Hi,

Have you notice that this plane, after landing, decrease speed really fast only with reverse?? Is that the way it should be? At least in other planes, like defaults one, it takes a lot longer to redude speed.

Yes, I noticed it stops really fast.
I don't know how realistic it is, but bear in mind that the real 727 was conceived for small airports, without 5000+ ft runways and the lot.

That's the reason it has nose wheel braking (very rare on airliners, and even aircraft in general) and built-in air stairs...
