If that Battery position is where you are comfortable, and yet the trim is all the way back, the only way is to do mechanical adjustment. As the Hughes linkage is not screw type, you have to remove the servo horn on the elevator servo and shift 1 notch to make up the trim back to neutral position. May be off alittle centre but it can help tremendously. Try it
