Get rid of Jello with the Tarot T-2D gimbal

Have you noticed Jello in your video while using the Tarot T-2D gimbal. Here the Jello is not coming from vibrations due to the motors or props, but the gimbal itself. Even with IRIS on the ground and motors turned off, you can sometimes see the vibrations of the camera and the resulting Jello in the video footage. In this article I will show you how to fix this.

Required materials and tools

The following materials are required.

  • The USB dongle and cable that came with your Tarot T-2D Gimbal
  • A charged battery for your IRIS

The following tools are required:

  • None

How-to assemble

Follow these steps to change the configuration of the Gimbal motor settings:

  • (Optional) It is highly recommended to upgrade the Gimbal software to the latest version.
  • Use the provided USB dongle to connect the Gimbal board to your computer (Windows only). You have to connect to the motor driver connector (See below).

  • Download and unzip the Tarot Gimbal Firmware v1.5 zip file to a convenient place on your computer.
  • Double click on the ZYX-BMGC-EN_V1.5.exe file (found in the above zip) and the configuration UI shown below should appear.

  • Click on the Motor Configuration button in the lower center of the screen and the configuration UI shown below should appear.

  • Power the Gimbal by plugging in the battery of your IRIS.
  • In the configuration UI, select the COM port and press the “Open COM Port” button.  After a few seconds you should see the values for Rolling Motor and Tilting Motor to be updated.
  • Change the value for Tilting motor -> Power to the value 25.
  • Save the settings to the Tarot gimbal by clicking on Write Settings to Flash.
  • You can now disconnect the USB dongle and power cycle IRIS.


As a result vibrations of the Tarot Gimbal should stop and the Jello from your video footage should be gone.
