1. Make sure the transmitter system has been updated to version 1.4.0 and above.

Take the FrSky X20S transmitter as an example:



2. Turn off the transmitter, press and hold the [Confirm Button] and the [Power Button] at the same time to enter the 【Bootloader 】interface, and after the computer recognizes the TF card memory disk of the transmitter, double-click to open it, as shown in the figure below:



2-1: If you are using a transmitter with built-in storage (such as X18/X18S/X20R), the memory disk name will be displayed as RADIO or NAND, as shown in the image below:


Note: For users of transmitters with built-in memory disks like the X18/X18S/X20R, who want to use a TF card, the disk name will be displayed as in Step 2. You can then select the storage location in the transmitter under 【General Settings -- Storage Location】


3. Find the 【bitmaps】 folder in the memory disk and open it.



4. Find the 【Models】 folder. If not, you can re-create it yourself.

5. Open the 【Models】 folder and put in the picture of the DIY model image you made.



The image requirements are as follows:

①Choose BMP or PNG format based on your needs.

   Note: The difference is that PNG format requires 4 bytes per pixel to store its color information and supports transparency, while BMP format only requires 3 bytes but no color richness for a smaller file size.   

②The file name, including the extension, should be no more than 15 bytes.

③The resolution of the image cannot exceed the resolution of the transmitter screen.

④The larger the image memory size, the more laggy it will display on the transmitter; conversely, smaller images will display more smoothly.

6. Once the image import is complete, power on the transmitter, go to 【Model Menu -- Edit Model -- Image】, and you will see the DIY model image.



7. If the image cannot be displayed, you can use the ETHOS SUITE software -- 【Image Manager】 to convert the format.

Put the converted image back into the Models folder, then go to 【Edit Model -- Image】to view it.
