FrSky Xact M5253H Micro Digital HV Coreless Servo
The FrSky Xact M5253H is a compact, high-voltage digital servo delivering up to 141.5 oz-in of torque with a fast 0.07-second transit time at 8.4V. Its micro-size aluminum case makes it an excellent choice for RC aircraft installations where space and weight are limited but dependable torque and precise control are still required.
The M5253H combines a responsive coreless motor, metal gears, dual precision ball bearings, and a Hall-effect position sensor. It supports conventional PWM operation along with SBUS and F.Port 2.0/FBUS connectivity.
When connected to a compatible FrSky FBUS receiver or flight controller, the servo can return telemetry information such as current, voltage, and temperature. Servo travel and other supported settings can be configured through compatible FrSky tools.
