The discontinued Graupner DS 277 is a high-quality digital servo in the popular sub-micro class (typically 9-12 grams), designed to be a superior, all-around performer. It brings the precision and holding power of a digital controller to a compact package, making it an excellent upgrade for high-quality park flyers, small electric aerobatic models, and 450-class helicopters. The DS 277 is built to the high standards of the Graupner brand, offering a smoother gear train and more reliable performance than many other digital servos in its class. It provides a crisp, responsive, and locked-in feel that can transform the handling of a small model.
The character of the DS 277 is its refined digital performance in a small size. It is a servo for the discerning pilot who wants the best possible control feel from their small aircraft. The digital controller provides the strong holding power for aggressive maneuvers and the precise centering for stable, predictable flight. It is a premium component that enhances both the performance and the enjoyment of flying.
In robotics, the Graupner DS 277 is an excellent choice for small-scale projects that require a high degree of precision and reliability. Its digital holding power is ideal for the joints of a small walking robot, while its precision makes it a great choice for a small, accurate robotic manipulator or sensor turret. It is a high-quality building block for creating more sophisticated and capable micro-robotic systems.
