Holybro 6c mini and telemetry

I just bought a new 6c mini FC for my favorite drone. I’ve installed Arducopter firmware but can’t seem to get the telemetry radios or OSD to link up. It’s just a configuration problem but I don’t know the correct configuration or find documentation on setting up the new flight controller telemetry in Mission Planner. These boards seem to be optimized for PX4 but I prefer Arducopter for the Antenna Tracker capability. Any help would be greatly appreciated.
