Good day!! Would like to know, are there compatilibility issues with the FC and the reciever? I have a Flysky Fs-i6s and an Fs-ia6b reciever… will it work on any PPm/ sbus capable FCs? Thanks guys!
The FS-ia6B can output ibus, so if your flight controller has a UART port that will work. It can also output PPM so if your flight controller supports PPM then that will work. If you read the manual it will tell you how to use PPM/SBUS with that receiver. 
Thank u very much! Availability is kinda scarce and kinda expensive here in my country… really carefull when buying… i think now i can move on!
