The discontinued GWS S11 HP is a powerful, high-torque analog servo in the compact mini size class. The ""HP"" designation stands for ""High Power"" indicating that this servo's motor and gear ratio are optimized for strength and holding power. This makes it a true powerhouse for its size, designed for applications where brute force is more important than speed. The S11 HP is a premier choice for operating mechanical retracts on .25 to .40 size scale aircraft, where it has the muscle to reliably cycle the landing gear. It is also an excellent servo for operating large, high-drag flaps on a scale model or a large glider.
The identity of the S11 HP is its immense strength for its size. The transit may be slower, but this allows it to deliver a very powerful and precise movement, which is ideal for functions like flap deployment where a smooth, controlled motion is desired. For the scale modeler who needs a compact servo that can reliably operate a set of heavy landing gear or a large flap system, the S11 HP is the perfect tool for the job.
In robotics, the GWS S11 HP's massive torque in a compact size is an incredible asset. It is ideal for the primary lifting joints of a strong but compact robotic arm, a powerful clamping gripper, or for the leg joints of a very dynamic and powerful walking robot. It is an actuator for projects where extreme power is required, but a full standard-sized servo would be too large or heavy.
