Help with CG math

Hey guys,

This is more of a mental exercise, but it could save me alot of tinkering in the garage. I have a 5 pound plane that I want to move the CG back. I can move one component that will reduce the moment on the nose by 6 in/oz. another will remove 13.3 in/oz. The question is knowing these moments can I calculate how far each will move the CG rearward?

Thanks for your help,

Chris

RE: Help with CG math

Found it:

CG shift = (weight of object moved) * (distance moved) / (total weight)
