The FrSky Xact MD5301H Coreless MIDI HV Servo is engineered for pilots demanding exceptional torque, ultra-fast response and absolute reliability. Featuring a powerful coreless motor, hardened metal gears and a fully CNC-machined aluminium case, the MD5301H is ideal for high-performance RC aircraft, helicopters, jets and large-scale models.

Designed for operation up to 8.4V, the MD5301H delivers an impressive 27kg.cm of torque while maintaining lightning-fast transit speeds of just 0.06 sec/60°. The integrated Hall sensor and dual precision ball bearings provide outstanding centring accuracy, smooth movement and long-term durability.

Supporting FrSky's advanced FBUS (Port 2.0) protocol alongside SBUS and PWM operation, the servo can transmit real-time telemetry data including voltage, current consumption and temperature when connected to compatible FrSky receivers or flight controllers.

Servo travel can be configured to 90°, 120° or 180° through the FrSky ETHOS Xact Configuration Tool or Freelink App, providing maximum flexibility for a wide variety of model applications.
