Since I updated to 3.3.0 I see there is a new param named ‘RC_TRIM_AT_START’.

Can anyone explain what effect it has beyond what is currently in the wiki as it’s not exactly clear…

Automatically set roll/pitch trim from Tx at ground start. This makes the assumption that the RC transmitter has not been altered since trims were last captured.’

The ‘default’ for this is ‘enabled’.
