Notes
- The discontinued Graupner RBS581 is a state-of-the-art retract servo, likely featuring a powerful Brushless motor system as denoted by the "RBS" (Retract Brushless Servo) designation. This specialized, non-proportional actuator is designed for the most demanding landing gear systems on high-end, giant-scale aircraft. The brushless motor offers a massive advantage in a retract application, providing incredible power, efficiency, and a service life that is orders of magnitude longer than a conventional brushed motor. This ensures that the retract system will operate flawlessly for years without any degradation in performance.
- The core identity of the RBS581 is its ultimate, long-life reliability. A retract failure on a giant-scale jet or warbird can be disastrous. The brushless motor in this servo provides the ultimate peace of mind, as it is not prone to the wear and failure that can plague brushed motors over time. It delivers its powerful end-to-end action smoothly and consistently every time, making it the premier choice for the discerning scale modeler who is building a model to last a lifetime.
- For industrial automation, the Graupner RBS581 is a unique and incredibly valuable component. Its brushless motor makes it ideal for high-cycle, long-life binary actuation tasks, such as operating a safety latch on a piece of machinery that will be used millions of times. Its powerful, non-proportional action is perfect for any automated task that requires a simple, powerful, and incredibly reliable two-position actuator with a near-infinite service life.
