Notes
- The discontinued Cirrus CS-601BB is a high-quality, high-torque standard-sized analog servo that is enhanced by the inclusion of a precise 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 on large scale aircraft, where the combination of strength and slop-free precision contributes to a very realistic and stable flight performance. It is also a fantastic steering servo for 1/8 scale on-road racing cars, where the precision of the ball bearings allows for perfect, repeatable cornering lines.
- The character of the CS-601BB is its "refined strength." It delivers the high torque needed for demanding applications, but the dual ball bearings ensure that this power is delivered with exceptional smoothness and accuracy. This eliminates the play that can develop in bushing-equipped servos, providing a very direct, high-fidelity control feel. The durability of the ball bearing system also ensures that this precision is maintained over a very long service life, making it a wise long-term investment for a serious hobbyist.
- In robotics, the CS-601BB is a superior choice for large-scale projects where both power and precision are key. It is ideal for building a large robotic manipulator that must perform tasks with a high degree of accuracy. It would also be an excellent actuator for a large, stable camera platform or a scientific instrument where both strength and jitter-free positioning are required. It offers a premium level of performance for demanding robotics applications.
