Bandai 5072528 — HGUC RX-105 Xi Gundam 1/144 model kit  [B-5072528]

Late‑era Universal Century form and mechanical detail in 1/144 High Grade

The RX-105 Xi Gundam is presented here as a Gunpla model kit in the HGUC line at 1/144 scale. The unit originates from the Universal Century timeline and appears in Mobile Suit Gundam Hathaway, positioned as a later-generation design developed in the narrative after the major conflicts of earlier UC entries. In-universe the Xi Gundam represents a high-performance mobile suit concept intended to integrate advanced control and propulsion systems for tactical flexibility. The HGUC 1/144 adaptation translates these attributes into a High Grade kit format that emphasizes separated armor panels, articulated limb joints, and proportional silhouette suitable for display and pose experimentation.

Build complexity and tools

Difficulty: normal. Basic modelling tools recommended include side cutters, a hobby knife, fine files or sanding sticks, and small tweezers. No specialised electronics or adhesives are required for standard assembly.

Surface prep and finishing

Optional surface steps include light sanding of runner marks and seam reduction on visible panel joins; panel lines may be enhanced with washes or fine markers. Paint and topcoat choices are optional and depend on desired surface uniformity and sheen.

The kit reproduces the Xi Gundam’s late‑Universal Century silhouette through separated armor elements and a High Grade joint system that supports dynamic posing.
