Frsky TD MX receiver telemetry possibilities?

As I,am building a ranger 1600 with speedybee f405 wing mini some question came on my path.
I intend to use as receiver the frsky TD MX reason because its double frequency band use and the sbus for servo,s.
The fbus/port for telemetry?
My question will this work?
Not quit clear for me the term fbus .
Ardupilot must be connected with the rx and tx so telemetry some where some howe ???
Have someone experience with this?
Like to hear.
Up until now a steep learning curve so i,am convident to succeed.
Kind regards, Theo
