In 1986, Castle advanced with the Black Falcon’s Fortress and new armor elements, while Town and Space received steady expansions. Technic deepened its engineering focus with more gears, linkages, and pneumatics, and began limited experiments with computer-assisted control in educational contexts—precursors to later robotics lines.
