Generation 2

  • Redesign every aspect
    STM32 F405 MCU
     allows the FC to run the PID looptime and gyro with higher frequency.
  • The SPI ICM-20602 which integrates accelerometer and gyro (with the running frequency can be set to 32KHz) is adopted.
  • Onboard OSD microchip which supports the DMA mode allows users to adjust its parameters via the Betaflight software. (Note: the OSD is controlled by the F4 MCU.)
  • The FC which supports Betaflight firmware & allows parameter adjustment via Betaflight software is more applicable to FPV race.
  • F-card which can record and save more flight/black box data allows users to adjust thesetup of their aircraft easily.
  • Compatible with various receivers like SBUS, SUMH, SUMD, SPEKTRUM1024/2048, XBUS, PPM and etc.
  • LED strip signal output port allows users to adjust the color & flash mode of the LED strip via the FC.
  • Volt/Amp monitoring port allows users to check the battery voltage (BAT port) and current (CRT port , extra current meter is needed).
  • Buzzer output port allows users to connect external buzzer(s) to the FC for warning or informing the flight status of the aircraft.
  • Micro USB port allows users to connect the FC to a PC to flash firmware and adjust parameters.

Please ensure that you’ll solder the capacitor included in the box onto the ESC when soldering input wires, otherwise, failing to do so ESC will get burnt/damaged. see IMPORTANT NOTES below

  • HOBBYWING products purchased from Hong Kong / Chinese retailers do not confirm CE / North America regulation - deems products non-warranty

  • Discount /auction stores such as eBay, Banggood,  are considered "non-authorized sales channel" in North America. Products deem non-warranty


HOBBYWING engineering and production staff will continue to review the Xrotor 45amp 4-1 ESC as crucial and important part of our drone racing and freestyle line up. Thus far, it appears that failures outside the normal have some basic usage trends that could be related to the precautions mentioned below.

For all applications, please note the following.
1. Power capacitor must be installed.  Every Xrotor 45amp 4-1 includes 2 power capacitors. One larger, and one smaller.   The larger capacitor should be used for 5s-6s lipo, the smaller capacitor can be used for 4s-5s lipo.  Failure to use the included power capacitors will result in damage to your ESC.

2. BL_Heli_32 ESC settings can cause damage. Default settings should be used.

3. Motor KV ratings and prop size/pitch combinations recommendations.

- 4s Lipo using 5 inch props up to 2700KV
- 5s using 5 inch props, up to 2450 KV
- 6s using 5 inch props up to 1750 KV
