Brick Gundam MOC: Frame-First Build Guide for Beginners

Here is the short answer up front: a brick Gundam MOC is not as hard as it looks. Once you understand the core principle — build the frame first, hang the armor on afterward — an ordinary builder can assemble a poseable mecha about 30 cm tall using roughly 3,000 pieces and a budget of about 300 CNY. This guide walks you from the skeleton, through armor coverage, to the final detail pass, so you can finish your own first brick Gundam.

Step 1: Choose a Scale and Build the Frame

Decide on a scale before you touch a single brick. A 1/100 scale mecha usually stands 25–30 cm tall and needs around 2,500–3,500 pieces. A 1/60 scale build goes past 40 cm and nearly doubles the part count. Beginners should start at 1/100 — it is cheaper, easier to handle, and still large enough to hold detail.

The frame is the soul of the MOC. Use technic parts for the joints, and beams and pins to build the basic framework of the torso and limbs. Make sure the shoulders, elbows and knees can all move. Give each joint a real range of motion before you bury it in armor, because retrofitting articulation later usually means tearing the model apart. Once the frame is standing, test its stability on its own — if it wobbles or tips at this stage, the finished model will only be worse. Fix the balance now, then move on.

A practical tip: build the legs and hips first and check that the figure stands unaided, then add the torso, then the arms and head. Working upward keeps the center of gravity predictable.

Step 2: Armor Coverage and Color Scheme

This is the layer that decides how your Gundam looks. Cover the frame with plates first, then work through three progressive layers: outer armor, inner structure, and fine detail. Resist the urge to jump straight to the surface — the frame should stay visible in the gaps between armor panels, which is what gives a mecha its mechanical look.

On color, keep it to no more than three main colors. The classic white, blue and red combination works well, with dark parts used as accents at the joints. A tight palette reads as a designed machine; too many colors reads as a parts bin.

If you are missing parts in a specific color, look for alternatives on brickplan.cn or trade pieces with other builders rather than compromising the scheme. And do not forget to plan your weapon mounts: leave exposed studs on the back and on the arms so weapons and a backpack can be attached later.

Step 3: Details, Stickers and Display

Finish with the small parts — antenna, thrusters, cockpit. Stickers or printed parts add a lot of perceived quality for very little cost. When the model is complete, check the full range of motion again and make sure armor panels do not collide with each other when the limbs bend; interference at the shoulders and knees is the most common problem at this stage.

For display, a simple base makes a real difference, and it also helps a top-heavy figure stay upright.

On time: a 3,000-piece build takes about 8–10 hours once you are experienced. Beginners should spread it over three days, one section per day. The pace is better and you make fewer mistakes.

FAQ

Q: How many parts and how much budget does a brick Gundam MOC need?

A: A 1/100 scale brick Gundam MOC needs roughly 2,500–3,500 pieces and a budget of 300–500 CNY. Beginners can start by modifying an official set into a MOC — it costs less and is easier practice.

Q: Can I build a brick Gundam without instructions?

A: Yes. Build the frame first, then cover it with armor, using reference photos of real models and the structure of official sets as a guide. If you want to save time, you can download ready-made MOC instructions on brickplan.cn and follow the steps.

Q: What is the difference between a brick Gundam MOC and a Bandai Gundam model kit?

A: A brick MOC can be freely disassembled and rebuilt, and the parts are highly interchangeable, which suits builders who like to modify. Bandai kits offer high precision and need no tools for assembly. The two playstyles differ, so pick whichever you prefer.

Q: How do I stop my model from falling apart halfway through?

A: A solid frame is the key. Interlock joints with technic pins, press armor pieces fully into place layer by layer, and test the sturdiness of each section as you finish it. Doing this greatly reduces the chance of a collapse.

One last note: the fun of MOC is constant improvement, so after you finish your first build, take it apart and try again with what you learned. You are also welcome to share your work on brickplan.cn and swap tips with other mecha builders.
