I had the same problem with mine. The closest I got my CG was 5" from the leading edge. That was where I started & thats where I left it. I could not have asked for a better flying plane. The balance turned out so netural that when you cut the throttle the plane wouldnt drop nose or tail until it completly quit flying. Inverted flight is completly hands off, into the wind it would climb! I programed about 20% expo on low rate for the down elevator because you actually have to give it a little on landing if there is any breeze at all. If the darn thing wasnt so heavy I think it would be the greatest plane I ever owned.
