Notes
- The discontinued Align DS610 is a high-torque, standard-sized digital servo that has earned a legendary reputation for its power, precision, and durability. It is the go-to choice for the cyclic controls of 600 and 700-class helicopters, where its immense torque can effortlessly handle the extreme loads of aggressive 3D aerobatics. The DS610's powerful coreless motor and robust titanium alloy gear train deliver a massive amount of power with a smooth and precise feel, giving the pilot a confident and connected sense of control over their machine. The servo's high-resolution digital controller ensures that it centers with precision and holds its position with unwavering stability, even under the most demanding of loads. The aluminum mid-case acts as a heat sink, ensuring that this high level of performance is maintained throughout the flight.
- The DS610's exceptional performance is no coincidence; it is a testament to its high-quality design, which is known in the hobby to be a rebranded version of the renowned Savöx SC-1258TG. This shared heritage is a mark of its quality and a reason for its enduring popularity among discerning pilots. While it is a dominant force in the helicopter world, the DS610's impressive power and precision also make it an excellent choice for a variety of other demanding applications, such as the steering of 1/8 scale buggies and truggies, or the control surfaces of giant-scale aerobatic aircraft. The Align DS610 is a true icon in the world of RC servos, a component that can be trusted to deliver uncompromising performance and reliability.

Application(s): Tail rotor servo for Align T-Rex 450 Pro FBL
Comments: Have 230 flights on it in my 450, so far without problems. It holds the tail very stable (I'm using an Align 3GX V3.0 as FBL controller). It has survived a number of bad crashes (did have to change gear set twice, but that's all). I have run it on 5.5V and 6V, it works well with both voltages.
