I have a slightly different perspective having done some work with PZL Swidnik in the past.
Technically, the W-3 is a pretty good helicopter. No one seems to know why it was never sold outside of some in Poland, a few in India(?) and two in Germany.
Did anyone hear about the W-3 being chained to the ground at the Berlin airshow in 1999 because the factory refused to pay money owed to a German? Not likely.
Anyone know the cost to overhaul a W-3 at it's ridiculously low overhaul time?
I asked perhaps the most senior man in Swidnik why someone should buy a W-3 and his response was 'because it's cheap' - had no idea of how to sell, or what great features his helicopter had. He's still there, from what I understand.
Engineering was pretty good, management much the other way.
There was a good reason why Sikorsky didn't buy the Swidnik factory and bought another Polish factory.
Sadly, the very good design and construction folks at the factory are suffering because of management.
