Mission Planner SITL FRSKY Horus RC compability

Hello,

I have an issue with my RC input in SITL.
The inputs of my RC-transmitter isn’t recognized during my simulation with X-Plane 11.
I’m using the FRSKY Horus transmitter, does anyone has any experience with this setup or in general tried the combination Mission Planner SITL + Xplane + FRSKY transmitter?

Thanks in advance
