Notes
- The discontinued Blue Arrow D50013 is a colossal, large-scale digital servo, engineered for applications where sheer, unadulterated power is the primary requirement. This servo operates in a class of its own, designed to command the enormous control surfaces found on giant-scale aircraft, typically those of 25% scale and larger. On a 35% scale aerobatic airplane, the rudder alone can be several square feet in area. The D50013 provides the immense torque needed to move such a surface with speed and precision, even during violent, high-G maneuvers like waterfalls and knife-edge spins. It is also a top choice for the primary flight controls on large jet turbine models, where high speeds and massive aerodynamic forces demand a control system with absolute authority and zero chance of failure.
- The key feature of the D50013 is its raw, overwhelming power output, backed by the precision and holding ability of a sophisticated digital controller. Its internal components, from the motor to the gear train, are massively overbuilt to handle incredible loads and dissipate heat effectively. Pilots of giant-scale aircraft invest tens of thousands of dollars in their airframes and engines; they choose a servo like the D50013 because it offers the uncompromising reliability and performance needed to protect that investment. It provides a direct, solid, and unflinching connection to the aircraft, which is essential for safe and confident flying at this scale.
- In the realm of robotics and industrial automation, the D50013 is a beast. It is suitable for actuating major structural components, such as the primary joints on a large, human-sized robotic arm designed for heavy lifting. It could be used to operate heavy-duty industrial grippers, steer very large and heavy autonomous rovers, or even in animatronics to move the large limbs of a theme park creature. When a project requires moving a heavy load with precision, the D50013 is the actuator for the job.
