The discontinued Graupner DES 566 is a powerful, high-torque digital mini servo from the high-performance DES line. This servo is engineered as a counterpart to the high-speed DES 565, with a focus on delivering the maximum possible strength and holding power. The DES 566 is a true powerhouse in a compact package, making it an excellent choice for the cyclic controls on a 500 or 550-class helicopter, where its immense holding power provides a crisp, authoritative feel. It is also a fantastic servo for the flight controls on a large, fast park jet or a heavy glider with large flaps.
The identity of the DES 566 is its intelligent, overwhelming power in a mini size. The advanced digital controller provides ferocious holding power, actively fighting against external forces to keep the control surface exactly where it is commanded. This provides a feeling of absolute, unwavering control and stability. The high-quality motor and robust gear train are all engineered to deliver this massive torque reliably, upholding the Graupner brand's reputation for durability.
For roboticists, the Graupner DES 566's massive torque in a compact mini size is an incredible asset. It is ideal for the primary lifting joints of a strong but compact robotic arm, a powerful clamping gripper, or for the leg joints of a very dynamic and powerful walking robot. It is an actuator for projects where extreme power is required, but a full standard-sized servo would be too large or heavy.
