Notes
- The discontinued E-flite S90 is a robust and powerful standard-sized analog servo, designed to provide the muscle needed for larger aircraft in the E-flite and Hangar 9 lineups. This servo is engineered for applications that require a significant amount of torque, such as the large flight controls on .40 to .60 size electric and glow-powered sport and scale aircraft. It is also a very capable and durable servo for operating high-drag devices like flaps or mechanical retracts. The S90 is built to a high standard of quality, with a strong gear train and a reliable motor to ensure safe and authoritative control of larger, heavier models.
- The core character of the S90 is its dependable strength. When flying a larger aircraft, the reliability and power of the control system are paramount. The S90 provides the peace of mind that comes from a well-engineered, powerful servo from a trusted brand. It delivers a solid, confident feel to the controls, ensuring that large control surfaces move with precision and hold their position firmly against the aerodynamic forces of flight.
- In robotics, the S90's high torque and quality construction make it an excellent choice for more demanding projects. It is a great actuator for building a large, functional robotic arm capable of lifting significant weight, or for the primary drive joints of a medium-to-large walking robot. For any robotics project that requires a strong, reliable, and high-quality standard-sized servo, the S90 is a superb option."
