Scale time is a valid concept.. If you andI were scaled down to the same scale as our planes our hearts would beat faster, our whole bodies would 'run faster',our watches would also run faster. To us then the scale plane would now look like it was flying at normal full scale speed, even though to the rest of the 'big world' it would seem to be flying too fast for scale.
if you went further and scaled down our solar system the planets would spin faster and orbit the sun faster, days would be shorter... Time would indeed 'run faster'

Of course when we scale out models we dont scale ourselves or the rest of the world, which is why a true scale model appears to fly too fast to us 'big people'
