The discontinued GWS S11F CL is a high-performance analog servo in the mini class that combines two speed-enhancing technologies: a ""Fast"" (F) gear train and a high-quality coreless motor (""CL""). This servo is a dedicated speed demon, engineered for the most demanding competitive applications where velocity and responsiveness are paramount. The S11F CL is a premier choice for the tail rotor on a 500-class helicopter, where its incredible speed is essential for a perfectly locked-in, professional-level tail. It is also an outstanding servo for the flight controls on a high-speed pylon racer or ducted fan jet.
The defining characteristic of the S11F CL is its single-minded pursuit of velocity. The combination of a fast-revving coreless motor and a high-speed gear ratio results in a servo that moves with almost zero perceptible lag. For the competitive pilot, this provides a massive advantage, allowing for instantaneous corrections and a level of agility that is second to none. It is a specialized instrument for the pure speed enthusiast.
While highly specialized, the extreme speed of the S11F CL can be harnessed by roboticists for unique projects. It would be an excellent actuator for a high-frequency research application, such as controlling a vibrating platform or an optical chopper wheel. For any compact robotics project where the absolute maximum speed is required from the actuator, the S11F CL is a specialized and highly capable tool."
