Hi All

not sure why but every time I switch from Auto to RTL the plane pitch down almost crushing before starting to climb to ALT_HOLD_RTL.

see attached picture, and log is at:

Please help debug.

your elevator _TRIM setting does not match your TX config, airspeed is far from correct, , none of those causes it, but you need to check everything as even such basic things are poorly set up.

can you be more specific? what do you see the is poorly setup?

-elevator trim (RC2_TRIM) is not what you radio does.

-airspeed is wrong, seems to be much higher than GS regardless of direction you fly in.  , correct or learn ARSPD_RATIO
