Akaflieg Karlsruhe AK-X
Yep, as I said in a post above, the oscillation was damped with an aft, but then the stall characteristics turned to nasty. Most of this nastiness was cause by spanwise flow during stall which caused the whole wing to stall very rapidly. We then installed the boundary layer fences (iirc two per wing), and things improved.
