Notes
- The discontinued Blue Arrow S04310 is a highly capable 4.3-gram class analog servo that skillfully bridges the gap between the smaller micro servos and the larger, more powerful mini-class servos. It is an excellent fit for a new tier of aircraft, including larger park flyers, smaller electric gliders, and particularly for hand-launch gliders (HLGs) or discus-launch gliders (DLGs), where a bit more power and durability are required to handle the higher launch stresses and faster flight speeds. The S04310 provides a noticeable increase in control authority, giving pilots a more solid and connected feel to their aircraft. This is especially important for gliders, where precise control of the camber-changing flaps and ailerons is critical for maximizing lift and efficiency.
- This servo is particularly appreciated by hobbyists for its very smooth gear train and solid, reliable centering. Compared to some of the smaller pico servos, it offers a more refined and high-quality feel in its operation. This smoothness translates into more fluid and proportional control surface movements, which is highly desirable for pilots flying graceful aerobatics or trying to execute a perfect landing approach. It represents a step up in both power and refinement, making it a popular upgrade for modelers looking to enhance their aircraft's performance.
- In robotics, the S04310 is an excellent choice for builders looking to create more robust and capable small-scale projects. It has enough power to build a more substantial pan-and-tilt turret for a larger sensor or camera. It's also an ideal actuator for the limbs of a small walking robot or for creating larger, more functional grippers that can manipulate a wider range of objects. It's the logical next step for projects that have exceeded the physical limits of the 3-gram class servos.
