Out of the box the system appears to be using RC=CRSF_RAW in the /etc/modalai/voxl-px4.conf file. This results in 'px4-listener input_rc' returning all zeros for stick inputs, 16 channels, and rssi of 0, and rssi_dbm as 'nan'. QGroundControl shows the channel monitor, but the sliders do not respond to stick inputs.

When I change to RC=GHST 'px4-listener input_rc' shows the same as CRSF_RAW above, QGroundControl shows no channel-monitor section at all.
