I have a pixhawk fc and a turnigy 9x with a PPM encoder.....my problem is i am unable to get the 3 position switch to work.........works fine with my APM builds.....i am currently using my Cheerson cx-20 TX/RX and it works fine on the pixhawk....all flight modes work....but no luck with the Turnigy 9x and Pixhawk....i do not want to have to use a separate TX/RX on apm and pix both...can anyone please help?

I have followed this diagram exactly....i even have the same receiver and ppm encoder
