GP Matt Chapman Eagle 580 CG issues

Hey guys I need some help. I am a GP Matt Chapman Eagle 580 .46 ARF. I am trying to balance the model and I am needing aout 14 ounces in the nose of this airplane to get it to balance out at the 3.75 inchs aft of the root of the wing. I was hoping that someone else has built one of these airplanes and could give me some advice. I called GP to get some help from them and they where not any help. The gentleman seemed to hardly know anything about building aircraft. Thanks

one more thing. I am wondering if everyone has put the balance point out at the end of the wing or at the root of the wing by the fuselage.

Mine balanced right on the money, upside down. I am running a .61 with a pitts muffler and my 5 cell battery is attached to the bottom of the fuel tank. I have specktrum servos all around, and the rudder servo is mounted in the tail.
