RE: CG Ultimate 10 300 CG
Twistr, I have the kit not the ARF but the plane is the same I think. I balance mine inverted using the bottem wing. (which is on top since the plane is inverted) I have it at 3-1/8" best I can tell. I am having to use my finges since the CG machine won't work on this plane. It will knife edge loop/flat spin/Lomcevac, you name it. Come to Elk City for our fly in on Sept 17th and I'll let you fly it.
