On the ground the ailerons tend to flop around whereever you turn them.
They also flop in the wind a lot (which is why you tie them down). Once
you start rolling and air goes over them they (in modern, non-aerobatic
planes) tend to return to center, like a car's wheel.

And does this happen before you actually have enough control authority
to use the ailerons, or roughly at the same time that you have that
authority? I'm wondering if the airspeed sufficient to "neutralize"
the surfaces is lower than the airspeed necessary to make them useful
for controlling the aircraft.

BTW: On high performance planes moving the rudders also moves the
ailerons because they are interconnected to create smoother turns.
Slipping requires working against the springs and requires a little bit
more strength than on a C-172.

FWIW, I successfully slipped the Baron yesterday, I think. Being at
about 6500 feet for a runway only a mile or so away at 30 feet, I was
able to lose thousands of feet fairly quickly by slipping. The
aircraft in the sim seemed to behave just as I've heard it described
for slips in real life.
