I seem to remember the military teaching for an engine failure IMC in a Gazelle was to :
Enter auto ( 35 kIAS constant attitude profile to minimize ground speed )
turn into last known wind.
enter standard 60 kIAS on cloud break when you gain visual references.
carry out normal engine off landing
OR
If no cloud break or in FOG maintain 35 KIAS until 35' AGL ( rad alt )
Initiate constant attitude engine off recovery ( No flare )
