Newbie here!Trying to get my Frsky R9 rx to work with my F405 fc in setting up a fixed wing.Not successful so far.
My rx has the following connections,ground,power,fport,sbus in and sbus out.
In addition to power and ground,which connections should I make?
My tx offers me the option of selecting sbus or fport for telemetry.Which should I select?
Thks
