neck.

Technic Re-enforced Skeleton
2

Technic Re-enforced Skeleton

Standing at 94cm tall requires serious structural integrity. A Technic skeleton provides all the support needed to confidently prop up the beast to prevent it from crashing into a pile of bricks in-case of knocks from a specific friend of the furry kind.

Integrated Display Base
3

Integrated Display Base

The model sits securely on a clean display base that provides the stability for the build, but also elevates it to a model worthy of becoming the centrepiece of your collection.

Our thoughts on the design

The Tallneck is undoubtedly the most impressive of SerialBuilder's designs as it's just humongous! What's most impressive about it is its accuracy and how well the stance has been captured. The build is solid, and will stand up well against time. There are a few connections for the armour plating that could do with an extra stud, but since it's a display piece and not a play model, it doesn't matter too much. This build is a must-have if you're collecting the series - there's nothing quite like it.

Fixes we've made

Reinforced neck structure

The original build suffered from the neck leaning back over time ultimately affecting the overall pose. The neck section of the skeleton has been updated to ensure that the Tallneck keeps its iconic pose for years to come.

Severity: High

Toe subassembly connections improved

The way the toes are attached to the build, whilst being very clever, was able to be knocked out of position easily if not handled carefully. We replaced the connections points to be much stronger and now the toes will not pop-off so easily.

Severity: Low

Amazing

Definitely the star of the collection, cosmetically at least. The sheer size of it draws attention to it basically anywhere you put it

Most Surprising Thing

Surprised me a bit with the height, I'll need to make a custom shelf to make it fit inside my room

What Can We Do Better?

The head is attached very poorly and falls off very easily, which happened to me two or three times during the building process

The taller, the better

Again, an amazing build !!! I've waited for my week off to build this beast, and i was not disappointed. Its not tall, its gigantic!!! I enjoyed building it (maybe too fast) and i love the result. Like the other builds, it is not an easy one. There a lot of "technic" steps, lot of pins that must be perfectly aligned, etc... Its fairly steady. I moved it from my desk to my TV stand, not had a single problem. Some junks may feel a bit weak, but im not going to play with it, so thats ok. Also some repetitive steps (of course, its symemtrical). Im now looking for a good way to light it. If you have any recommandations.

Most Surprising Thing

The size. It was a surprise until the very end, making the building experience perfect!!!

What Can We Do Better?

Some choice are questionnable. I dont really like the bending axel at the base of the neck (ok it makes it more stable, but its a big inconvenience if...

TALL Ambitions to Neck-breaking Heights

Absolutely Amazing! Out of all three gigantic sets, this is my favorite. When building it at the table, you will feel dwarfed by this set and get an inkling of what it must be like to see in real life, or VR.

Most Surprising Thing

The sheer size, the details, such as toes and the neck Armor. It feels more robust than I had expected and what I am used to from comparable builds by...

What Can We Do Better?

As always everything was great. I only have three recommendations for the instructions: -I believe I mentioned it in The tremortusk review, but just i...
