XDFly HPro 155A ESC (3–8S, SBEC) – 550–580 Class
The XDFly HPro 155A is a high-performance brushless ESC designed for 550–580 class helicopters and demanding fixed-wing aircraft. Supporting 3–8S LiPo systems, it integrates an adjustable SBEC (6–12V), advanced cooling, telemetry support, and multi-color LED indicators. With strong current handling, governor mode, and built-in protections, it delivers precision and reliability for serious RC pilots.
Key Features
- High-performance 32-bit G4 processor running up to 170 MHz for precise control.
- Next-generation MOSFETs ensure low heat, strong burst capacity, and high reliability.
- Automatic startup self-check: monitors for shorts, motor phase loss, throttle zero, and voltage range.
- Unique case design with expanded heatsink surface for superior heat dissipation.
- Smart cooling fan activates only above 40 °C, keeping setup and flight quieter.
- Helicopter governor function maintains constant rotor RPM with adjustable sensitivity.
- Adjustable stall-landing timer to help avoid crashes from pilot error.
- 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) for clear status indication.
- Comprehensive protections: voltage, startup faults, over-temperature, signal loss, overload, low-voltage, and over-current.
