XDFly ESC HPRO 35A SBEC G4 3S-6S 6V-12V BEC 250-300 RC Helicopter ESC

XDFly HPRO 35A SBEC 32-Bit G4 ESC 3-6S with 6-12V Adjustable BEC for 250-300 RC Helicopter and Fixed-Wing Aircraft

Premium G4 Power for 250-300 Helis & Small Fixed-Wing

The HPRO 35A is the entry point into XDFly's high-end HPRO lineup, built around a 32-bit G4 processor running at 170MHz. It delivers class-leading processing speed and throttle precision in a 42g package designed for 250-300 class helicopters and small sport/aerobatic fixed-wing aircraft.

35A Continuous / 55A Burst on 3-6S

New-generation power MOSFETs provide low heat generation, high instantaneous current handling, and high reliability — 55A burst handles collective pitch changes and aerobatic maneuvers with confidence.

6-12V Wide-Range Adjustable SBEC

The 6-12V adjustable SBEC (8A continuous, 15A peak) outputs in 0.2V steps — far wider than conventional 6/7.4/8.4V BECs — directly powering HV servos and receivers without an external BEC.

Unique High-Dissipation Case Design

The distinctive housing with side vents and optimized airflow greatly increases heat dissipation area, keeping the ESC cool during extended 3D flights while remaining compact at 48×25×16mm.

Multi-Protocol Telemetry & Programming

Compatible with Mikado VBar VBCt/E, Rotorflight2, Futaba SBUS2, Jeti, MSH Brain, and iKon telemetry ecosystems. Program via XDFly APP, LCD Program Card G1, or directly through supported transmitters.

Governor & Fixed-Wing Modes

Dedicated helicopter governor with adjustable sensitivity plus a fixed-wing mode for sport and aerobatic airplanes. Autorotation rollback (ARTime) allows quick motor restart within a set window to prevent crash landings.

Self-Check & Comprehensive Protections

Power-on self-check diagnoses short circuits, phase loss, throttle zero, and voltage anomalies. Seven protection layers: voltage anomaly, startup, temperature, signal loss, overload, low-voltage, and over-current.
