XDFly HPro 125A SBEC ESC 3–8S (500–550 Class Helicopters)

XDFly HPro 125A ESC (3–8S, SBEC) – 500–550 Class

The XDFly HPro 125A is a high-performance brushless ESC engineered for 500–550 class helicopters and large fixed-wing aircraft. Supporting 3–8S LiPo power systems, it integrates an adjustable SBEC (6–12V), advanced cooling, telemetry support, and LED indicators. With robust current handling and safety features, it delivers reliability and precision for demanding RC pilots.

Key Features

• 32-bit G4 processor running up to 170 MHz for ultra-fast response and smooth control.
• Next-generation MOSFETs provide reduced heat, high burst endurance, and increased reliability.
• Startup self-check detects shorts, motor phase loss, throttle zero, and voltage anomalies.
• Unique heatsink case design expands surface area for superior heat dissipation.
• Smart cooling fan automatically engages above 40 °C, keeping noise low during setup and flight.
• Helicopter governor maintains constant rotor RPM with adjustable sensitivity.
• Adjustable stall-landing timer helps prevent crashes from handling errors.
• Independent programming via XDFly Android/iOS App, Mikado VBCt/e, RotorFlight 2, and Jeti.
• Telemetry support for VBCt/e, RotorFlight 2, Futaba S.Bus2, Jeti, MSH Brain, and iKon.
• Five selectable LED colors (red, green, blue, yellow, white) provide clear ESC status feedback.
• Comprehensive protection against abnormal voltage, startup faults, over-temperature, signal loss, overload, low-voltage, and over-current.
