The GWS Park HPX is a high-performance analog servo in the versatile "Park" flyer size class, with the "HPX" designation indicating "High Power eXtreme." 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 Park HPX provides the muscle to move large control surfaces with absolute authority.
The identity of the Park HPX 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 Park HPX'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.
