Does the specified C G change with heavier motor/batteries ?
Let's say a plane comes with the C G specified for a certain location, say, 2 inches from leading edge of the wing.
If I install a heavier motor and esc, I don't balance in a different spot, do I ? Don't we move the flight pack or something else to maintain balance in the factory location ?

Depends on the design and the amount of extra weight. For a standard clark y type airfoil and a flat plate stab + 20 % in weight or so, you're probably OK. For an undercambered wing with a lifting stab- move the c.g. forward as weight increases. It's often not a bad idea to sneak the c.g. forward a bit for first flights-and set a little extra up in the trims. Nose heavy airplanes get retrimmed, tail heavy airplanes get rekitted.
