Notes
- The discontinued Blue Arrow BA-TS-6.4 is a highly refined thin-wing servo, meticulously engineered for applications where precision and resolution are just as important as a slim profile. It is a favorite among competition pilots, particularly in soaring disciplines like F3J or F5J, where the ability to make minuscule adjustments to camber and reflex can be the difference between winning and losing. This servo is characterized by its exceptionally smooth operation and a very tight deadband, meaning there is almost no "play" or region of inactivity around the center point. This high-fidelity response allows pilots to feel intimately connected to their aircraft, enabling them to make subtle, nuanced control inputs to optimize the wing's airfoil for maximum efficiency in changing lift conditions.
- While its siblings in the TS series might be known more for raw power, the BA-TS-6.4 is celebrated for its finesse. It delivers its power smoothly and predictably across its entire range of motion, which is ideal for achieving the subtle and precise control surface deflections needed for advanced thermal soaring or for executing the graceful, flowing lines of scale aerobatics. This level of precision is a direct result of high-quality internal components and excellent quality control.
- For roboticists, this servo's high-resolution performance translates into an actuator capable of extremely fine and repeatable positioning. It is an outstanding choice for applications like camera or sensor stabilization gimbals on aerial platforms, where even the slightest jitter can ruin the data being collected. It would also excel in laboratory automation for tasks like precise valve control or as an actuator in scientific instruments that require delicate, reliable, and repeatable mechanical adjustments within a constrained space.
