Hi Raz,
you see on the control surfaces what auto trim did, slight deflections. You can always dial it back to zero, or so the control surfaces are flush with the wing/rudder profiles, no problem.
Some even take off with auto trim enabled (at least some who hand-launch their models have reported that).
I always only used it in a stable flight attitude, though.
Kind regards
Eddi
