HobbyWing - RC Speed Controllers ESCS
PDF icon Manual379.88 KB

Hobbywing have a reputation for making some of the best quality RC gear on the market, and this latest offering from them is no exception.

The Hobbywing XRotor Micro 40A 4-in-1 BLHeli_S equipped ESC is a high power output, incredibly capable, and compact ESC. Featuring high-performance 40A ESC's (50A Burst), support for up to 5S LiPo, a 5V 1.5A BEC and a Amp/Volt Monitor port for compatible Flight Controllers. The Xrotor 40A will surely be one of the premier choices for racers looking for nothing but the best in regards to performance.

The XRotor 4-in-1 ESC is designed to stack with Hobbywing's F4 flight controller, making for a very neat and easy installation.


  • Compact design for easy installation and neat wiring.
  • Amp/Volt monitoring port allows flight controller to monitor the voltage & amperage in real time (on condition that the Fc supports the function).
  • EMF8BB2 chip with an operating frequency of 48MHz for great performance.
  • Top mosfet, 3 in 1 IC driver, imported high quality ceramic capacitors.
  • BLHeli-S open source program supports firmware update or ESC programming via throttle signal wire and all the functions of BLHeli-S.
  • Damped light mode for rapider motor response.
  • Regular PWM throttle mode, OneShot125 throttle mode, OneShot42 throttle mode, and MultiShot throttle mode are supported.
  • Dshot1250/300/600 digital throttle mode is support.
  • ESC supports a throttle signal of up to 621Hz in regular throttle mode and is compatible with various flight controllers.
  • Active freewheeling technology, recovery of electricity to extend battery life.

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.
