I just bought an FrSky Taranis for my quad copter and needed to get the Mavlink data up on the Taranis LCD telemetry display. So here is my solution using a Teensy3.1 as a converter between MavLink and the S.Port on FrSky X8R.

Artem & Andrew, what is the fw version on yours Taranis? just to compare...
mine is 2940

not at home so cannot reply right away, be back with info tonight.

please see the attached picture. I am in Toronto Canada
