End of story.

And that would be why? You'd be revoking a lot of CFIG tickets.

Along with emphasizing the importance of foot work, hopefully he's
talked about the dangers of over ruddering and stall/spin accidents
and talked about how different gliders handle and may or may not
really benefit from early rudder application. And hopefully he really
works on decreases focus on programatic things and transitions
students to developing a feel for flying these gliders.

I teach in a ASK21 and previously G103. Both exhibit adverse yaw very
clearly.
The only way to "coordinate" the turn in one of these is to begin with a
touch of rudder, a tenth of a second before the aileron. Well, actually not
quantitated but just to illustrate the idea. The nose must begin to turn
(let's say) left as the left aileron is applied. If the student is a bit
late on the rudder, the turn will just look and feel a bit "sloppy".

So, I say "just start the rudder first, then bring in the aileron, to make
the nose move in proportion to the stick." This will keep the string
centered. Most students are late on the rudder, so this gets them "caught
up".

This is not necessary on our club single place gliders, but by then, the
students know how to coordinate a turn by how it looks and feels.
