Radar,
Here are some pix of my plane built. The engine, mount, muffler, and battery weigh 4lbs 4 oz. The standoffs may weigh another 3-4 oz. The total weight of the plane is 16lbs 8 oz dry. The CG is at the very back of the range 5" from leading edge. It requires absoluley no down elevator when inverted and raises the nose slightly as it slows to land. I am going to try and move the reciever battery forwar some to move the CG forward about a 1/4". I dont see how your plane can be so nose heavy. My rudder servo is way forward. If yours is in the tail your CG should be close.
