The EMAX ES9055II is a heavy-duty, high-voltage all-metal digital servo engineered for demanding heli tail, fixed-wing control surface, robotic joint, and automation applications. Built around a contactless magnetic encoder, the ES9055II delivers drift-free centering under sustained vibration with up to 35 kgf·cm of stall torque at 8.4V. Configurable for 180° or full 360° positional control, with a standard JR connector and 23T spline for drop-in compatibility with existing installations.
