There is a skill set that a pilot must learn if he is to be able to
check himself out in a new aircraft.

What is this skill set? I'm not aware of anything specific along these
lines from the instructor/instruction manuals I've read. Generally, once
I'd trained a pilot to fly in a Blanik, he had most of the skills needed
to fly one of the usual single seaters.

Think for a moment. If you're checking yourself out in a glider,
you're going to do some stalls in it, right? And they're going to be
true approach-to-landing stalls - starting with a stabilized descent
at pattern speed, with a speed reduction to mimic the flare. Gives
you plenty of time to feel what the glider is going to do.

Suppose we didn't teach stalls that way. Suppose we taught them as a
performance maneuver, where the goal was to get the nose high, get a
clean break, and minimize altitude loss at recovery. Would the
student still be prepared to figure out the landing characteristics of
the plane?

Apparently, I'm still missing the point: why is a 1-26 or ka-8 far
better for soaring flight?

Because it doesn't handle like a truck. Because it's relatively
(compared to an L-23) easy to reg and derig. Because it's a single
seater, which makes it easier for the student to cut the apron strings
and for the club to let him go, whereas the two-seater is needed to
train more presolo students.
