The discontinued GWS S17HPXN is a high-performance analog servo in the versatile Mini or Micro size class, with the ""HPX"" designation indicating ""High Power eXtreme."" The ""N"" often denotes a ""Narrow"" case or specific tuning. This servo is engineered to deliver the maximum possible torque and holding power in its category. It is a true powerhouse, designed for the most demanding applications, such as the flight controls on a large, heavy park flyer that is being flown aggressively in 3D maneuvers. It is also an excellent choice for operating high-drag devices like flaps on a scale park flyer. The S17HPXN provides the muscle to move large control surfaces with absolute authority.
The identity of the S17HPXN is its overwhelming strength. It is a servo for the pilot who needs to be absolutely certain that their control system will not be overpowered by aerodynamic forces. It provides a rock-solid, unyielding control feel that inspires the ultimate confidence, allowing the pilot to perform violent tumbles, snaps, and other high-stress maneuvers without any fear of control surface blowback.
For roboticists, the GWS S17HPXN'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 from a compact servo."
