Thanks for that, but I finally recalled the one I was thinking of: the
"RealAir 172SP". It can do slips and spins, and felt pretty realistic
compared to the stock one.

Rob Young and his team at Realair have done some wonderful work with slip
realism in MSFS.
It took some fancy programming too from what I understand.
Using pedals, the sim pilot is afforded a much closer accuracy factor toward
the aerodynamics involved in an actual slip, but there are aspects of the
equation that are extremely difficult to program into a simulation. For
example, the rate of sink due to drag in a slip will vary a great deal from
airplane to airplane at various angles of attack and amounts of applied
opposite rudder to negate the turn. Its a VERY complicated formula.
Mild slips have been possible using the default aircraft in the sim using
rudder pedals but the tendency to turn into the low wing has always been
there and becomes prevalent if the low wing is banked past a very low angle
of bank. In other words, using defaults, the bank angle overcomes the
adverse rudder required to create the slip by negating the offset lift
vector.
Realair, with some absolutely magnificent programming, managed to improve
the aerodynamics required for slips in their add on aircraft. I can attest
to the fact that their Spitfire for one, handles in a slip in the sim
exactly like its real counterpart, as does the 260. I haven't tested the
172, but I'm willing to bet the house its as accurate as the others.

The other thing to remember is that the cross controlled condition in a
forward slip is a perfect setup for entry into an inverted spin or an
outside snap roll, which can be particularly impressive on short final in a
Cherokee.

Okay, just out of curiosity, what do I have to do to enter the
inverted spin or snap roll?

And what is a snap roll, anyway?

That's why I said "by default is configured" instead of "you have no
choice."

I've read it has something to do with its inability to calculate the
lift, or perhaps just the default aircraft don't handle it. However,
I believe some third party aircraft explicity address the slip issue.
What's that C172 realistic addon? Drat. I've forgotten, but it's a
far better 172 than the stock one.

From the descriptions I've read here and elsewhere, it seems to slip
as a real aircraft would, even with default aircraft.

Lately I've been just flying the plane, rather than practicing precise
movements in accordance with regulations, and it seems rather easy to
control. Eventually I'll have to get some rudder pedals, maybe, as
controlling the rudder by twisting the throttle requires a lot of
practice, and I don't know of any real-world aircraft that works this
way. Trying to maintain a coordinated turn is a challenge.

That's a major reason why simmers who don't own rudder pedals get
little of the realism that the sim can sometimes offer.

I was thinking that it would be a major reason why some people might
not get the realism they want in maneuvers; it's not that the sim
can't do it, it's just that the default configuration locks the rudder
to the ailerons.

You might want to do it in an emergency descent situation when you find
yourself very near an airfield and are too high to make a normal
approach and you've to suddenly lose a lot of altitude.

Hmm ... looks like a pretty comprehensive explanation.
