I find it hard to believe that two ATPL "senior" instructors with 30000 hrs between them have got that far down their careers without noticing that swinging a prop on this type of aircraft is quite normal and does not warrant shaking of heads in disbelief.
It begs the question, what exactly do they think of the general competency of pilots who are not known to be quite so God like as they obviously are?
If I were the Stampe pilot and read this thread I think words would be exchanged.
