Notes
- The discontinued Cirrus CS-402BB is a high-quality, high-torque standard-sized analog servo that focuses on delivering its power with exceptional smoothness and precision, thanks to the inclusion of a dual ball bearing (BB) supported output shaft. While still immensely powerful, this servo is aimed at applications where a refined, accurate response is just as important as raw strength. It is an excellent choice for the flight controls of a large scale or pattern aircraft, where smooth, proportional movements are key to a realistic or high-scoring flight. It is also a great steering servo for 1/8 scale on-road cars, where precision is paramount for hitting the apex of a corner perfectly every time.
- The defining characteristic of the CS-402BB is its refined power. The dual ball bearings provide a rigid, slop-free platform for the gear train, resulting in more accurate centering and a much smoother transit. This allows pilots and drivers to make very fine, precise control inputs, giving them a more nuanced and connected feel to their model. The ball bearings also significantly increase the servo's longevity, ensuring that this high level of precision is maintained throughout its service life.
- For roboticists, the CS-402BB is an excellent choice for large-scale projects that require both strength and accuracy. It is ideal for the joints of a large but precise robotic manipulator, or for a camera platform on a large rover that needs to be both strong and stable. For any robotics application where smooth motion and accurate, repeatable positioning are needed from a high-torque actuator, the CS-402BB provides a superior level of performance.
