I've been building for many years and in my experience the CG is usually between 25-30% back from the leading edge. In this model, it is telling me the CG should be about 42%. It seems to me this is to far back. Has anyone flown the Nitro Planes Cessna 310 (88.6 wing span)? And if so did you have the CG where they said or did you modify it? I would hate to fly with the wrong balance and loose the plane right away!! Thanks for any help!
