A VERY effective demonstration of this can be done in a P51. You start
from slow flight with the prop all the way up and slowly begin
increasing angle of attack and feeding in more MP as needed to hold
altitude. Sort of like any entry into a slow flight back side scenario.
As you do this you will need more and more right aileron. You will reach
a point where aileron can't hold it any longer and the airplane will
torque roll on you.
It's a VERY effective technique for demonstrating how NOT to get in high
angle of attack/slow airspeed/high power situations :-))

I understand the reasoning/description here, but how/why do model
planes do it so well?

It's in the ability of the ailerons to handle roll inertia. The
propeller on a Mustang for example is a Hamilton Standard 24D50. It's 11
feet 2 inches in diameter and weighs more than a Mother- In- Law! That
monster can create more left turning tendencies than NASCAR. In the
described scenario above, it's simply a battle between the prop and the
ailerons. The prop wins in this case.
