Actually, "stomps them all" is probably a bit rhetorical.

I've got a couple of the sim models flying just like my real models. After having tuned my real ones better. And now I'd say the sim is very good at simulating whereas before my fixing my models to fly better, I thought the sim wasn't very good.

Now I'd say it's good. As for stomping them all..... I ain't got them all to know.
