www.videosouth.com it is titled 'the robinson R22.'
I have no pecuniary interest in the outfit. you will find the vis is excellent.
The aurals are also 'very' interesting, like -'its got 180 horsepower!!'

Yes there was a major problem with the original blades;
-1's- low inertia and a quality control prob which snuffed out a swedish guy that trained with me at Air-Log;
-2's had better inertia- well they did to any of us that had flown -1's where it was reef at the bottom and whoosh became whhhhoooooshhh in a about three revs. -2's also had a creeping corrosion prob interrelated with a structure prob but really most of the failures they had would not have happened if the players had stuck to the rules;
-3's never hit the stands;
-4's that we now have are showing a debonding at the outboard end of the doubler. as per imabell's original post
so far our info is that there are 4 in OZ, 2 in US (one from canada) and a suggestion of 2 from NZ. serial #s as far as we know in the 1000 to 1100 and age from 330 to 780hrs and yes, it may end up costing several arms and legs.
