I dont think you need ppjoy for the FMS. I do think you need PICJOY, which can be found on toms rc site also. If you have the usb for your radio, picjoy converts it to serial port. then just run the picjoy checker to find the port its on. If you have done all of that, then in the FMS under controls select the bottom one I believe, if im wrong ill correct it, but then set the port to where picjoy checker said your radio was on. Then just calibrate and select the correct channels.
