...Can I move the wing an inch back of the fuselage to get proper CG? Any recommend....
I’m not super familiar with the Legacy so take my comments with a grain of salt.
Yes, you can adjust the wing location to achieve a proper CG.
Another alternative, cut the nose off and make it longer. Sometimes I will add 2-3 inches to the nose of a plane. Extend the power pod outwards until you get the plane to balance. This will give you a good idea how much to extend the nose. I cut the nose off and glue in my extension, then glue the original nose back on to my extension.
I recommend you use less glue on your next build. My goal is to use only 1 stick of glue for a plane. Hot glue is heavy, a little is all that you need.
