Availability: In stock


The latest high performance ESCs from Hobbywing. The Hobbywing XRotor Micro 4in1 40A ESC for brushless motors is a 4in1 esc with standard 30.5x30.5mm mounting and offers a continuous rating of 40A and supports bursts of upto 50A. The firmware is BLHeli_S supporting DSHOT 600.


Highly Integrated & Compact
The 4-in-1 ESC not only includes 4 high-performance 40A ESCs, 1 built-in BEC, but also an Amp/Volt monitoring port which allows FC to monitor the volt & amp in real time (on condition that the FC supports this function); it’s as small as a FC for FPV(s) and easy for installation and wiring. With the remarkably small size, it's a perfect match for competition FPV(s).

High-quality Components
The use of EMF8BB21F16G MCUs with the operating frequency of up to 48MHz, imported high quality MOSFETs, 3-in-1 drive ICs and ceramic capacitors, 3-ounce copper, and 6 layers of PCBs guarantees less heat, higher efficiency and rapider response.

BLHeli-S Firmware Ready
The ESC (with great performance and rich functions) uses the original BLHeli-S firmware and supports adjusting parameters or upgrading firmware via different methods (i.e. via throttle signal wire with using other development board or a FC flashed with the Cleanfight / Betaflight firmware).

DShot150/300/600 Ready
Besides the regular PWM mode, Oneshot125/Oneshot42/Multishot modes, the latest DShot150/300/600 modes are also supported. In DShot150/300/600 modes, the ESC has great anti-interference performance and rapid response.

Hardware Generated PWM & Damped Light Mode
The ESC firmware uses hardware generated motor pwm for smooth throttle response and silent operation. Damped light does regenerative breaking, causing very fast motor retardation, and it inherently also does active freewheeling.
