Appears there are some ASW-28s for sale.
Having only flown the ASW-24 and '27, what are the differences between the
'24 and '28?

Have owned all 3. Hmm- own all 3 now. Ah well. '28 is the follow on to
the '24 with all the good things the
'24 has plus a few improvements. It has about 6 sq ft more wing area
and an airfoil intended to be less sensitive to gusts(some call
"microturbulence). The outboard end of the wing is much better and the
tip drop the original '24 has is gone. It has fully modern winglets
and "hard tanks " instead of bladders. My view- biased- is that it is
fully as good as the LS-8 or D2.
Simply put- it's a better '24- obviously at a more current price due
to age.
I do a lot of "improving" on my gliders and can find little to mess
with on the '28.
There are a few 28-18's but not many.
Hope this was helpful

28 is slightly longer and a lot more expensive. Never flew a 24 so I
can't compare. I jumped from a 19 to a 28.

Standard 28 panel is smaller than the 24 with deeper cut-outs to allow
more leg room. That limits instrument space. Some were ordered with
the larger 27 panel.

The claim is that the 28 wing works better than the 24 in turbulent
thermals.

The 28 does not seem to be as popular as the D2 and LS-8 but I've
flown against both and don't think I give up anything in climb or
cruise. It does seem to be a bit sensitive to being at the right
speed to climb well.

You should snap up Nigel's before I tell him he set the price too low.

OK, I'm jealous.

Why a 24 AND a 28?

Having flown against both the 15m and 18m versions, my personal
conclusion is that the 18m version has the edge. Great climbing and
great high-speed perfo.
When flown in 15m, it seems a bit less effective.

'24 is actually a '24E "owner modified" project.

I approve that project! Perhaps you could send a report to the "APS
News" (newsletter for the Auxiliary-powered Sailplane Association).

I've flown only the '24 but against quite a few '28s. No discernable
consistent difference in performance so long as the '24 has modern
winglets (see UH about that). '28 has more cockpit room, but my '24
has the factory mods for tall pilots (higher cutouts for the knees,
etc.) so no problem there. I'm cynical about the whole microturbulence
thing: I've always thought it was a marketing ploy to transition '24
owners to the '28, or to explain away the early '24s that didn't
always climb/handle as well. :) Modern winglets take care of that.
I've kept my outer wing with the early '24 sharp leading edge because
I can climb with anything already and always fretted that the "B
mod." (as the blunter outer leading edge is referred to) might cost
some high-speed performance (only in the U.S. Presidential elections
are we promised something for nothing). Others say not but I'm not
inclined to tinker.

Reasons to buy a '24 over a '28: 1. The '24 has perhaps the most
stable wing of any modern composite sailplane. Sand it if it makes you
feel good but the contours just don't budge (mine is 16 years old and
I run the gage on it every year). I'm told the '28 may be more like
the '27 and '29 (i.e., the contours move around a bit the first few
years) although, since I don't own one, this is just hearsay. 2. Lots
cheaper.

Reasons to buy a '28 over a '24: 1. Newer gel coat, trailer, etc., and
2. hard ballast tanks. But I haven't flown with the factory tank
system so I can't compare it with the rapid dump I get using 1" ID
plumbing all the way through or the ease of filling.

Actually I never considered the hard tanks to be an advantage. I flew
my 19 for 15 years with Smiley bags and they were pretty much trouble
free. I had a completely unattended fill system. Just connect it up
and go the pilot's meeting. Come back after and it was full. With
the 28 I have to be there twice to shut off the water at the right
time. Bags are a lot easier to fix than wings if they leak but I have
never heard of 28s having wing leak problems and, unlike some gliders,
the dump valves are easy to remove and service if needed.

Standard 28 is slow to dump even with the later double vents at the
wing tips. Some people have put larger dump valves and modified the
vent system. I have not changed mine.

Yes it's true. The 28 wing had similar issues to the 27 but not
nearly as severe. Schleicher brochures claimed very low empty weight
before the first one flew. The claimed very large range of wing
loading was one of the reasons I ordered mine. Actual weight was I
think about 50lb heavier than the original brochure weight but even
then the wing stability was compromised, presumably in an attempt to
keep the weight down. However the profile distortion seen on some
28s does not seem to have a significant effect on performance. I
don't know how the wing weight compares with the 24 but it's a lot
lighter than the 19 and the LS8.

I'm 6 ft 2 inch with a long torso and easily fit in the 28 without
removing the seat back. I still have a notch or two of pedal
adjustment remaining and more head clearance than in the 19. I seem
to remember that the 24 was too small for me but that was with a
conventional back parachute and the seat back in.

Hard tanks might be an advantage if, like me, you trailer to the
gliderport every day. That tends to abrade the bags so I only install
them in the wings for a contest after I arrive. It's a hassle to use
water for practice flights at my home airport so I never do it.
Filling is very easy and dumping is amazingly fast with big valves and
plumbing.

I'm 6'3" (190+ cm) and cannot fit into a '24 with the seatback
installed (mine arrived without it; the factory substituted the
baggage compartment covers of the '24E to form a backrest) or with
most parachutes. I'm fine in a '27 and assume the '28 is equally
roomy. Early '24s (first 32?) were even tighter in the cockpit.

Well,
I´ve got both. 300 hrs in the 24 and 300 in the 28 and I must say that I
was a little disapointed with the 28.
I think that the 24 climbs almost as well as any other glider. I´ve fown
it at the Britsh Overseas Nationals for two years with the 24 and another
two years with the 28 and I feel that the last one may be a little better
in very weak conditions and better in very strong weather if you fill it
up with almost 200 L of water !
As I live in Spain, we don´t have weak conditions for long periods so the
24 is just fine. Anyway you can also fly the 28 10 kms or more slower than
the 28.
I could say the 24 has been my best glider. If you fit in the cockpit
(smaller than the 24), you find one with the water bags in godd condition
and you won´t fly in very weak weather, it´s not worthy to buy a 28 as it
cost double.
I also find the 24´s roll rate better that the 28.
It always depends on the overall gilder conditions and the money you want
to spend.....

What would be a ball-park figure for ASW 28-18 in good condition? Anybody help.
