A step-by-step guide to assembling and adjusting the Bandai Action Base 1, posing your Gunpla, and keeping it balanced without stress on joints or plastic.

Quick answer

Assemble the base, connect the arm to the kit's back or hip using the correct adapter, then adjust height and angle before tightening. Test balance with small tilts and keep the center of gravity over the base footprint.

Why the adapter choice matters more than the arm angle

The Action Base 1 includes multiple adapters for different kit sizes and connection points. Using the wrong adapter can make the kit sit too far forward or backward, forcing you to compensate with extreme arm angles that stress the joint. Always dry-fit the adapter to the kit before attaching the arm.

When to adjust the arm versus reposition the base

If the kit leans or tips, first try rotating the base or sliding the arm mount to shift the center of gravity. Only change the arm angle if the pose itself needs adjustment. Over-tightening the arm joint can crack the plastic, so tighten just enough to hold the pose.

Step-by-step setup and balancing

Assemble the base and arm: Snap the base plate together and attach the arm to the central mount. Do not force parts; they should fit without excess pressure. Common mistake: forcing a misaligned peg can bend or crack it. Test-fit all parts before pushing them fully together.
Select and attach the correct adapter: Choose the adapter that matches your kit's back or hip connection point. Dry-fit it to the kit first, then connect it to the arm. Common mistake: using an adapter that is too loose, causing the kit to wobble. If the adapter feels loose, try a different size from the included set.
Set the arm height and angle: Loosen the arm joint, set the desired height and angle, then tighten just enough to hold. Common mistake: over-tightening, which can strip or crack the joint. Adjust in small increments. The arm should hold the pose without needing extreme force.
Mount the kit and check balance: Attach the kit to the adapter and gently rock it to see if it tips. If it does, rotate the base or slide the arm mount to shift the center of gravity. Common mistake: ignoring a slight lean that becomes a fall later. The kit should stay put when nudged lightly.
Fine-tune the pose: Make small adjustments to limb angles and weapon positions to improve stability. Keep heavy accessories over the base footprint. Common mistake: posing with limbs extended far to one side, which shifts weight off-center. Recheck balance after any pose change.
