this is the first replied that I have written in the rcuniverse but here it goes I have successfully converted and flew a northstar with elevens. I started out by thinking that it might save some weight in the airplane but by the time that you are done it weighs more and that is because you have to add more nose weight than you start with because the tail turns out to be a lifting surface there are other mods that are a lot better for the northstar mine is setup so I could fly it either way with a little work and CG change but at this point I think I will stick wit the the tail on the plane
