Your CG finder will only be accurate on finding the proper CG of a good flying model. In the example I posted on a gearless plane, it finds the CG. It is the center of mass, but it wont fly at that CG. So...lets say you build a plane, mount the gear and use the CG finder. If you havent gotten it set for a good test glide, the CG is a false one. Its not the flying CG. The CG on a good flying plane is actually the center of the mass + a bit forward weight to initiate the glide and prevent stalling.
Does that make more sense?

That's always been a problem for me when building planes. I usually
just took it 1/3 back from the leading edge of the wing and went from there.
Then swept back wings and this canard threw me off.
