The larger rudder is because of the 17.5/18m tips on the LS6-c.

I've been looking at the LS-6 gliders lately and noticed that on the
LS-6C the rudder looks almost twice as big at the root chord than on
the LS-6A. Is this an optical illusion, or is it real?

I am guessing that since the later version of the LS-6 had tip
extensions, the rudder was resized to allow for that.


Yep. Correct, the LS-6C with 17+ meter wingtip extensions got i bigger
rudder to give it a bit more bite which is needed when that looong wing
starts to generate drag when starting the roll to turn.

Would love to hear from any LS-6 drivers of the "smaller" rudder
versions how the bird handles, especially regarding rudder inputs.

I have an LS-6b and the (smaller) rudder is more than enough on that
one. Feels like a sports car to fly, more than ample rudder authority.

Our club has an LS-6C which I've flown many times and it is very nice
also but doesn't quite have the same roll-rate as the LS-6b when flying
with the looong tips.

So, what about the LS-6C with short wing tips on ?! Well, when thinking
of it, I don't think I have ever flown that one with short tips :-). I
have to try next time I get an opportunity, just for the sake of
comparison.
