I have this RC model and almost finished building it. I am confused on the CG for this plane. The manual that came with it is on a CD and shows an Extra 330 at times in the photos when they reference some thing. The manual shows the CG at 130mm but in a discussion of the plane on Hobby Kings web side a person says he contacted the manufacture and the CG should be 163.5mm. I am good at 163.5mm but tail heavy at 130mm. Has anyone flown this plane? If so what should the correct CG be?
