adjust the CG or trim
I have a Fliton extra 330s freestyle and I can get it to balance a little nose heavy on a CG machine but I have to be right dead on the angle where the plane will balance or else the tail or nose will drop in a second. When I'm flying the plane and let go of the controls the plane will dive fast!, so should I trim this out or move my battery back and forget what the CG machine is telling me and adjust the CG to what the plane is telling me?. I'm balancing the plane with the fuel tank empty , plane upside down and the fuel tank is maybe 3-4 inches behind my saito.
Thanks
Greg
