The Tamiya 69920 Cross Universal Arm Set supplies clear structural pieces suited to small-scale models and classroom workshops. The transparency helps you view linkages and wiring while keeping the layout tidy during trials and iterations.
This pack includes four 80mm by 80mm cross arms that are useful for frames and linkages. Each arm is drilled with 3mm holes spaced at 5mm intervals, offering flexible mounting points for plates, gearboxes and add-on modules during iterative builds.
The clear plastic is handy when adding lighting or routing wires close to visible areas, and works well alongside clear Tamiya plates, gearboxes and wheels. Plan LED placement early to make the most of the translucency for visual demos.
Arms can be cut to shape, painted or glued as needed; testing with scrap pieces is advised before finalising. The included screws and spacers give you quick assembly options for prototyping and classroom projects.
