Since doing the reviews on a few 2S whoops with the SPI based receivers I was asked several times if they would work with an LBT radio. My answer to that was "I think so" based on being able to get D8 mode back into the OpenTX firmware and the SPI having what is effectively a D8 mode. I didn't like being quite so vague though, so I decided to flash one of my radios and see for myself.
You can find the latest version of OpenTX Companion (at the time I making this video) here https://www.open-tx.org/2019/01/06/opentx-2.2.3 but if in any doubt, check https://www.open-tx.org and follow the link to the latest release to find out if it is the latest. The software checks for its own updates anyway so should keep itself updated to the latest code.
