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

Best BUILD E.V.E.R !!!

I had a week off and this set arrived just in time. It was a pleasure to build! It’s also more stable than I’d expected and there were some really interesting techniques as well.

Most Surprising Thing

It’s massive! I knew how big it would be, but still… it’s huge! I LOVE it! :D

What Can We Do Better?

MAKE MORE! (Perhaps some yellow tubes for the legs.)

Overall an amazing build

The build? Simply amazing Quality? If not for the logo missing there is no diffrence for not a lego purist Hurt fingertips? In some steps yes, but overall it wasn't that bad Would I buy this again? Absolutely

Most Surprising Thing

The sheer size of the model as well how many pieces are left over after.

What Can We Do Better?

I had 1 missing 1 by 2 black piece but it wasn't that bad. Some of the connections of armor especially the 2 front ones on the top of the legs are sca...

Absolutely perfect!!

Incredible building experience, amazing details, really helpful instructions (even if there is an illegal building technique in there somewhere 😉)

Most Surprising Thing

How stable it is when it's complete. And the sheer size of the model. I knew it was tall, but wasn't expecting it to be THAT tall!

What Can We Do Better?

No! The building experience and final model is 10/10 on all fronts! 🙏

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
