I'm still in a bit of a quandry as to how to learn to make coordinated
turns
in a PC simulator that does not include a motion platform.

I've turned on the visual alignment indicator that MSFS provides, which is
a
red "V" that sits squarely ahead in the visual field, effectively bolted
to
the airframe. I've been trying to turn such that this V always moves
along
the horizon at a constant speed for a given bank angle. Logically, a
specific
bank angle in a coordinated turn will always produce a heading change at
the
same speed. If the speed at which the horizon is moving varies, the turn
is
not coordinated.

Also, it seems that in a coordinated, level turn, this V should stay at
the
same distance above the horizon throughout the turn.

As I roll into a turn, the speed of movement of the V along the horizon
should
increase in precise relationship to the bank angle. The opposite should
occur
as I roll out of the turn, with the speed along the horizon slowing as I
return to level flight.

Any problems with this? The only remaining problem is to figure out _how_
fast the V should be moving for a given bank angle. Maybe that can come
with
practice.

Does this help?
For a given bank angle ( theta) the time taken for the heading to change 360
degrees in a coordinated turn will be given by

t = 2 Pi v / g tan( theta)

t = time in secs
Pi = 3.14159
g =gravitational accleration 9.8 m/s2
v = speed ( m/s)
