What ,in your opinion, are the 'significant issues' with the Astar? I would not venture an opinion about a 407 if I have no time in it and I see you do not have time in an Astar.
If you are going purely by folklore, then I can say that an Astar with Arriel engines has a sterling record as far as engine failures go.To me, the Astar is a superior machine in every way.But then I am biased towards European and Sikorsky products and underwhelmed with the current line up Bell has to offer. But I will not make that a blanket judgement until I fly the 407/212/412/205/206.
