I was always told that rotational weight is equal to 4 times the actual weight---- that means that for every pound the effective weight that the engine is trying to overcome would be 4 pounds--- now this may depend on how great the diameter of the object is--- in other words if you have an item that is 2 inches in diameter the rotational weight difference will not be as significant as say an item that is 12 inches in diameter where it should be greater--FED 387
