Notes
- Not to be confused with the smaller sub-micro 241, the discontinued S241 is a standard-sized analog servo that built a strong reputation as a reliable workhorse. It was widely regarded as a smart, affordable upgrade from the basic servos typically bundled with ready-to-run kits, offering hobbyists a significant boost in both durability and precision for their models.
- The S241's design philosophy prioritized robustness. It featured a durable, all-metal gear train, giving it superior resistance to damage from shock and high-load situations. This was a key reason for its popularity in demanding applications. Furthermore, its output shaft was supported by a ball bearing, a feature that set it apart from entry-level options. This ball bearing reduced friction and helped maintain tight, precise control by minimizing the development of gear slop over the servo's long service life.
- Thanks to its solid construction, the S241 was remarkably versatile. Modelers confidently used it for primary flight controls like aileron, elevator, and rudder on a wide range of sport aircraft. Its resilience also made it a trusted choice for managing the throttle on glow-powered helicopters and for the steering systems in radio-controlled cars and trucks. While the technology has since advanced, the JR S241 is remembered as a classic example of a dependable, well-engineered servo that delivered consistent performance for countless hobbyists.
