Purchased this R9M module and R9MM OTA receiver to convert to express LRS long-range, as the Happymodel modules and receivers were out of stock at the time. I followed the instructions from Bardwell on YouTube, and managed to set up all fine. Well packaged, received a great working order and in good time from Banggood.

Good module and receiver if you know how to get it working. There are many firmware versions and they are all very confusing. Note that OTA firmware updates are only possible when using the ACCESS firmware. However, ACCESS firmware is not compatible with most older transmitters because it requires an additional serial connection to the JR module bay E.g. the Jumper T16 Pro does not work with ACCESS, so ACCST firmware is required. This version of firmware is not as well supported by Frsky as ACCESS, but it does work, less the OTA feature.
