125A XDFly ESC 32 Bit G4 3-8S Temp Controlled Fan 500-550 RC Helicopter ESC
The XDFly HPRO 125A SBEC is a premium 32-bit G4 (170MHz) ESC delivering 125A continuous and 200A burst on 3-8S LiPo. At 90×43×25mm and 158g with 6-12V/10A BEC, RGB status LED, temp-controlled fan, multi-protocol telemetry, and governor for 500-550 helis and .90 fixed-wing.
XDFly HPRO 125A SBEC 32-Bit G4 ESC 3-8S with 6-12V BEC and Temp-Controlled Fan for 500-550 RC Helicopter and Fixed-Wing 3D
200A Burst for 500-550 Helis & Large 3D Fixed-Wing
The HPRO 125A delivers 125A continuous and 200A burst — far exceeding the 140A burst of same-class ESCs — using premium next-generation MOSFETs. Designed for 500-550 class helicopters and .70-.90 class fixed-wing 3D aircraft running 3-8S power systems.
3-8S Wide Voltage Range
Handles 3S through 8S LiPo in a single ESC, covering everything from 6S sport setups to 8S high-power aerobatic and EDF applications without needing a separate HV model.
Intelligent Temp-Controlled Fan
The integrated cooling fan activates automatically only above 40°C, providing active cooling during high-load flight while remaining silent during setup and low-power operation. Fan/no-fan dimensions: 90×43×36mm / 90×43×25mm.
RGB Status LED
Multi-color LED indicates ESC status and fault codes with selectable colors (red, blue, green, purple, white, and more) — both a functional diagnostic tool and a premium visual touch.
6-12V Adjustable SBEC
The wide-range 6-12V/10A SBEC (0.2V steps) powers HV servos and flybarless systems directly, with clean, stable voltage for critical flight controls.
32-Bit G4 & Vented Case
The 170MHz G4 processor and unique side-vented case with maximized dissipation area deliver cool, reliable performance under sustained 8S loads. At 158g, it is lighter than same-class competitors.
Complete Telemetry & Safety Suite
VBar VBCt/E, Rotorflight2, SBUS2, Jeti, Brain, iKon telemetry. APP/LCD G2 programming, firmware upgrades, governor with adjustable P/I gains, fixed-wing mode, ARTime restart, self-check, and seven protections including 110°C thermal throttling.
