Ventus 2cx brake

Several reasons:

(1) No spoilers (like the HP-18 or my whale mentioned above)
(2) Some people hate messing with spoilers to prevent rope
overrun at hookup, because of operational considerations
or because...
(3) Many gliders pull down flaps with spoiler activation, so
if you pull spoilers back to use brakes now you need to
push flaps back up (take-off and landing)

I think that's why many gliders have both...
Why it never works ? A long rant plus discussion above...

Which gliders add flaps when spoilers are activated?

IIRC, LS, DG, Lange...

Ventus A/B and many Glasflügel ships.

Those are just brand names, eh? The LS-8 and the DG-400 don't add flaps!

I believe the Nimbus 4 adds flaps with spoiler acutuation.

My LS6-b does.

DuoDiscus x and later have interlinked airbrake and landing flap.

I should have been a bit more precise.
Some readers are not confused by models that have no flaps, but... ;-)
The issue is when the SPOILER CONTROL moves the FLAP CONTROL.

There's no problem with putting the wheel-brake on the spoiler
with ships like the Ventus A/B, as the inboard flaps are pushed
down by the trailing-edge spoilers with-out moving the flap
control. If you select negative flaps for take-off or landing,
then pull full spoiler, the flap CONTROL is unaffected and
the outer control surfaces remain reflexed up as you
pull the spoiler handle.

The SPOILER CONTROL moves the FLAP CONTROL back
in many FLAPPED gliders, for example recent FLAPPED
gliders from LS, Lange, and I believe DG. This creates
a bit of an operational issue with wheel-brake on spoilers
only.

In Antares, it is not necessary to use negative flap for
powered takeoff or for landing roll-out as roll control
is extremely good at low speeds (and in general). It
does create a nuisance if you want to use negative
flap for aerotow takeoff, only necessary with a wing-
runner. For Antares my preference is no wing runner
even for aerotow, which may seem odd but works
extremely well. Even with full, water, its no problem.

Hope that's a bit more clear !
