Jerry L, mine balanced at 5 3/4 with no lead added. I was happy with this setup. In time I will probably move the Rx battery back and try it at 6 - 6 1/4. Plane was so stable at 5 3/4 I am sure the extra 1/4 - 1/2 will fly just fine. Snaps were crisp both entering and exiting and it does nice slow inverted flat spins at that cg. Am not sure how it will 3d yet. I am still not an accomplished torque roller. cbk
