Hobbywing Xrotor Micro 4in1 40a ESC

$39.99 $59.99
  • Brand: Hobbywing
  • Product Code: HWG-XRTR-40A
  • QTY Remaining: 1

The Hobbywing Xrotor Micro 4in1 40a ESC uses the BLHeli-S A-H-50 16.5 firmware. This 4in1 ESC is compatible with all flight controllers, as well as the Hobbywing XRrotor F4, without soldering.


  • The ESC firmware uses hardware generated motor pwm for smooth throttle response and silent operation. Damped light does regenerative braking.
  • DShot150/300/600 Ready
  • Besides the regular PWM mode, Oneshot 125/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.
  • 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).
  • The use of EMF8BB21F16G MCUs with the operating frequency of up to 48 MHz, 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 a more rapid response. The 4-in-1 ESC not only includes 4 high-performance 40A ESCs and 1 built-in BEC, but also an Amp/Volt monitoring port, which allows the FC to monitor the voltage & amperage in real time (on condition that the FC supports this function); it's as small as most 30x30 flight controllers, which makes for easy installation and wiring. With the remarkably small size, it's a perfect match for competition FPV racers.
