Not quite, these slats are air-loaded; i.e, there is no mechanical,

logic in the FCS, air data computer, or crew activation to extend the slats.
Part of the walk-around is to physically push the slats up and see that they
drop freely. I don't think there are any aircraft currently modeled that
have this sort of slat system, so the point may be mute.
The Helio Courier (which I'd love to see modeled some day) uses this same
leading edge slat arrangement. The slats are divided in half on each wing so
there are actually 4 independent pieces. These are aero-loaded and drop down
at different times depending on small differences in friction, and differences
in slip and air currents. It's a bit disconcerting if you aren't expecting it
though ... they bang down rather loudly when they go.
These same aircraft also have a small spoiler near the end of each wing that deploys in low speed
configurations to help maintain roll attitude. These things can do steep (controlled) 45 degree
banked "S" turns at 35kts. The spoiler is a small piece of metal that extends vertically
out of the wing ... their's no rotational or hinge aspect to it, yet it's tied to the
"wheel" or aileron control.
The Helio is really a nifty little airplane for what it's worth. Here's a
