Bit difficult to tell from last Saturday's flight, but my reseting of the tip wand socket and the sprog seemed to have pretty much cleared things up. It'll take a flight in good conditions to really tell, but certainly I had no major turns. So maybe the tip wand socket was strangely set up rotated by someone who perceived a turn.

The trailing edge is also now pretty symmetric, still maybe a slight rise on the right: the screw is six threads out compared to four on the other side, but I guess this is of no relevance since the engineering tolerance on the tensioning cable cannot be much better than a mm, and that is the aproximate difference. I need to do several long glides, however, to be really sure. I just didn't detect any turns in the last flight.
