FrSky Xact M5252H Micro Digital HV Coreless Servo
The FrSky Xact M5252H is a compact, high-voltage digital servo that combines strong torque with fast response. At 8.4V, it delivers up to 177.8 oz-in (12.8 kg-cm) of torque with a quick 0.05 sec/60° transit time.
Designed for demanding RC aircraft installations, the M5252H features a responsive coreless motor, durable metal gears, dual precision ball bearings, and a Hall-effect position sensor. Its fully CNC-machined aluminum case provides added strength and heat dissipation while maintaining a compact micro-servo footprint.
The M5252H supports conventional PWM operation along with SBUS and F.Port 2.0/FBUS. When connected to compatible FrSky equipment, FBUS allows servo telemetry data such as current, voltage, and temperature to be returned to the transmitter. Servo travel and other supported settings can also be configured through compatible FrSky tools.
