Notes
- The discontinued Blue Arrow S0361 is a classic analog micro servo that occupies the highly popular 3.6-gram weight class. It represents a significant step up in size and power from the ultra-light pico servos, making it an excellent choice for aircraft that require a bit more control authority and are less than 2 ounces total. It is perfectly at home in a wide range of park flyers, small electric gliders, and as a cyclic servo on many micro-helicopters. The S0361 provides the extra muscle needed to move larger control surfaces with confidence, or to withstand the higher aerodynamic forces encountered by slightly larger and faster models. It successfully bridges the gap, offering a substantial performance increase without a major weight penalty, which is critical for maintaining the agility of lightweight aircraft.
- The S0361 is celebrated throughout the modeling community for its durability and reliability in a small package. It has earned its status as a trusted workhorse for everyday sport flying. Hobbyists appreciate its smooth gear train and consistent centering, which contribute to a stable and predictable flight experience. It's the kind of component that builders can install and then largely forget about, knowing that it will perform its duties reliably for a long time. This dependability is a key reason for its enduring popularity in a market filled with countless options.
- In the world of robotics, the S0361 hits a critical sweet spot. It provides a noticeable increase in power over the 2.5g servos, allowing for the creation of more capable mechanisms. It's strong enough for the leg joints on a small walking robot that needs to carry its own battery pack, or for building a small robotic arm that can actually lift and manipulate lightweight objects. It's the ideal choice when a robotics project has graduated from the "ultra-light" phase and needs a more substantial, yet still compact, actuator.
