FrSky ACCESS 900MHz long range R9 MM-OTA receiver

Product Review (submitted on August 8, 2020):
I bought the R9 system to replace my old 2.4 receivers. I'm pleased with the small size and extended range. I'm also especially happy that I can still get these R9MM with un-inverted data port and compatibility with my existing FRSKY ACCST transmitters. Even though you cant use the new OTA feature, flashing the firmware by wire is still easy and well documented. Thank you.
