Patrick,
As far as I am aware the Suisse use this description for all refitted/ and recoated PC-7's. I've seen it mentioned a couple of times the last year of so.
Ofcourse I could be completely wrong
Thanks for the information! So if I understand the article correct 18 have been upgraded so far, another ten will follow and the remaining 9 will be stored/sold/scrapped (1 is preserved and three have been w.o.)? Is it correct that all the upgraded ones have the new c/s? That would be an easy way to recognise them
