Notes
- The discontinued Cirrus CDS751 is a specialized digital servo engineered with a singular focus: delivering the maximum possible torque and holding power in its class. While it shares the precise digital controller of the CDS750, its motor and gear train are optimized for brute strength rather than outright speed. This makes it the ultimate choice for applications where the servo must fight against significant external forces. A prime example is the steering system on a heavy 1/10 scale monster truck or a rock crawler. The CDS751 has the raw muscle to turn large, heavy tires against the friction of tough terrain or the binding forces of a rock crevice. It is also an excellent choice for operating large flaps or other high-load control surfaces on scale aircraft.
- The identity of the CDS751 is forged in power. Its ability to hold a commanded position without yielding is its greatest strength. For a monster truck driver, this means the vehicle tracks straight and true, even when landing from a big jump. For a scale pilot, it means the flaps deploy smoothly and hold their position without being pushed back by the airflow. This servo provides the ultimate authority, giving the user confidence that their commands will be executed without compromise, regardless of the load.
- In robotics, the CDS751 is a compact powerhouse. It is an ideal actuator for a heavy-lifting robotic arm, a powerful clamping gripper, or the primary load-bearing joints of a substantial walking robot. Its immense holding power is also perfect for any robotic application that requires maintaining a static position against a strong, continuous force. When a project's success depends on a servo that will not back down, the CDS751 delivers the required strength.
