Paul, I waited three months for Anthony to send me new bolts and then I ordered them from aircraft spruce. when I put it all together I came up with 2 ** negitive pitch with no way to fix it. I bought an Skywheels hub bar from helicopter Ed and mounted the blades. My original hub bar is scrap. I told Anthony about a month ago about my problem, still waiting for his response. I wish now I would have put all this on the forum before any body else got ripped off. I wish you luck, may be he will fix it for you.
