Light helis are banded together so if you fly 206 , AS350,enstrom480 and say gazelle then you only have to do one checkride to cover you for all types that you have on your licence , so long as you are current (2hrs) on them . This is a great saving but make sure the examiner/instructor marks it in your licence that this is a group renewal and not just the type you did ride in . I think Robbos are different and are in a class of their own !!!
