HobbyWing ESCs v3/v4 are equipped with RPM lead that is providing signal for the external governor. So you do not need to do anything else except connect the cables properly and turn off the internal Governor of the ESC.


1 Required modification

For usage with the Spirit units a small modification of the RPM cable is needed.

  • Move the Yellow cable to the middle in the Servo connector.
  • You can do so with a needle easily.


Wire layout
Yellow wire: RPM Output Signal (PIT pin)
White wire: Throttle signal (AUX1 port)
Red wire: BEC Voltage (AUX1 port)
Black wire: Ground (AUX1 port)


Connect the cables according the photo now.

2 Changing ESC mode

It is very important to change ESC mode so that internal Governor is disabled.

This can be made by a Multifunction LCD Program Box. Please see HobbyWing manual.

You can use the following modes:

  • Helicopter (Linear Throttle) - great for beginners.
  • Fixed-wing - great for advanced (will eliminate problems with slow spoolup and Autorotation Bailout feature).

After this, you can enable Governor in the Spirit unit.

3 Governor Settings

In the Spirit Settings open the General - Throttle/Governor window and set the following:

  • Throttle Frequency: 120Hz.
  • Throttle Range - Min.: 1100 us.
  • Throttle Range - Max.: 1940 us.
