MULTIPLEX, a German manufacturer of high-performance remote controls for ambitious model enthusiasts, set out to modernize its entire product range – including the user interface. I have since designed each of their products, creating a cohesive, intuitive experience across the lineup. One of the key challenges was addressing the steep learning curve: flying a model airplane follows the same physics as piloting a full-sized aircraft, making control just as demanding. Through smart iconography, adaptive interfaces, and ergonomic design, the new system empowers enthusiasts to navigate these complexities with confidence.
