I forgot to mention that this plane is a ARF. I have used all hardware that was included. I have three standard Futaba s3004 servos in the fuselage. There aren't any modifications, just a bone stock arf. The only thing that I could think of that would make this plane nose heavy is the 46ax. I checked the O.S. website and the 46LA weighs 9.6oz compare that to the 46ax which weighs 17.2oz.
