The first thing that interested me was the position of the second AH which was on the co-pilot's side
Centaurus, like me, has a concern with stupid instrument panel layouts. While not arguing against the contention that inexperience and lack of training don't fit well with increasing aircraft sophistication and speed, the inside additional difficulties due to panel layout is a very real problem.
Historically, there have been more than a few fatalities where inappropriate pilot controls/switching has been implicated in the causation.
From a design point of view, the underlying requirement is that panel stuff is supposed to be assessed for acceptability by appropriate FT folk. For whatever reason, in Australia, that has never been a driving consideration in the airworthiness field.
As an aside, I well remember (from very long ago) an endorsement on a single seater done in a hurry on the Friday so I could do the glider towing on the weeked to help out the gliding club. The endorsement was done in weather which might not have been considered ideal ... but that's another story. The point of this yarn is that the ASI was stuck up on the top of the instrument coaming (go figure ?) and, due to the low weight and relatively big motor, on the first takeoff the bird went like SOAS and I found myself about three circuits behind the aircraft. By the time it was well off the ground, I eventually found the ASI, which helped out just a little bit. By the time I had ripped around a (fairly) low circuit, all was well and a little bit more saw me happy with the aircraft. I can't recall whether, subsequently, I ever got around to having a look at the bird's stall characteristics but, that again, is another story for another day.
There be dragons out there for the unwary. I thought an observation the other day from a colleague, in regard to some of our newchum theory students was very pertinent -"Wisdom and hindsight are two sides of the same coin, they (as in the students) have yet to discover their piggy bank is empty".
