Default Flaps/No flaps...practical difference??

For simple long pleasure flights in the western US or for the rare flights in the Alps would I notice any real PRACTICAL difference between a Discus 2c and other flapped 18m ships? I have NO interest in competition. Thanks

One consideration is what to do when a tow is too slow and not getting faster, particularly when full of water.
Pull in an extra notch of flaps, or...

You'll have something to do with your left hand.

Well, on that pleasure flight, as he blows by you at 100 knots. When are we not in competition? And, the pilot has the same wingspan to do it...

Now, if you get a Libelle, you can out thermal them all!

Landing flaps in Schleicher ships give you a nice steep approach and aileron control once on the ground.

Negative flap helps with aileron control in the initial ground run on aerotow.

But each available flap setting gives you another opportunity to get it wrong.

Exceeding maximum speed for a given flap setting can make bad things happen. Pay attention to the white triangles on the airspeed.

What George and JS said and in addition, landing speed and the angle of attack needed to lift off at high wing loadings.

I transitioned from a flapped ship to an LS8-18. No regrets.
Unless you are flat out racing, the simplicity and predictability of a modern unflapped ship are wonderful to me. Only if going nose to nose at over 100 knots does this ship give anything up to a flapped ship.

OK, Victor,

After all the top posts here, what is going to be your pleasure, Flap, or no flap?

The only glider I refuse to get into; A 2-33! I think Schweizer hated instructors. That is why the back of one is built to fit a pretzel...

Looking like “no flap” for sure. Lots of great responses. Appreciate them all. Words like “simple”, “predictable “ and “sweet handling” are what I hoped to hear.
