XDFly HPro 125A HV ESC (6–14S, SBEC) – F3C / 600–700 Class
The XDFly HPro 125A HV is a high-voltage ESC for F3C and 600–700 class helicopters, as well as large fixed-wing models. It supports 6–14S LiPo power and includes an adjustable SBEC (6–12V) for HV servos and FBL systems. With advanced processing, telemetry, smart cooling, and robust protections, it delivers smooth control and dependable performance for precision flying.
Key Features
- High-performance 32-bit G4 processor up to 170 MHz for precise throttle and governor control.
- Modern power MOSFETs for lower heat, strong burst endurance, and high reliability.
- Automatic power-on self-check: shorts, motor phase loss, throttle zero, and input voltage range.
- Thermally optimized case design increases heat-dissipation surface area.
- Temperature-controlled fan engages only above ~40 °C to keep noise down.
- Helicopter governor mode with adjustable constant-speed sensitivity for consistent head speed.
- Stall-landing timer (time-selection function) helps reduce crash risk from handling errors.
- Flexible programming via phone app (Android/iOS), Mikado VBCt/e, RotorFlight 2, and Jeti.
- Telemetry support: VBCt/e, RotorFlight 2, Futaba S.Bus2, Jeti, MSH Brain, and iKon.
- Multi-color LED status indicators (red/green/blue/yellow/white) with functional flash modes.
- Comprehensive protections: abnormal input voltage, startup faults, over-temperature, signal loss, overload, low-voltage, and over-current.
