Take Your Props Off
This quads can hurt you and in the right situations cause fatal injury. When dealing with motor direction and software involving your motors spinning, TAKE YOUR PROPS OFF. Do not be that guy who posts pictures on the internet of not taking your props off.
Blheli or Blheli_32?
If your’s support Blheli, it is usually indicated on the ESC or in your documentation. Blheli, Blheli-S, or Blheli_32.
There are two versions of the Blheli software. One is BLHeli_32 and BLHeli 16. BLHeli_32 is specifically for any esc with BLHeli_32. All other Blheli ESCs need to use the BLHeli16.
Download BLHeli or BLHeli_32
Both versions of the Blheli software can be found from the following link: https://drive.google.com/drive/folders/1Y1bUMnRRolmMD_lezL0FYd3aMBrNzCig [reference]. Download the version you need and install it. A windows based machine is required.
Open Blheli Suite
If your ESC is not Blheli_32 you are using the BlheliSuite16.
Run the BlheliSuite.exe

Before Connecting To Blheli
To connect to Blheli and change ESC settings, you need to connect your USB cable and power on your quad. Take your props off. Final warning.
Which Com Port?
Before you power up your quad and connect to Blheli, pay attention to what is in the port drop down in the lower left hand corner. In the example below, before we plug in we only have 3 options. COM1, COM15, COM16. These COM ports will vary from computer to computer.
What you need to pay attention to is when you power up your quad and connect it through the micro usb, an additional com port will populate the dropdown. This indicates which COM port BLHeli has identified your hardware on. In the example below, our new port is COM3. We will select it and use it to connect.
With the quad connected and powered up with the props off, click the connect button.
Click Read Setup
When the software has gathered information about your ESC’s it will prompt you with the following. Click Ok.
The software will read the first ESC and prompt you on its success or failure. Click OK.
