Blanik L13 VS ASK13 handling and aerodynamics ?

http://en.wikipedia.org/wiki/LET_L-13_Blan%C3%ADk

"These are in effect typical of wood-and-fabric primary trainers such
as the ASK 13, which the Blaník resembles in handling, though not in
materials, construction and aerodynamics.

For this reason, pilots trained in the Blaník require differences
training in a modern two-seater before transitioning to high
performance plastic single seaters."



Greetings,

I am wondering what the differences they refer to in this article
are...

Would anyone be kind enough to take me through a comparisson of the
Blanik L13 vs the ASK 13 and later on the fiber glass gliders'
handling. I am surprised by this statement that tends to say the ASK13
would be closer to fiber glass gliders in terms of handling and
aerodynamics... so the Blanik L13 would be different, away from the
crowd.

My own personal understanding would tend to say that the L13 and ASK13
are closer with each others in terms of handlings. And the modern
fiber glass machines would be a lot different.
So what's the L13 difference? Sharper when stalling or entering spins?
What's that point about the laminar wings? Don't modern gliders have
kind of laminar profiles too?

Look forward to reading you guys...

Many thanks,

Lovely Sunday,

Matt
