HV SBEC XDFly 300A Anti Ignition 6-12V BEC 700-800 RC Heli ESC

XDFly HPRO 300A HV SBEC 32-Bit G4 ESC 6-14S with Anti-Ignition, 6-12V BEC for 700-800 RC Helicopter and Large-Scale Fixed-Wing

Flagship 300A/400A HV Power

The HPRO 300A HV is the flagship of the HPRO lineup, delivering 300A continuous and 400A burst on 6-14S LiPo — 25% more burst than the 320A typical of 300A HV ESCs. Built for 700-800 class helicopters and large-scale electric fixed-wing aircraft, including industrial and heavy-lift applications.

Anti-Ignition (Anti-Spark) Protection

A built-in anti-ignition circuit prevents dangerous sparking when connecting high-voltage 12-14S batteries, protecting connectors and electronics from inrush current — a critical safety feature on large HV setups.

6-12V/10A SBEC with 35A Peak

The wide-range 6-12V adjustable SBEC delivers 10A continuous and up to 35A peak, powering multiple high-torque HV servos on 700-800 helis and large aircraft without a separate BEC or receiver battery.

Premium MOSFETs, Low Heat, High Reliability

New-generation power MOSFETs deliver low heat generation and high instantaneous current handling, while the unique side-vented case with engineered airflow maximizes dissipation for sustained 14S operation.

Intelligent Fan & RGB LED

The temp-controlled fan activates above 40°C for quiet ground operation and active in-flight cooling. Multi-color RGB LED displays ESC status and fault codes with ten selectable colors.

G4 Processor & Cross-Platform Telemetry

The 170MHz G4 MCU with adjustable governor P/I gains maintains constant rotor RPM under extreme load. Native telemetry for VBar VBCt/E, Rotorflight2, Futaba SBUS2, Jeti, MSH Brain, and iKon.

Comprehensive Safety Suite

Power-on self-check, ARTime autorotation restart, synchronous rectification for efficiency, and seven protection layers: voltage anomaly, startup, 110°C thermal throttle, signal loss, overload, low-voltage landing reduction, and over-current.
