ArduPilot to the latest release V4.3.1 --> V4.6.3
RX switch from FrSky R9 to ELRS. Elimnate the outdated/unsupported protocol and module. Looking at dual band Xross Gemini options. (915M/2.4G). Probably go with the XR4. I picked up a RadioMaster Nomad module to play with the latest/greatest ELRS options.
