Notes
- The discontinued Blue Arrow S09011 is a high-speed variant in the immensely popular 9-gram analog servo class. It is a popular and effective upgrade for pilots who are looking to make their aircraft feel more responsive and agile. The S09011 is particularly well-suited for applications where quick reactions are essential. A prime example is for tail control on 450-class helicopters. A faster servo can help the gyro make corrections more quickly, leading to a more stable and locked-in tail. It is also an excellent choice for the ailerons on fast-moving park jets or flying wings, where a high roll rate is desirable for an exciting, aerobatic flight experience. It directly translates a pilot's quick stick movements into equally quick control surface deflections.
- The key characteristic of the S09011 is the swift transit time that provides a crisp and agile feel in the air. It makes an aircraft feel more "alive" and connected to the controls. For pilots who enjoy aggressive, high-energy flying, this increased responsiveness can completely change the character of their model for the better. It's an easy and cost-effective way to get a significant performance boost out of an existing airframe, simply by swapping out the standard servos for these high-speed versions.
- This speed is a significant advantage for robotics projects that require quick, repetitive motions. A roboticist could use the S09011 to build a faster pick-and-place mechanism for a small assembly task, or a high-speed sorting gate. In competitive robotics, this speed could be used to create a faster weapon system or a more agile drivetrain. Any project where the overall cycle time is limited by the speed of its actuators could see a marked improvement with the S09011.
