HOBBYWING XRotor Micro 40A 4in1 ESC 30901076 - Compact FPV Race Unit  [HW-30901076]

High performance 4-in-1 ESC for tight FPV builds

The Hobbywing XRotor Micro 40A 4in1 ESC is a compact electronic speed controller engineered for FPV pilots who want reliable power in small frames. It combines four 40A ESC channels, an integrated BEC, and an amp/volt telemetry port to suit lightweight racing and freestyle machines where space is at a premium.

Fast switching and thermal efficiency

Using EMF8BB21F16G MCUs up to 48MHz and high-grade MOSFETs with ceramic capacitors, this ESC is tuned to keep loss and heat to a minimum. The six-layer PCB with 3-ounce copper traces supports rapid current flow and consistent behaviour under aggressive throttle demands.

BLHeli-S firmware with modern digital protocols

This XRotor Micro 4in1 arrives with BLHeli-S firmware and allows firmware updates via the throttle signal line or a supported flight controller. DShot150/300/600 compatibility cuts signal jitter and delivers quicker motor response for precise stick inputs.

Smooth throttle shaping and braking control

Hardware PWM ensures smooth throttle transitions and reduced motor noise. The damped light mode provides effective regenerative braking for tighter deceleration and enhanced control during fast passes or landings.

Built for pilots who need compact power and precise control, the Hobbywing XRotor Micro 40A 4in1 ESC fits 130-280mm FPV frames for racing and freestyle duty.
