Lightweight 4in1 Racer - Hobbywing 30901068 - XRotor Nano 20A 4in1 ESC for FPV Drones  [HW-30901068]

Small Footprint Power for Mini FPV Builds

The Hobbywing XRotor Nano 20A 4in1 ESC packs four reliable 20A speed controllers into a tiny package aimed at indoor and tight-frame FPV quads. Its consolidated design reduces wiring and makes installation straightforward when paired with the XRotor Nano flight controller, saving space in compact stacks.

Core Components That Reduce Heat and Latency

The unit uses an EMF8BB21F16G MCU running up to 48MHz alongside imported MOSFETs, integrated 3-in-1 drive ICs, ceramic capacitors, and a six-layer PCB. These parts combine to lower thermal load, boost efficiency, and produce quicker motor response for agile flying.

BLHeli-S Ready with Modern Protocol Support

Shipped with BLHeli-S firmware, the ESC supports parameter tuning and firmware updates via the throttle signal or through a flight controller running Cleanflight or Betaflight. Protocols include PWM, Oneshot125, Oneshot42, Multishot, and DShot150/300/600 for cleaner signals and faster commands.

Refined PWM and Motor Damping

Hardware-generated PWM yields smooth throttle curves and quieter operation. The damped light mode gives regenerative braking and quicker motor slowdown, improving control during tight maneuvers and short indoor flights.

This Hobbywing XRotor Nano 20A 4in1 ESC is ideal for pilots wanting compact efficiency and fast ESC response in small FPV rigs.
