Sequre SQESC 28120 AM32 / BLHeli_32 120A ESC (2–8S, Adjustable BEC)

The Sequre SQESC 28120 is the “I’m done blowing ESCs” upgrade for anyone flying big multi-rotors, fixed-wing haulers, or RC models that could tow a small dog. Backed by a 32-bit STM32G071 processor, 120A continuous grunt, and 2–8S range, it’s the heavy-duty ESC you buy when your current setup wheezes under load. Keywords for the SEO overlords: 120A ESC, AM32 ESC, 8S brushless ESC.

Why You Want It

Because nothing kills a build vibe faster than heat-soak jitters or mystery desyncs. With its CNC metal radiator, chunky MOSFETs, and every protection mode short of “don’t fly into trees,” the SQESC 28120 stays cool, stable, and predictable. Bonus: the RGB LEDs let you cosplay as a DRL finalist. (Human-behind-keyboard note: yes, we know RGB adds 0 performance, but it’s fun.)

Disclaimer

Accessory bits may vary, but the ESC won’t magically downgrade itself to 30 A — we checked.

Still Here?

You’re either building something monstrous or procrastinating soldering. Either way, this 120A AM32/BLHeli_32 ESC with adjustable BEC voltage is ideal for high-load drones and RC builds that laugh at ordinary power systems. Treat yourself — or send this to a mate who insists “8S isn’t that much.”
