Have a play around with atc_input_tc (previously known as rc_feel). Bump it up to reduce the responsiveness of the craft, but don’t go too high otherwise you risk losing control. Keep it around 0.3 or below if you can
Agreed: ATC_INPUT_TC to 0.2 or 0.22 is typical as a starting point. In MissionPlanner channel 6 tuning it’s shown as RC Feel - set the range to 0.15 to 0.30
