I just finished setting up a new drone with a Pixhawk4 mini and when programming the radio, I get error messages saying the Mission and RTL modes respectively are not available. There’s a good GPS lock and the radio is programmed correctly. There’s a local Mission plan uploaded to the FC, the flight controller just won’t switch to these modes. Is there a parameter anyone knows of that will affect this?
Problem solved. I re-mapped the transmitter switches in the calibration screen and all seems to work as it is designed to work.
