I have a MC-26/GR16 config that I want to connect to a APM2.6 installed on a Quad drone. I just received it second hand. Pervious owner used Turnigy 9X with a ImmersionRC ezUHF module. Trying to install the GR16. Using the Mission Planner wizard all goes well until I get to the radio set up where it does not get any connection with the radio. I have initialised the Sum0 and connection with the RX.
Any idea what it could be I have not done…
Having a FrSky Horus X12S w/X6S as backup…
