Notes
- The discontinued Cirrus CS-71BB is a premium, high-speed analog standard-sized servo that combines a fast motor with the precision of a dual ball bearing (BB) supported output shaft. This servo is designed for pilots and drivers who want both a lightning-fast response and a smooth, slop-free, and accurate control feel. It is a superb choice for the tail rotor on a .50 or .60 size helicopter, where its speed and precision work together to provide an exceptionally stable and high-performance tail. It is also an excellent steering servo for 1/10 scale on-road racing cars, where its fast, accurate response allows for precise and consistent cornering.
- The essence of the CS-71BB is its refined velocity. It doesn't just move quickly; it moves with a smoothness and accuracy that is a clear step above non-bearing servos. The coreless motor provides the instant response, while the dual ball bearings ensure that this speed is delivered without any play or imprecision. This gives the user a very high-fidelity control feel, which is essential for competitive applications where perfect control can make all the difference.
- For roboticists, the CS-71BB is an excellent actuator for tasks that require both high speed and high precision. It is ideal for building a fast and accurate robotic manipulator, a high-speed camera tracking system, or any mechanism where a combination of rapid movement and accurate, repeatable positioning is required. It offers a premium level of performance for more advanced and dynamic robotics projects.
