You are correct in that the cg does move when the attitude of the a/c is nose high or nose low. The c/g does NOT remain constant regardless of attitude.
When a Full size A/C is having the weight and balance done to determine the cg ,the a/c has to be in the flying position as it would be when trimmed and flying straight and level. [this is in the manufactures spec]
If you change that positon then the c/g also changes. This is what you are seeing on your machine. Beleive what it says and balance your plane with that ..I have one and it is very accurate in determining the c/g ... cheers.
Very WRONG. The CG is a fixed point regardless of the position of the model. The only way to move it is to redistribute the mass withing the model (including structure) or adding additional mass somewhere within or on the model.
