my su weights 25#, the cg is 1.5" behind the center of the wing tube. it is very stable all the time. i have no added weight. zdz 80, what a fun airplane. i have 65 flights on it. karl

Good to here that the plane can be flown that far back of the tube. I am going to remove 3 oz's at a time. My hope is that i can remove most of the weight from the nose.
