Tips:
- To enable blackbox recording, go into the CLI tab in Betaflight and type the following command:
set blackbox_device = SPIFLASH
set flash_spi_bus = 2
resource FLASH_CS 1 a14
save
- To bind the receiver, make sure your TX is updated to the V3.X version. The binding procedure is the same as the EP1/EP2 (3 consecutive USB plug in to put the receiver into bind mode or via passphrase - if you're having difficulties there is an alternative way of binding here)
- Note that Model match is on by default. You can turn that feature off by connecting the ELRS rx to the ELRS page, then go to the "model" page and turn model match off
