Notes
- The discontinued Blue Arrow BA-TS-3.6 is a highly regarded member of the 'Thin Servo' family, establishing itself as a workhorse for the popular park flyer and small electric glider categories. While still impressively slim, it offers a notable step up in capability from its lighter siblings, making it a more versatile choice for a broader range of models. Its primary application remains in wing installations, where its slender profile is a significant advantage for maintaining the aerodynamic integrity of the airfoil. For sport pilots flying aerobatic park flyers or small-scale warbirds, this means cleaner lines and more precise aileron control without the need for bulky external fairings. In small sailplanes, it provides the authority needed to manage flaps and ailerons effectively, even as flight speeds increase.
- The servo is known for its commendable balance of low weight, smooth analog response, and reliability. It delivers a predictable performance that hobbyists trust, which is why it's frequently found in ARF (Almost Ready to Fly) models from reputable manufacturers. Its gear train, while not intended for extreme abuse, is well-engineered to provide a long service life in typical sport flying conditions.
- In the realm of robotics, the BA-TS-3.6’s form factor is its key selling point. It enables the design of sleeker, more compact mechanisms. For example, it could be used to create the articulated fingers of a small robotic hand where each servo must fit side-by-side, or to build a slim, unobtrusive pan-and-tilt mechanism for a small camera or sensor on a research robot. Its blend of a slim profile, dependable performance, and affordability makes it a go-to component for builders who need a capable actuator that can disappear into the structure of their creation.
