Goosky RS4 Venom Combo 80A ESC Firmware Update for Rotorflight Telemetry

Goosky RS4 Venom Combo 80A ESC Firmware Update for Rotorflight Telemetry

This guide explains how to update the 80A ESC included with the Goosky RS4 Venom Combo to support Rotorflight telemetry. The update is performed on a Windows PC using the included HobbyWing USB Link software and a HobbyWing LCD Program Box.

Important: This firmware update is intended for the Goosky RS4 Venom Combo 80A ESC using the HobbyWing Platinum V5 Goosky firmware branch. Do not use this update on unrelated ESC models unless specifically instructed by Goosky, HobbyWing, or New England RC.
Firmware Selection Note: For Rotorflight telemetry, select PL-04.1.07-GS. Goosky has confirmed that PL-04.1.06-GS is for VBar telemetry, while PL-04.1.07-GS is HobbyWing telemetry and can be used with Rotorflight.
Do not disconnect anything during the update. Do not unplug the ESC, LCD Program Box, USB cable, or ESC power while the firmware update is running. Interrupting the update may corrupt the ESC firmware.

Inside the folder, run the application:

Hobbywing USB Link.exe

Step 2 — Connect the ESC and Programmer

  1. Connect the ESC programming port from the Goosky RS4 Venom Combo 80A ESC to the HobbyWing LCD Program Box.
  2. Connect the HobbyWing LCD Program Box USB-C port to your Windows PC or laptop.
  3. Power the ESC as required for the firmware update.
  4. Launch Hobbywing USB Link.exe.
Connection order: ESC programming port → HobbyWing LCD Program Box → USB-C cable → Windows PC.

Step 3 — Change the Software Language to English

When the HobbyWing USB Link software first opens, the top menu may appear in Chinese. Select the first menu on the top-left. This is the File menu. From the dropdown, select English.

Before — Chinese Menu


After — English Menu


Step 4 — Select Electronic Speed Controller

From the top menu, select:

Device(D) → Electronic Speed Controller

This tells the HobbyWing USB Link software that you are connecting to the ESC, not only the LCD Program Box.

Step 7 — Select and Install the Correct Firmware

On the Firmware Update screen, select the firmware version:

PL-04.1.07-GS

This is the HobbyWing telemetry firmware and is the correct version for Rotorflight telemetry support.

Do not select PL-04.1.06-GS for Rotorflight. PL-04.1.06-GS is the VBar telemetry firmware. For Rotorflight, use PL-04.1.07-GS.
  1. Confirm the Goosky RS4 Venom Combo 80A ESC is detected by the HobbyWing USB Link software.
  2. Select PL-04.1.07-GS.
  3. Start the firmware update.
  4. Wait until the software confirms the update is complete.
  5. Disconnect the ESC only after the update has fully finished.
Do not unplug anything while updating. Wait for the update to finish completely before removing ESC power or disconnecting USB.

After the Update

After the firmware update is complete, install the ESC back into the Goosky RS4 Venom and configure Rotorflight ESC telemetry as needed. The updated PL-04.1.07-GS firmware is required before Rotorflight can read supported HobbyWing telemetry from the Goosky RS4 Venom Combo 80A ESC.
