Notes
- The discontinued Align DS510 is a high-performance digital 'mini' servo that has become a benchmark for the cyclic controls of 500-class helicopters. It offers a compelling blend of speed, torque, and precision that is perfectly suited for the demands of 3D aerobatics and sport flying. At its core is a powerful and efficient coreless motor, which provides a rapid and linear response to control inputs, resulting in a crisp and connected feel for the pilot. The DS510's digital controller processes signals with high resolution, ensuring that the servo centers precisely and holds its position with unwavering stability. The servo's aluminum mid-case not only provides a robust and durable structure but also acts as an effective heat sink, ensuring that performance remains consistent even during long and demanding flights.
- The DS510's composite alloy gear train is both strong and lightweight, providing a good balance of durability and performance. Its well-rounded performance characteristics have made it a favorite among 500-class helicopter pilots for its reliability and exceptional value. While it is primarily designed for helicopter cyclic applications, the DS510's impressive performance also makes it a suitable choice for a variety of other demanding applications, such as the control surfaces of large park flyers, electric gliders, and even the steering of 1/10 scale racing vehicles. The Align DS510 is a true workhorse of a servo, a component that can be trusted to deliver a high level of performance flight after flight.
