From Google Translate:
"I can't find FrSky V8FR - II receivers anywhere, does anyone know if there are any alternatives for FrSky V8FR - Il that I can also use, would be very grateful!"
The V8FR-II receivers are quite old in the FrSky lineup. I would check eBay or other sites for people selling used models if that's really what you're after. What transmitter do you have? If you can move up to the D16 protocols you can use the newer (not the newest) ACCST models like the X6R, X8R, S6R, S8R, etc.
