Helipix and Sav, the pic of Gazelle F-ZWRK/04 reminds me that I flew the aircraft several times in early 1971 as the AAEE project pilot.In May we were doing Stability Augmentation system (SAS) handling and `runaways `; later in the month myself and Cne.Castres(my CEV counterpart) did high altitude tests to 20000 ft. We then flew it from Marignane to Bretigny the following day.
With regard to the `Roo` on the fin,it may be that it was put on by an Australian TP that was at AAEE,but I do not recall that the aircraft was ever in the UK,but he may have flown it in France.
