If they make something that's defective and has been proven to be defective they should replace it. For me that goes for cars, helicopters, boats whatever. The blade issue has been an ongoing problem, I can remember as a private owner having to fork out for -4 blades for my R22 when they had problems with -2's. I think Robinson's attitude is very poor here. I might be shot down in flames here but I seem to recall lycoming issuing new crankshafts for certain serial numbers in the R44 series and from my recollection they paid for them and the labour costs.. I also know that a number of owners had additional charges because when they " opened up the engine" other unrelated problems were found but the point being is that lycoming took responsibility. If I've got this wrong my apologies but I think I'm correct. People who fly the Robinson product are some of its greatest ambassadors and defend it continually on here and other places from the slagging off it gets.. Such a shame that Robinson don't embrace this loyalty with great support. Poor poor poor Mr Robinson.
