Notes
- The discontinued GWS S15 is a versatile and powerful analog servo in the mini class, known for offering an impressive amount of torque and a quick transit speed for its size. It is a very popular choice for a broad range of high-performance applications, including the flight controls on .25 size 3D and aerobatic aircraft, the cyclic controls for 500-class helicopters, and as a high-performance steering servo for 1/12 scale cars. The S15 is a significant step up from standard micro servos, delivering a much more authoritative and responsive control feel that is prized by performance-oriented hobbyists.
- The S15 is defined by its potent and well-rounded performance. It is both fast and strong, making it adaptable to many different demanding roles. For a helicopter pilot, it provides the speed and power needed for crisp, precise cyclic control. For an airplane pilot, it delivers the authority to handle large control surfaces during aggressive aerobatics. For a car driver, it offers a quick and powerful steering response. This versatility and high performance have made it a long-standing favorite in the mini category.
- In the world of robotics, the GWS S15 is a powerful and capable actuator for medium-scale projects. Its high torque makes it suitable for building strong robotic arms or the load-bearing joints of a walking robot. Its high speed also makes it a good choice for fast-acting mechanisms. It's an excellent all-around performer for any compact robotics project that requires a high level of performance from its actuators."
