I cant speak for Eurocopter, but after talking to sources I have been advised that there is no "Instructors Course" per se. Only an initial check out geared for one who is an Instructor.
As to the fenestron I have been told the only subtle difference is that fixed pedal operations call for Autorotation verus what some are used to during emergency procedures.
Im sure someone will work me over on that, but its pretty close to being from the horses mouth.
