Hey everyone,
during my last couple of flights I noticed that the stores mentioned above have something odd about their drag models. They even generate so much drag, that the plane flies like in crosswind conditions, sometimes up to 2-3 degrees to either side. Since I am currently not at home, I can't give any Tracks or other evidence about this. But I'll upload those as soon as I come back from my trip.
Maybe someone can test that in the meantime.
Cheers
