Hi Madman, How did Robinson resolve the problem with your 2nd set of blades? Did they cover 100% of the cost of the first set of blades? (freight, brokerage, install, balancing, etc) Doesn't really matter if they sent you a faulty 2nd set! How much did you have to "arm wrestle" with them to get any action? I have the exact same problem with a set of blade I just installed with now only 50 hours. I wonder how many more R44's have the same problem?? I would post a picture or 2 of my blades but I can't attach a URL until I have 10 posts on the forum.
