Notes
- The discontinued Cirrus CS-71 is a high-speed analog standard-sized servo, engineered as a performance-oriented counterpart to the brand's high-torque offerings. This servo's design is optimized for one thing: velocity. It is an excellent choice for applications where a rapid response is more critical than raw power. A primary use for the CS-71 is as a tail rotor servo on .30 to .50 size nitro helicopters, where its quick transit time allows it to work in perfect harmony with the gyro to deliver a stable, locked-in tail. It is also a fantastic rudder servo for 3D and pattern aircraft, enabling fast, crisp yaw-based maneuvers.
- The defining characteristic of the CS-71 is its agility. It provides an immediate, snappy response that makes any model feel more nimble and reactive. For pilots who enjoy aggressive aerobatics or the challenge of helicopter flight, the CS-71 delivers the performance needed to execute maneuvers with speed and precision. It is a servo chosen specifically to enhance a model's agility and make it feel more connected to the pilot's commands.
- In the world of robotics, the high speed of the CS-71 can be a significant asset. It's a great actuator for any large-scale project where speed is the key performance metric. For example, it could be used to create a very fast sorting or diverting mechanism on an industrial line, or to power a fast-acting launching device on a competitive robot. When a project's performance is bottlenecked by the speed of its actuators, the CS-71 provides an effective solution.
