Notes
- The discontinued Cirrus CS-75BB is a high-quality, high-torque analog servo in a standard size that is enhanced with the precision and longevity of a dual ball bearing (BB) supported output shaft. This servo is designed for applications that require both significant power and a high degree of smoothness and accuracy. It is an excellent choice for the flight controls of large sport and scale aircraft (.60 to 1.20 size), where its powerful and smooth operation contributes to a very stable and realistic flight experience. It is also a fantastic steering servo for 1/8 scale buggies and on-road cars, where its combination of strength and slop-free precision helps drivers to lay down fast, consistent laps.
- The character of the CS-75BB is its fusion of power and finesse. It delivers the high torque needed for demanding jobs, but the dual ball bearings ensure this power is applied smoothly and accurately, without the play or imprecision that can plague bushing-equipped servos. This gives the user a very direct, confident, and high-fidelity control feel. The durability of the ball bearing system also ensures this precision is maintained for a very long time, making it a great investment for the serious hobbyist.
- For roboticists, the CS-75BB is a premium choice for larger projects that require both power and precision. It's ideal for building a large robotic arm that needs to perform its tasks with a high degree of repeatable accuracy. It would also be a superb actuator for a large, stable camera platform or a scientific instrument where both strength and smooth, jitter-free motion are required. It offers a higher level of performance for more sophisticated robotics applications.
