HPRO XDFly 155A SBEC G4 3-8S ESC With RGB F3C And 2m F3A Fixed Wing ESC
The XDFly HPRO 155A SBEC is a premium 32-bit G4 (170MHz) ESC delivering 155A continuous and 260A burst on 3-8S LiPo. At 90×43×25mm and 158g with 6-12V/10A BEC, RGB LED, temp-controlled fan, multi-protocol telemetry, and governor for 550-580 helis and F3C/F3A fixed-wing.

260A Burst — Flagship SBEC for 550-580 & F3C
The HPRO 155A is the most powerful non-HV ESC in the HPRO lineup, delivering 155A continuous and a massive 260A burst — over 50% more burst current than the 170A typical of this class. Built for 550-580 helicopters, F3C competition, and 2m F3A fixed-wing aircraft where precision and power headroom are non-negotiable.
Same Footprint as 125A, More Burst
Shares the identical 90×43×25mm (no fan) housing and 158g weight as the 125A, making it a direct drop-in power upgrade for existing 550-class airframes — no mechanical reconfiguration needed.
3-8S Voltage, 6-12V SBEC
Wide 3-8S input covers 6S to 8S setups. The 6-12V adjustable SBEC (10A, 0.2V steps) directly powers high-voltage cyclic, tail, and throttle servos plus flybarless controllers.
G4 Processor for Competition Precision
The 170MHz G4 MCU with adjustable governor P/I gains maintains rock-solid rotor RPM under varying load — essential for F3C precision maneuvers and F3A aerobatic sequences where constant speed is scored.
Temp-Controlled Fan & RGB LED
Smart fan activates above 40°C for silent ground operation and active in-flight cooling. Multi-color RGB LED provides at-a-glance status and fault indication with user-selectable colors.
Vented Premium Case
The unique side-vented housing maximizes heat dissipation area while keeping weight at 158g — lighter than competing 150-160A ESCs.
Full Telemetry, Programming & Protections
VBar VBCt/E, Rotorflight2, SBUS2, Jeti, Brain, iKon. APP/LCD G2 programming, firmware upgrades, governor, fixed-wing mode, ARTime autorotation restart, power-on self-check, and seven protection layers.
