Its one of the first things you bang into new FO's is trimming her properly. And for me its Elevator rudder then roll as well.

You have to watch though going for preflight settings same as cruise settings.

Some aircraft which are right at the edge of the envelope pre load for a engine failure of the critical engine. If you trim for the cruise you will come a cropper or the whole V1 cut will require considerable more work and leg forces.

On my type you have several trimming settings, every flight phase requires it to be changed and every aircraft is different. It also depends if you fly them on matched EGT's or matched torques or the really bizarre one matched levers.

But the setup for departure according to the book is the rudder slightly favouring a failure of the critical engine (half a unit), neutral roll and green band for the elevator. And for the other flavour of this type with smaller engines its everything neutral and green band for the elevator.
