Spot on. Re parachutes; not only picked, but also packed. Good riggers can
alter the way the parachute material is placed in the pack to make you more
comfortable.

Ditto to what Bruce said :
Absolute performance the "a" Schempp is a bit better - IF you fit comfortably.
Here in Uvalde Lisa Trotter [who is small] fit fine but cannot reach things
in cockpit - you need to be small but with long arms!
Talked to a Ventus 2bx owner last night who got the 2x version because it is
a longer cockpit [I presume like 2c] and he is 6'6".
It comes down to the designer, Klaus Holighaus made the "a" to fit himself
and the "b" to fit everyone.
Gerhard Waibel's cockpits fit the more "rotund", as do Grob.
LS are in between. Having spent 5 days trying different cusions etc to get
comfortable all I can say is comfort counts, parachutes need to be picked with
the glider in mind as well.

Tim,
Delta one goes better than any B I came across. ;-)
Mart,
Depends who you ask. The Discus A has 80mm more wingspan than a Discus B -
yes both are 15m wingspan, but the A fuselage has 80mm less width. Plus I think
that the bottom fairing between the wing lower surface and the fuse is more
aerodynamic - but I was an A owner of course. B owners reckon that the B fuse
was more aero despite its girth. Just ask Tom C :-)
The truth is that like all gliders, both are a compromise. The A trades off
cockpit space for performance - real or illusional. The B (and C's in the
current generation of Schempp gliders) potentially trades off performance for
comfort - but it is also more flexible (more pilots can fly it) and hence
generally has better resale value.
Whatever the difference really is, it is probably less than the variation
between gliders that come out of the same molds. I have flown great B's - and
ordinary B's. The good ones would be competitive with most A's - you'd need a
good A to notice a difference.
There are a series of mods to create more space in A cockpits - modified seat
pans (after market) to (I've been told) moving the forward bulkhead forward
about 50mm. I would enjoy comparing a new Ventus2ax or 2cax (to the Discus A)
but then who wouldn't!
BTW, I think that the LS8 cockpit is halfway in between the two Schempp
versions.
Cheers
Bruce

Hi all,
It is hard to imagine that any difference in glide angle between an A or B
model (which is tiny if it is there at all) would cancel out differences in
pilot skill and performance. But it is true that the best pilots will seek
every advantage no matter how small so perhaps that is the reason they chose A
models. It may even be just psyching the opposition. I recall years ago a
Jantar owner painted "Jantar 4" on his glider just before a competition. There
is no such thing, but it sure had the Jantar 2 and 3 pilots wondering.
That said, my Discus A fits me perfectly. And of course it goes heaps
better than a B...
Size does matter... :)
Cheers

Hi all,
I have a question that might have been asked before but I haven't found
it.
How come that there are no minimum cockpit sizes for gliders?
I am following the euros and again the gliders with a small cockpit that
apparently have about half a point better glide are leading. For yesterday the
first 8 are an 'a' model. (or standard small)
To me it looks unfair that your statue gives you a competition advantage.
Thanks,
Mart.
