Changing size of model with animation

How do I go about changing the size of a model which has animation from a script?

Within the gui I am able to do this using the inspector of the original model and changing the “Scale Factor”.

If you use an animation that has been procreated in a modelling program you can’t actually change the scale without having to redo the animation (or atleast mess around with the animation data inside a modelling tool), since the positional, rotational and scale data are saved within the animation clip.
