Programming a coax copter firmware in mission planner

Hi everyone, please assist/provide guidance with with the installing of coax copter firm in my pixhawk… The radio calibration failed due to me using FS-I6X RC, not appearing on mission planner (beginner).

a) Have you paired your receiver to your transmitter?
b) Do you have your receiver powered ? (Many FC’s don’t have power applied to input ports)
c) If in doubt just connect a servo directly to your receiver + power and see if it works / responds to your transmitter.

Thank you I sorted it out, by connecting the receiver in the PPM encoder port… I am still in the wiring process so, wish me luck…
