Notes
- The discontinued Align DS420 is a specialized digital micro servo engineered to provide lightning-fast response times for the demanding tail rotor control of 250 and 450-class helicopters. Its design is singularly focused on speed, a critical attribute for counteracting the torque of the main rotor and providing a locked-in, consistent tail hold. The DS420's high-speed digital controller and responsive motor work in perfect harmony with modern heading-hold gyros and flybarless systems, ensuring that every command is executed with immediate and precise movements. This rapid response is essential for crisp tail stops, precise piroetting maneuvers, and the overall stability of the helicopter. The servo's aluminum mid-case acts as a heat sink, ensuring that this high level of performance is maintained throughout the flight.
- The DS420's performance is further enhanced by its durable, high-strength gear train, which is designed to handle the high-frequency movements of tail rotor control. While its torque output may be modest compared to a cyclic servo, its speed is its greatest asset. For the pilot who is looking for a dedicated tail servo that can keep up with the most demanding of 3D maneuvers, the Align DS420 is the perfect choice. It is a specialized tool that excels in its intended role, providing the speed and precision needed to unlock the full aerobatic potential of any 250 or 450-size helicopter.
