The Graupner DES 585 BB is a high-quality digital servo from the esteemed DES line, housed in a unique, slim "wing servo" profile. This servo is engineered to bring digital precision to the most aerodynamically sensitive applications. It features a responsive digital controller and a smooth, dual ball bearing (BB) supported output shaft, all in a thin case designed for internal wing mounting. It is a premier choice for the ailerons and flaps on high-performance sailplanes and jets, where a clean airfoil is essential and precise, repeatable control is demanded.
The essence of the DES 585 BB is its digital precision in a sleek, low-drag package. The digital controller provides a level of holding power and centering accuracy that is a massive advantage for a glider pilot trying to hold a precise camber setting. The dual ball bearings ensure that this precision is delivered with a silky-smooth, slop-free motion. It is an instrument-grade component for the competitive soaring pilot.
For roboticists and custom designers, the Graupner DES 585 BB's slim profile and digital precision make it a unique and powerful tool. It is the perfect solution for any project that requires a precise actuator to be placed in a very narrow space. It could be used to create the articulated fingers of a high-fidelity robotic hand or for an actuation system within a streamlined, high-speed vehicle where both precision and a low profile are required.
