Airspeed Sensor not calibrating
13.0rc1 airspeed calibration not possible · Issue #19772 · PX4/PX4-Autopilot · GitHub
Servo direction not working in stabilized mode
13.0xx testing. Hi Would be interested to hear how many fixed wing users do testing. I experience issues with rc1. (i.e airspeed, servo direction in stabilized mode if orientation of pixhawk is not default. Quite a big number of parameter do not get set to the default value even after a full parameter reset. I have not seen this from 1.11 to 1.12 ( I am testing on holybro 4 and 4 mini)
