I guess it depends on the make and model. In Recurrent Training at PHI when I was there, they taught a technique in which the *first* response to the engine-out was to come back on the cyclic. In an auto-entry from cruise airspeed in a 206, if you merely lower the lever without coming back on the cyclic the helicopter will immediately enter a descent. And if you're only at 500 feet to begin with, you've really screwed yourself if you subsequently have to turn into the wind. There's a lot of energy available as you decelerate from 120 mph to 60. Might as well not waste it.
