First flight with my fixed wing. FBWA works ok, just need the normal tuning.
Automatic modes as LOITER and RTL don’t work. Airplane pitches up, lose speed, accelerates, stalls…a mess.
Compas calibration done and repeated.
It is my first time with this issue and i do not know where to look in the logs (attached)
Cube Orange
2 GPS (1 CAN and 1 serial)
2 Arspd sensors (1 CAN and 1 serial)
3 Compasses (1 internal and 2 from GPS)

Did you checked if all rudder work in the correct direction if you switch to automode?
Using automodes on the first as I understood untuned flight will be not the best idea.
Which method you follwed?
Ok, it is not fine tuned yet, but it flyes without problem in FBWA. That is why i switched to auto.
I usually do this so later in the log i have everything i need to fine tune more parameters like ptch_trim_deg, TECS parameters, auto_tkoff…and all of that stuff!
From what i see from logs, as soon i switch to auto modes, the autopilot immediately asks for 20 degrees of pitch. This is my pitch up limit.
This happens even if we are flying at the correct altitude (like in loiter)
Minimum pitch has a positive value! This means autopilot wants to descend, but actually climbs. This also explains why it cut throttle while climbing (it wants to descend)
