The ASK18 I flew from Four Counties gliding club at Syerston, back a few years, certainly enjoyed thermalling to the left rather that the right. It also enjoyed a large boot of right rudder on approach to land. Now, having carried out servicings on the said glider, I could find no asymmetry in the airframe, nothing likely to cause any bias, but flying it always led to a boot full of right rudder. Go figure, as our American friends might say !!
