I don't think the point was that a glider won't stall in a steep turn.
I think the point was that in some gliders with the CG far enough
forward and a small enough stabilizer, the stabilizer can not produce
enough down force when in high G turn to get the wing to the critical
angle of attack and thus stall. Limiting the stabilizer/elevator is a
well known trick to prevent (or least make it more difficult to stall)
stalls if power aircraft, both Ercoupe and Stinson used this trick.
Flying glider with an aft CG and/or large stabilizer will definently
stall in a steep turn. Other might be made to, but it are more
difficult to stall in a turn.

Don't agree to the idea that the glider won't stall in a steep turn.
First, the stalling speed at 60 degrees of bank is higer due to G forces,
and second, if you point your nose up (with left rudder in a right handed
turn, for example) the speed will drop and cause a stall, even a spin. This
could be very dangerous in a crowded thermal. You can also pull up your
nose, as when entering a thermal at hight speed and pull up, and then bank
hard to center the thermal. Nose up, speed drops, steep bank. Then stall,
maybe spin.
Stall is only a function of AoA, wich is in turn dependant of speed, wing
load and G-load (hope I don't miss anything). Nothing about bank angle
there, IMHO.

Good flights,
Jose M. Alvarez.

The danger here is that we are talking theory where
we may start to confuse pilots. It is harder to stall
with 60 degrees of bank. Gliders like the K13, by
design run out of elevator in straight and level flight.
They are difficult when flown with heavy pilots to
develop more than a mushing stall in sraight and level
flight.
