Notes
- The discontinued Hyperion DS20-FMD is a high-performance digital servo in a standard-size, low-profile "wing servo" configuration. Its model name breaks down its impressive feature set: a standard-size footprint but low profile ("20"), a Fast-winding motor ("F"), a durable all-Metal gear train ("M"), and a precise Dual ball-bearing supported output ("D"). This servo is a powerhouse, designed for the wings of large, high-performance sailplanes, giant-scale aerobatic aircraft, and jets. Its low-profile design allows it to be installed in relatively thin wing structures, while its fast motor and strong metal gears provide the performance needed for these demanding aircraft.
- The defining characteristic of the DS20-FMD is its ability to deliver high-speed, high-power performance from a sleek, low-profile case. When mounted in the wing of a giant-scale aerobatic plane, it has the speed for a blistering roll rate and the strength to move large ailerons with precision, even during violent maneuvers. In a large sailplane, it can actuate large flaps quickly and reliably for landing control.
- For roboticists building large-scale projects, the DS20-FMD is an exceptional actuator. Its low-profile design and high power make it perfect for applications where a standard-sized servo is too tall or bulky. It would be an excellent choice for the joints of a large but slim robotic arm, for a powerful steering system on a low-slung autonomous rover, or for any mechanism that requires high torque and speed to be delivered from a confined space.
