C-fuselage when it was owned by Martin Heide, and I had bought it
like this. Schleicher has issued a technical note on this (it's an
approved modification), so best would be to talk to them. You'll get
the best of two world's - the advantages of the C fuse, and the 55
deg flaps. The C wins offer no advantage whatsoever.


I had a C model for 11 years, and was under the impression the wings
were slightly different from the "A" wings, mainly to improve resistance
to spinning.

How would the C fuselage provide 55 degree flaps? I think the mechanism
is all in the fuselage, not in the wings.

Well, I don't know how it is done in detail, but my ASW20 had a C-fuselage, the A-wings and 55 deg flaps. I guess that you can adjust the mixer to give 55 deg on the flaps.

The C-wings have no advantage whatsoever, and they are certainly not more spin resistent. I have flown an ASW20C with CG near the aft limit, and it was a bitch.

C is slightly better at high speed from my experience. I owned both and test flew them against each other.
