I finally got a micro SD card to work. It's brand name SanDisk Ultra microSDHC UHS-I card with adapter! 16GB Speed up to 80MB/s..... Don't get the 100 speed it does not work. On the back of the card it says it is for Fire Tablets and Fire TV.
I hope this helps other people.
The transfer was so easy after having right card .
Editing the models and the menus are so easy to use. I like this transmitter. Futaba did a great job on it!
