I have a Sig Something Extra I bought from a club mate last year. He sold it to me with an OS 52 FS and a MA 10x7 prop. I really enjoy this plane. I can do most basic aerobatics with it, and it lands like a dream. But, I can't quite hover it, and knife edges don't last. I'm considering putting on an 11x6 prop and maybe moving the CG back (although I think I like it where it is). I don't have the manual for the SE or the OS 52. What say you?

Thanks for any help?
