Man do these blades work a lot better the the old black platic ones that come with it. I never did like the looks of them but it was a good deal when I bought the whole setup. Now I would like to have a bigger generator on there. The tower is Rohn 25g @ 60 feet. I winch it up with a hinged base. I wanted to end up with 70 feet but 60 was scarry enough. 50 feet seemed ok and I might go back to that when I get the trees cut down.
