For all types with engines under the wing (on airbus there may be auto trim), the take off calculated STAB TRIM is only valid for all engines operating.In the case Centaurus is discussing, engine out while still on the ground, I teach the following.

Apply enough rudder to keep on centerline, and plant your heel on the floor, so it doesnt move.
At Vr rotate slightly slower than for normal take off to the target pitch attitude (10-12?)
Apply 2 units of NOSE UP STAB TRIM.
Then apply rudder trim to unload the pedal pressure.Now there is very little control force needed to fly the machine.

It is worth noting that the requirement to apply a CORRECTION ie 1-2 more units of nose up trim than the uncorrected loadsheet figure which is typically produced based upon full thrust, when using a large thrust derate is often hidden in the weight and balance manual somewhere, but it makes sense doesnt it?
