Yet to Fly at Ardmore?

Back in February I did a post on the various types of BK 117 helicopter, see:  http://nzcivair.blogspot.co.nz/2015/02/ardmore-23-2-2015-bk-117-helicopters.html

Now when I was at Ardmore last week, I spied yet another type of BK 117, as revealed above.  It has a much larger undercarriage than the standard BK 117.

However I suggest you click to enlarge the photo and note the signwriting.  What a spiffing idea!
