I flew with UWAS in the seventies and in HongKong in the eighties. The same basic aircraft but different performance due to temperature, humidity, etc.
The annual airtests never came up to the book figures but a superb aircraft
for training. We replaced them with Slingsby Fireflies which were not as rugged but nicer looking.
At UWAS I remember my student putting 6 G's on the meter during a PFL and my boss (Adam Wise) giving me a quick reprimand so that he could tell the AOC that the matter had been dealt with on the squadron. Never heard anymore about it!
