Krayzc, I first had it at 4.5" as others recommended which is kind of middle of MFR recommended. Almost full down for level flight inverted. If the plane is trimmed right and the CG is at optimum, it should be hands off inverted. I moved it back to about 5.25" and it is much better. Battery is now by the wing tube so I'll have to build something to attach it to, futher back. Don't want to add any weight, even a little to the tail. I also have to rebuild my stab cause it broke off after a violent knife-edge spin. Probably get some more weight there. Flying wires are a good idea.
