Quick answer

Start by dry-fitting the twin swing frame before any glue or paint to understand the transformation sequence, then tackle the morphine armor on the nose and arms as a separate sub-assembly.

Why the twin swing frame matters first

The Gatexion Mark 3 uses a variable twin swing frame that supports the GTM's transformation. If you glue or paint joints early, you may lock the frame and lose the ability to transform. Test the full range of motion before committing to assembly.

Handling the larger scale

This 1/144 kit is larger than other Five Star Stories GTMs, which means bigger parts and more surface area for seam line removal. Plan extra time for sanding and fitting, especially along the nose and arm flyer parts.

Step-by-step build process

  1. Dry-fit the twin swing frame: Assemble the inner frame without glue or paint. Cycle through the transformation three times to identify tight spots or flash that needs trimming. Mark any binding points with a pencil for later sanding.
  2. Build the morphine armor sub-assemblies: Separate the nose flyer, both arm flyers, and the vertical tail. Clean seam lines and test-fit each piece onto the dry-fitted frame before painting. Do not glue the armor panels until the frame transformation is smooth.
  3. Paint in logical groups: Prime and paint the frame, armor panels, and weapons separately. Use masking tape on the swing frame joints to keep them paint-free. A paint-free joint moves freely and avoids chipping later.
  4. Final assembly and transformation check: Once paint is cured, assemble the frame first, then attach the armor. Perform one last full transformation to confirm clearance. If anything binds, sand the painted edge slightly rather than forcing the joint.
