That there is good stuff  

 baby sitter.  Very useful, and pretty much does not negatively impact flying skills unless you use it from pickup to set down - aka beeping to a hover and acceleration to beeping down to the surface.  

If you do the latter on a floater (aka offshore barge) make sure you disconnect the whole AFCS or the rotor disc will respond to the movements of the structure ur on, oh, and make sure you don't do the beeping down thing.

Now wasn't that a nice response.  Somewhat factual.
