Just an update. After much trial and error (and a few choice cuss words) I think I finally have this sucker fixed up. Just got a very decent hover in our living room just now.

Mr. Skinner (barak1001) really knows his stuff, and got me on the right track. Now just gotta replace my flybar, and grab myself another inner shaft and im back in the air =)

Thanks again, couldn't have got it going without your help!
