After initial troubles with the Frsky firmware having glitches, the module and later firmware are functioning flawlessly
Not fully Access Compatible
I bought this because I was told by Frsky that I would be able to use Access with my R9M module with the up grade. I did the install and updated all the firmware and the Access firmware is not working with the my module in my Horus 10. So if you are happy to just have the Access for X series rx then you are good to go. Other then that you will need to buy a whole new radio.
