3-6S G4 XDFly 85A SBEC 32 Bit ESC For 380-420 RC Helicopter EDF
The XDFly HPRO 85A SBEC is a premium 32-bit G4 (170MHz) ESC delivering 85A continuous and 160A burst on 3-6S LiPo. At 70×36×21mm and 93g with 6-12V/10A adjustable BEC, multi-protocol telemetry, governor mode, and XT60 for 380-420 helis and high-power fixed-wing.
XDFly HPRO 85A SBEC 32-Bit G4 ESC 3-6S with 6-12V BEC for 380-420 RC Helicopter, EDF and Fixed-Wing 3D
85A/160A for 420 Helis & High-Power Fixed-Wing
The HPRO 85A delivers 85A continuous and 160A burst — substantial headroom over the 130A burst typical of this class — using new-generation MOSFETs that run cooler and handle instantaneous current spikes with ease. Ideal for 380-420 helis, .70-class fixed-wing 3D, and 75mm EDF jets.
Lighter Than Comparable ESCs
At just 93g and 70×36×21mm, the HPRO 85A is significantly lighter than same-class competitors (typically 105-110g), reducing all-up weight on aerobatic airframes where every gram affects flight performance.
32-Bit G4 Precision
The 170MHz G4 processor delivers efficient processing and accurate motor output, with smooth startup and linear throttle response that pilots can feel in both heli collective management and fixed-wing 3D sequences.
6-12V Wide-Range SBEC
The 6-12V adjustable SBEC (10A continuous, 0.2V steps) powers HV servos and gyro/flybarless controllers directly, eliminating the weight and complexity of an external BEC.
Vented Case for Superior Cooling
The unique HPRO housing with side air vents and optimized internal airflow increases heat dissipation area, keeping MOSFET temperatures low during sustained high-power aerobatics.
XT60 & 3.5mm Bullets Pre-Installed
Amass XT60 battery connector and 3.5mm gold bullets come pre-soldered for fast, reliable installation.
Full Telemetry Ecosystem & Protections
Telemetry for VBar VBCt/E, Rotorflight2, SBUS2, Jeti, Brain, and iKon. APP/LCD G2 programming, firmware upgrades, heli governor, fixed-wing mode, ARTime autorotation restart, self-check, and seven protection layers.
