As an ex-Lossie GR4 guy, I popped on to the station's website to see if there was any sort of announcement about it, to see if I could catch some flying at the right times.
The "latest news" was the Lossie raft race in August 2016, and absolutely no mention of this anywhere.
Twitter to the rescue; lots of comments about it being that last flight of XV(R), but again not a lot of details.
